What Is Compact Carry Pistol (CCP)? All 8 IDPA Divisions Explained (2026)

IDPA Divisions Explained

IDPA Divisions Explained: What They Are and Why They Matter

IDPA divides competitors into eight divisions — SSP, ESP, CDP, CCP, CO, REV, BUG, and PCC — each one built around a different type of handgun commonly carried in the real world. Picking the right division means you compete with the gun you already own, spend less on equipment, and get matched against shooters running similar setups.

I watched a guy show up to his first IDPA match with a bone-stock Glock 19, sign up for SSP, and wonder why his 10-round magazines kept running dry while everyone else was loading 15. He didn’t know CCP existed — a division literally built for the compact pistol he already carried. He still had a great time, but he spent the entire match doing extra reloads he didn’t need to do.

That story repeats itself at local matches everywhere. The eight division codes on the registration form look like alphabet soup to a newcomer, and picking the wrong one doesn’t disqualify you — but picking the right one saves you money and frustration from day one.

The logic behind IDPA’s division structure is simple. SSP represents the full-size service pistol you might keep at home, CCP is the compact gun on your hip every day, and CDP is the classic .45 ACP 1911. This is fundamentally different from USPSA’s approach of dividing by modification level — IDPA cares more about “what type of gun are you carrying” than “how much have you modified it.”

This guide breaks down all eight IDPA divisions with their rules, recommended pistols, and the 2026 rule changes you need to know (BUG capacity jumped to 8+1, and .380 ACP is gone).

SSP: The Classic Starter Division

Stock Service Pistol is one of IDPA’s oldest and most popular divisions. Its premise is simple: a near-stock full-size striker-fired or DA/SA pistol, minimum caliber 9mm, magazine capacity capped at 15 rounds, and maximum weight of 43 ounces.

SSP has strict modification limits. You can swap sights, change grip panels, and do internal trigger work, but external magwells, compensators, or anything that adds weight is off the table. The point of these restrictions is to keep everyone on a roughly level playing field — matches are decided by skill, not equipment.

The Glock 34 dominates SSP with about 16% of all competitors using one. Its 5.3-inch sight radius combined with Glock’s legendary reliability makes it the default answer. The S&W M&P 2.0 is another favorite, with its grip angle and trigger feel winning over many shooters. If you prefer the solid heft of a metal frame, the CZ P-09 and Beretta 92 series are also legal choices in SSP.

One important note: as of July 2025, all SIG P320 variants have been banned from IDPA competition. This decision stemmed from numerous reports of uncommanded discharges, and it affected many shooters who had been using the P320 X-Five Legion. If you own a P320, you’ll need to consider alternative options.

IDPA SSP Division Shooting

Carry Optics has grown rapidly in recent years and has overtaken SSP as IDPA’s most popular division. The reason is intuitive — more and more people are mounting red dots on their carry guns, and the CO division reflects that trend.

CO rules are essentially the same as ESP but with slide-mounted optics allowed and a maximum weight of 45 ounces. This means you can compete with a Glock 19 MOS wearing a Holosun 507C or Trijicon RMR — the same pistol you carry daily.

For shooters already comfortable with red dot sights, CO is the most natural choice. Red dots make aiming faster and more intuitive, with a clear advantage on stages requiring rapid transitions between multiple targets. If you’re still deciding whether to mount a red dot on your pistol, check out our Pistol Red Dot Sight Complete Guide for selection and zeroing details.

What Is Compact Carry Pistol (CCP)? IDPA’s Everyday Carry Division

Compact Carry Pistol (CCP) is the IDPA division designed for compact semi-automatic pistols used in daily concealed carry. If you carry a Glock 19, SIG P365XL, or a similar-sized pistol on your hip every day, CCP is the division built exactly for that gun.

The eligibility rules are precise. A CCP pistol must fit inside a 7¾ × 5⅜ × 1⅜ inch test box, have a barrel length of 4⅜ inches or less, weigh no more than 38 ounces unloaded with the heaviest magazine inserted, and be chambered in 9mm or larger. Magazine capacity is capped at 10+1 rounds. These dimensions describe the Glock 19 almost exactly, which is why the Glock 19 has become the de facto CCP pistol and the most common gun you’ll see at the line.

