USPSA Carry Optics Rules: The Complete 2026 Guide
05/14/2026
The Carry Optics division is by far the most represented division at nearly any USPSA match in the county. By the most recent USPSA figures, CO accounts for roughly 37% of all division activity, more than Limited Optics, Open, PCC, and Production combined.
It is not an accident. Carry Optics solved a problem the sport had been quietly choking on for years. Before 2015, if you wanted to compete with a slide-mounted red dot, your only legal option was Open. That meant lining up your stock Glock against frame-mounted optics, brake-and-comp race guns, and Major Power Factor scoring. The mismatch was absurd, and the sport bled shooters because of it.
USPSA introduced Carry Optics in mid-2015 as a provisional category and made it permanent in 2018. The rulebook has been refined every year since. Here is what Appendix D7 actually says in 2026, including the recent changes that affect how you build, hold, and run a CO pistol.
What is USPSA Carry Optics?
Carry Optics is a USPSA pistol division that requires a slide-mounted red dot sight on a factory-style duty pistol. Same base guns as Production, same Minor Power Factor scoring, with a red dot bolted on top and a few additional allowances around magazine capacity and accessories.
Appendix D7 of the current USPSA Competition Rules governs the division. Every firearm used in CO must appear on the official USPSA Approved Production Handgun List, published on USPSA.org and updated regularly.
USPSA Carry Optics Approved Gun List and Firearm Rules
To run a pistol in Carry Optics, the gun must:
- Appear on the USPSA Approved Production Handgun List
- Be striker-fired, DA/SA, or DAO. Single-Action Only (SAO) pistols are not allowed, which effectively excludes 1911 and 2011 platforms.
- Be chambered in 9x19mm or larger (minimum bullet diameter of .355 inches)
- Meet the 59-ounce maximum weight limit with the heaviest empty magazine inserted and optic mounted
- Use ammunition that meets 125 Minor Power Factor at the chronograph stage
No upper limit exists on barrel length or overall pistol size, provided the base firearm is on the approved list and the total assembled weight stays under 59 ounces.
Popular legal platforms include the Glock 34 MOS, Glock 17 MOS, Glock 45, Smith & Wesson M&P 2.0, CZ Shadow 2 Optics Ready, Canik SFx Rival-S, Walther PDP Match, and Sig Sauer P320 X5 Legion. The Glock 35 is technically legal but tactically obsolete in this division (more on that in the scoring section).
If a specific variant of a pistol is not on the Production list, it is not legal for CO. No matter how similar it looks to an approved model. Always check the list before showing up to a match.
USPSA Carry Optics Optic Rules
The optic rules in Appendix D7 are specific:
- The optic must be slide-mounted, positioned between the rear of the slide and the ejection port. Frame-mounted optics are an immediate bump to Open division.
- Sights must be 1x magnification only. LPVOs, magnifiers behind a red dot, and prism scopes are prohibited.
- Both red and green emitters are legal.
- No restrictions on window size, reticle type, dot MOA, or optic weight (so long as total firearm weight remains under 59 oz).
Mounting methods are flexible. Direct slide milling, factory optics-ready adapter plates, and dovetail mounts that replace the rear sight are all legal. The most common setup is a factory MOS-style cut with an adapter plate or a directly milled slide.
For competitive use, window real estate matters more than almost any other optic spec. A slide-mounted optic reciprocates violently with the slide, and the bigger the window, the easier it is to track the dot through recoil and find it on the draw. The Swampfox Justice II runs a 30mm window in the standard RMR footprint, which is what most of the approved-gun universe is cut for. That extra window real estate lets you keep eyes on the dot through the full recoil arc, which is what you want when you are chasing tenths.
A note on the 2026 rule update: If your optic falls off or fails during a stage, it is now treated as an equipment malfunction. You either finish the stage with whatever sighting reference you can manage or stop and take the score earned to that point. You are not bumped to Open. This is a change from previous years.
