Carry Optics, usually shortened to CO, has grown into the most popular division in USPSA. The reason is simple: red dot optics that once cost a fortune are now mainstream on carry and duty pistols, and CO lets you compete with the gun many shooters already own. Here is a complete, plain-English guide to the division.
What Carry Optics is
Carry Optics starts from a Production-style base — a striker or hammer-fired service pistol — and adds one key allowance: a slide-mounted red dot optic. That single change is what makes the division. You get the faster target acquisition of a dot without the full race-gun build of Open.
The equipment rules that define CO
- One slide-mounted optic. A single red dot, mounted to the slide. Iron sights may co-witness but are optional.
- No compensators or ported barrels. Recoil management comes from technique, not hardware.
- Magazines up to 140 mm. Magazine length is capped at 140 mm, so capacity depends on your caliber and magazine choice.
- Minor scoring only. Every competitor in Carry Optics is scored at minor power factor, with a 125 minimum. There is no major in CO, which shapes how you think about accuracy.
- A maximum handgun weight. There is a weight limit for the gun; confirm the current figure in the USPSA rulebook, since equipment rules are updated periodically.
Why minor-only scoring matters
Because everyone in CO shoots minor, a Charlie is worth 3 points and a Delta is worth 1, while an Alpha is worth 5. The gap between an Alpha and a Charlie is larger at minor than at major, so accuracy is rewarded heavily. Chasing speed at the cost of Charlies and Deltas costs you more in Carry Optics than it would in a major-scored division. To see exactly how that math works, read major vs. minor power factor.
Setting up a Carry Optics pistol
You do not need an expensive build. A common, competitive CO setup is a service pistol with an optic-ready slide, a quality red dot, a reliable competition holster, and magazines that reach but do not exceed 140 mm. Many shooters run the exact pistol they already carry. Start with what you own, shoot a few matches, then refine.
Classification in Carry Optics
Carry Optics has its own classification, separate from every other division. You earn a class — D through Grand Master — from your classifier scores in CO specifically, using USPSA best-6-of-8 math. If you also shoot Limited or Production, those classes are tracked independently. Learn how the class system works in how USPSA classification works, and what each class means in .