Other popular CCP choices include the Glock 19X, Glock 45, Glock 48, SIG P365XL, S&W M&P 2.0 Compact, and Springfield Hellcat Pro. The SIG P365 (standard) can also compete in CCP, though its 10-round capacity sits right at the limit.

The appeal of CCP is straightforward — you compete with the gun you actually carry every day. The concealed draw, tactical reloads, and cover movement you practice in competition translate directly to real defensive scenarios. Many shooters who take daily carry seriously choose CCP because it offers the highest real-world training value of any IDPA division.

CCP vs SSP: Which Division Is Right for Your Carry Gun?

If you own a compact pistol like a Glock 19 and you’re deciding between CCP and SSP, the answer comes down to one question: do you want to compete with it as a carry gun or as a range gun?

CCP is the realistic carry division. Its 10+1 round limit mirrors what most people actually chamber in their concealed carry pistol, and the size restrictions ensure you’re running a genuinely compact gun. SSP allows up to 15+1 rounds and a heavier 43-ounce weight limit — the SSP competitor pool is dominated by full-size pistols like the Glock 34 that most people wouldn’t carry concealed day-to-day.

Practically, a Glock 19 can shoot either division. In SSP, it runs the full 15-round magazine. In CCP, it’s capped at 10+1. Most new shooters who carry a compact pistol daily choose CCP because it reflects their real setup and gives the most applicable defensive training. Competitive shooters who want higher round counts and don’t care about carry realism tend to stay in SSP with a Glock 34 or similar.

ESP, CDP, and the Remaining Divisions

Enhanced Service Pistol (ESP) opens up more modification options than SSP. You can add external magwells, do aggressive grip texturing, and it accepts single-action pistols like the 1911 and 2011. Everything legal in SSP is also legal in ESP, so if your modifications exceed SSP limits, ESP is your home. Magazine capacity is 10+1 rounds, minimum caliber 9mm. Many shooters who favor the CZ Shadow 2 or modified Glocks land here.

Custom Defensive Pistol (CDP) belongs to the .45 ACP. This division requires .45 caliber, caps magazine capacity at 8 rounds, and sets a 43-ounce weight limit. The 1911 is the star here — a Government-size 1911 with a magwell, upgraded sights, and trigger work is CDP’s standard setup. If you love the 1911 platform, CDP lets you compete within that classic framework. However, the higher cost of .45 ACP ammo and stronger recoil make CDP’s entry barrier somewhat steeper.

Revolver (REV) gives wheelgun enthusiasts their own arena. Barrel length is limited to 4 inches, capacity is 6 rounds (.38 caliber) or 5 rounds (.44/.45 caliber). The Smith & Wesson 686 and Ruger GP100 are the most common choices. The biggest challenge with revolvers in IDPA is reload speed — using speedloaders to reload six rounds under time pressure takes serious practice.

Back Up Gun (BUG) is designed for pocket pistols and micro handguns. As of the 2026 rulebook, semi-auto BUG capacity has increased to 8+1 rounds (up from 6+1), and .380 ACP has been removed from eligibility — BUG now requires 9mm minimum, just like most other divisions. Revolvers remain at 5 rounds. Engagement distances are shorter, typically within 7 yards. The capacity bump makes micro-compact 9mm pistols like the SIG P365, Springfield Hellcat, and S&W Shield Plus natural fits for BUG, while the .380 removal means your Ruger LCP or S&W Bodyguard .380 is no longer eligible.

Pistol Caliber Carbine (PCC) is the newest division, allowing shooters with 9mm carbines to participate in IDPA. However, PCC hasn’t gained as much traction in IDPA as it has in USPSA.

Which Division Should You Choose? A Beginner’s Guide

Choosing a division doesn’t need to be complicated. The simplest approach is to ask yourself one question: what gun do you already own?