USPSA Carry Optics Magazine Length and Capacity Rules
Carry Optics has no round-count limit. Capacity is governed by physical dimension instead: every magazine, including the base pad, must fit inside the official USPSA 141.25mm magazine gauge. Extended base pads, aftermarket followers, and tuned springs are all legal as long as the loaded magazine drops freely into the gauge.
In practice, competitors routinely extract 22 to 24 rounds of 9mm from standard 15- or 17-round magazine tubes by adding aluminum or brass extended base pads. On a standard 32-round long course, a well-built CO magazine setup lets you shoot the entire stage with a single reload on the move.
This is the biggest mechanical advantage CO has over Production. Production caps you at 15 rounds per magazine regardless of what the gun will hold. CO lets you load to the physical limit.
USPSA Carry Optics Holster Rules
Holster rules in CO are written to keep the division anchored to real defensive setups, not race-gun engineering. The rules:
- No skeletonized race holsters. The trigger guard must be fully covered.
- No drop-leg or tie-down rigs. These are prohibited in all USPSA pistol divisions.
- Retention hoods or thumb-breaks are legal, but if your holster has one, it must be fully engaged before the Standby command. You cannot bypass a retention mechanism for a faster draw.
- The heel of the butt of the handgun must be no more than 2-1/8 inches from the inner surface of the belt and must sit above the top edge of the belt.
The biggest holster-rule change in recent years was the elimination of the “behind the hip” requirement. Appendix carry is fully legal in CO under the current rulebook. You can run your actual concealed carry rig in competition if you want to, which is exactly what a lot of shooters do.
Weapon-mounted lights are also legal in CO, as long as the light is fully functional. No hollowed-out dummy blocks filled with tungsten weights. The light does not need to be turned on during the stage. This is a real concession to defensive shooters who want to compete with their daily setup.
One more 2026 update worth knowing: under the modernized Rule 6.2.5.1, a gear-position violation no longer automatically bumps you to Open. You get the chance to fix the issue, or if you cannot, you shoot the match for no score. The auto-Open bump that ruined many a first major is gone.
Trigger and Internal Modification Rules
The inside of a CO pistol is functionally an unrestricted sandbox. You can:
- Replace the trigger, sear, disconnector, striker spring, and recoil guide rod with aftermarket parts
- Tune the trigger to virtually any weight (USPSA has no minimum trigger pull weight for CO, unlike IPSC, which mandates 5 lbs for DA/SA)
- Install heavy tungsten guide rods, brass backstraps, and other internal weight to dampen recoil
What you cannot do is disable factory safety mechanisms. Drop safeties, firing pin blocks, grip safeties, and manual thumb safeties must remain functional. A pistol that fails the standard drop-safe test is an immediate disqualification.
External Modifications: What Is Legal vs. What Will Get You Bumped
Legal external mods:
- Aggressive slide milling (forward cocking serrations, lightening cuts that do not constitute porting)
- Stippling, grip tape, or silicon carbide texture on the frame
- Threaded barrels (NROI confirmed under Appendix D7, Rule 21.3)
- Extended magazine releases, slide stops, and altered safety levers
- Weapon-mounted lights
Prohibited external mods:
- Compensators of any kind. Thread-on, integral, porting, muzzle brakes. Any device that vents gas to counter muzzle flip puts you in Open.
- Flared magazine wells. This is the trap that catches more new competitors than anything else. Several popular factory pistols (Canik SFx Rival-S, Walther PDP Match, Smith & Wesson M&P Competitor, Sig P320 X5 Legion) ship with magwells from the factory. You have to physically remove the magwell with an Allen wrench before the match, or you are not in CO.
- Thumb rests (gas pedals). Any frame-mounted ledge for the support thumb is illegal.