If you have a full-size 9mm — like a Glock 17 or 34, M&P 2.0, or HK VP9 — SSP is your starting point. If that gun has a red dot mounted, sign up for CO. If you carry a compact like a Glock 19, CCP is the natural fit. Own a 1911 in .45 ACP? CDP is waiting for you.

Division Min. Caliber Mag Capacity Max Weight Popular Pistols Entry Difficulty
SSP 9mm 15+1 43 oz Glock 34, M&P 2.0 Low
CO 9mm 10+1 45 oz Glock 19 MOS + RDS Low
CCP 9mm 10+1 38 oz Glock 19, P365XL Low
ESP 9mm 10+1 43 oz CZ Shadow 2, 1911 Medium
CDP .45 ACP 8+1 43 oz 1911, Glock 21 Med-High
REV .38/.44/.45 5-6 rds — S&W 686, GP100 High
BUG 9mm 8+1 — SIG P365, Hellcat Medium
PCC 9mm Per rules — 9mm Carbine Medium

For beginners, SSP, CO, or CCP are the most recommended starting divisions. These three have the most accessible starter equipment, the lowest ammo costs (all run 9mm), and the largest competitor pools — meaning you’ll find more people at your level to learn from and compete against.

Don’t buy a new gun just for competition. The spirit of IDPA is to train and compete with what you already carry. After a few matches, once you’re sure you enjoy the sport, then consider whether to optimize your equipment for a specific division.

IDPA Classification System Overview

IDPA’s classification system matches you against shooters of similar skill, so you don’t have to worry about getting crushed by Master-class shooters in your first match. Classifications range from bottom to top: Novice (NV), Marksman (MM), Sharpshooter (SS), Expert (EX), Master (MA), and the highest tier, Distinguished Master (DM).

When you first join IDPA, you’re Unclassified (UN) in all divisions. After completing your first classifier stage or performing well enough in a sanctioned match, the system assigns you a classification based on your results. Classifications are independent per division — you might be a Sharpshooter in SSP but a Marksman in CO.

The DM classification is unique in that it can’t be achieved through classifier stages alone. You must win the division championship at a Tier 5 event (Nationals or World Championship) or finish within 3% of the champion’s score to earn it.

💡 Training Tip: Use a Shot Timer to record your times on standard drills, then compare them against IDPA classifier benchmarks to understand where you stand and what to work on. For more classic drill setups, check out the Shooting Drills Complete Guide.

IDPA Competition Stage

Frequently Asked Questions About IDPA Divisions

Carry Optics (CO) has surpassed Stock Service Pistol (SSP) as the most popular division in recent years. The shift happened because more everyday carriers are mounting red dots on their pistols, and CO lets them compete with that same setup. SSP remains a close second, especially among shooters who prefer iron sights.

Can I switch divisions between matches?

Yes, absolutely. You can shoot a different division at every match if you want — just make sure your equipment meets the rules for whichever division you register for. Many experienced shooters compete in multiple divisions to keep things interesting. Your classification is tracked independently per division, so switching won’t affect your ranking in another division.

What gun do I need for my first IDPA match?

Any reliable 9mm semi-automatic pistol will work for SSP, CO, or CCP — the three most beginner-friendly divisions. A Glock 17 or 19, S&W M&P, or similar striker-fired pistol from a major manufacturer is all you need. You’ll also need a sturdy belt-mounted holster (no SERPA or shoulder holsters), at least three magazines, and a cover garment like an untucked shirt or light jacket.

What’s the difference between IDPA and USPSA divisions?

IDPA divisions are organized by gun type and carry purpose — SSP for full-size service pistols, CCP for compact carry guns, CDP for .45 ACP. USPSA divisions are based more on modification level and equipment — Production, Limited, Open, etc. IDPA also requires concealment gear and has stricter modification limits, making it closer to real-world defensive shooting. For a full breakdown, read our IDPA vs USPSA Complete Comparison Guide.

Is the SIG P320 still banned from IDPA?

Yes. As of July 2025, all SIG P320 variants are prohibited from IDPA competition due to documented uncommanded discharge incidents. This ban applies to all divisions and all P320 models, including the popular X-Five Legion. Shooters who previously used a P320 will need to select an alternative firearm.