USPSA Carry Optics vs. Other Divisions
| Carry Optics | Limited Optics | Production | Open | |
|---|---|---|---|---|
| Optic | Slide-mounted required | Slide-mounted required | Iron sights only | Slide or frame mounted |
| Action types | Striker, DA/SA, DAO | Striker, DA/SA, DAO, SAO | Striker, DA/SA, DAO | Unrestricted |
| Power factor | Minor only (125) | Minor only (125) | Minor only (125) | Major (165) or Minor |
| Magazine length | 141.25mm | 141.25mm | 15 rounds max | 171.25mm |
| Magwells | No | Yes | No | Yes |
| Compensators | No | No | No | Yes |
| Weight limit | 59 oz | None | 59 oz | None |
| Holster | Duty/concealment | Race holsters allowed | Duty/concealment | Race holsters allowed |
Carry Optics vs. Production: Same base guns. CO adds the optic and the 141.25mm mag length. Production caps you at 15 rounds and bans the dot. Most modern shooters coming into the sport pick CO over Production.
Carry Optics vs. Limited Optics: This is the most common upgrade path. Limited Optics was introduced in 2023 and made permanent in the 2025 rulebook, specifically to absorb the 2011 and SAO crowd. If you want to run a Staccato or an Atlas 2011 with a red dot, LO is your division. It also permits magwells and frame-mounted thumb rests. CO stays the home for striker-fired and DA/SA factory guns.
Carry Optics vs. Open: Open is a different sport. Frame-mounted optics, compensators, 171.25mm mags holding 29+ rounds, Major Power Factor. A CO gun is non-competitive in Open.
How Scoring Actually Works in Carry Optics
USPSA scores stages on Hit Factor, which is points earned divided by time elapsed. The shooter with the highest Hit Factor on a stage wins 100% of available stage points. Everyone else receives a percentage relative to their own Hit Factor.
Where CO gets interesting is Minor Power Factor scoring:
| Zone | Major Power Factor | Minor Power Factor (CO) |
|---|---|---|
| Alpha (A) zone | 5 points | 5 points |
| Charlie (C) zone | 4 points | 3 points |
| Delta (D) zone | 2 points | 1 point |
A C-zone hit that costs a Major shooter 1 point costs a CO shooter 2 points. On a 32-round stage, ten C-zone hits = 20 points dropped instead of 10. That kind of point bleed wrecks your Hit Factor numerator no matter how fast you move.
In CO, you cannot afford sloppy hits. The dot makes precise alpha-zone shooting easier than irons ever did. It also tempts you to accept C-zone hits in exchange for raw speed. Do not let it. The math is not on your side.
Common Rule Traps That Catch New Competitors
A few specific things bite first-time CO competitors more than anything else.
The factory magwell trap. Several popular pistols ship with magwells installed. Pull yours off before the match.
The DA/SA start condition. If you are running a Shadow 2, Beretta 92, or any other DA/SA, the gun must be decocked (hammer fully down) at the start. You cannot start cocked-and-locked with the safety on. The first trigger pull of every stage is the long double-action pull.
The chronograph trap. All Level II and higher matches chrono your ammo. Loading right at 125 PF is asking for trouble. Temperature, altitude, and barrel length variance can drop you below the floor. Most Grand Master coaches recommend loading to a 130–135 PF buffer.
Belt distance. The 2-1/8 inch heel-to-belt rule gets enforced. Thick competition belts and aggressive drop-offset hangers regularly violate it. Measure your rig at home before you measure it on a podium with an RO standing next to you.
What to Run for Your First Carry Optics Build
The financial barrier to CO entry is low compared to other divisions. A bone-stock Glock 34 MOS, Glock 17 MOS, Glock 45, or M&P 2.0 with a quality red dot and a couple of extended base pads will get you to Master class if you put the dry-fire reps in.
At the elite level, the meta favors heavy steel- or hybrid-framed guns (CZ Shadow 2 OR, Canik SFx Rival-S, Walther PDP Match, Sig P320 X5 Legion). The added weight dampens recoil and lets the dot return to the window faster between shots.
For the optic, prioritize window size and durability. A slide-mounted dot on a CO pistol absorbs accelerations near 5,000g every time the slide cycles. Cheap optics do not survive this. The Swampfox Justice II offers a 30mm window in the standard RMR footprint, which is the footprint cut into most approved CO guns.
The gear ceiling in Carry Optics is low. The skill ceiling is not. Plenty of GMs got to GM with a stock Glock and an aftermarket trigger shoe.