How long does it take to get classified in IDPA?

You can get classified after a single match. Once you shoot a classifier stage — a standardized course of fire designed to measure your skill level — IDPA assigns you a classification from Novice to Master. Most new shooters start as Novice or Marksman. Your classification updates as you shoot more classifiers, and it’s tracked separately for each division.

What changed in the 2026 IDPA rulebook?

The biggest change is to the BUG division: capacity increased from 6+1 to 8+1, and .380 ACP was removed entirely. This means micro-compact 9mm pistols like the SIG P365 and Springfield Hellcat are now the standard BUG guns. Other changes include: firearms with non-functional manual safeties now result in disqualification, the steel calibration power factor was corrected to 95, and the Match Performance Promotion threshold now requires beating 10 competitors. All changes took effect January 15, 2026.

Can I shoot IDPA with a .380 pistol?

Not anymore. As of the 2026 rulebook, .380 ACP has been removed from BUG division eligibility. All IDPA divisions now require 9mm minimum (except CDP which requires .45 ACP and REV which allows .38 Special). If your only pistol is a .380, you’ll need to upgrade to a 9mm to compete.

What’s the cheapest way to get into IDPA?

A used Glock 17 or M&P 2.0 ($350-450), a Blade-Tech or Comp-Tac OWB holster ($40-60), three factory magazines ($25 each), and a concealment garment you already own. Total investment is around $500-600. Sign up for SSP, buy a box of 9mm practice ammo, and you’re ready for your first match. Most clubs charge $20-30 per match fee.

2026 Rule Changes That Affect Your Division

The 2026 IDPA rulebook (Version 2, effective January 15, 2026) introduced several changes that every competitor should know about. Whether you’re a seasoned shooter or just getting started, these updates might affect which division you choose and what equipment you bring.

2026 IDPA Rule Changes

The most impactful change hit the BUG division. Semi-auto capacity jumped from 6+1 to 8+1 rounds, bringing it closer to the real-world capacity of modern micro-compact pistols. At the same time, .380 ACP was dropped from eligibility entirely. This two-part change essentially redefined BUG from a “pocket pistol” division to a “micro-compact 9mm” division. If you were running a Ruger LCP in .380, you’ll need to switch to something like a SIG P365 or Springfield Hellcat to stay legal.

On the safety side, the 2026 rulebook made it explicit that firearms with non-functional manual safeties now result in disqualification. This primarily affects shooters running 1911-pattern pistols in ESP or CDP — make sure your thumb safety is mechanically sound before you show up to a match. The steel calibration power factor was also corrected to 95, which shouldn’t affect most 9mm shooters but is worth noting if you’re loading light.

Match administration saw a few tweaks as well. The Match Performance Promotion (bump) threshold was revised to require beating 10 competitors, and awards at Tier Two matches now run through 5th place. All divisions must be recognized at Tier Two competitions, which means smaller clubs can no longer skip divisions they don’t typically see.

For most shooters in SSP, CO, and CCP, the 2026 changes are minor. But if you’re a BUG shooter, a 1911 competitor, or a match director, it’s worth downloading the full 2026 rulebook from IDPA.com and reading through the updates.

Conclusion

IDPA’s eight divisions may look complicated at first glance, but the core logic is simple — find the division that matches your gun, then get out there and shoot. Don’t spend too much time researching which division is “the best” because each one has its own appeal and challenges. SSP tests your raw technique with standard equipment, CCP trains real daily carry skills, CDP lets you experience the classic 1911, and CO is the modern arena for red dot shooting.

Your first IDPA match doesn’t need a perfect equipment setup. Bring the gun you have, a compliant concealment holster, three magazines, throw on a jacket to cover your gear, and go enjoy the experience. The IDPA community is welcoming to new shooters, and you’ll learn things at a match that you can never learn practicing alone at home.

Once you’ve picked your division, start tracking your draw and reload times with a Shot Timer so you can measure your progress between matches. And if you’re still deciding which gun to bring, our IDPA Beginner Pistol Guide has specific recommendations for every division and budget.
