Steel Challenge Divisions in 2026: All Sixteen, Correctly

The two things everyone else gets wrong

• “Open” is not a rimfire or carbine division name. The optics sub-divisions in Rimfire Pistol, Rimfire Rifle and Pistol Caliber Carbine are called Optics — RFPO, RFRO, PCCO. If a guide tells you to sign up for “Rimfire Pistol Open,” that guide is out of date and so is the person who wrote it.
• Limited Optics is no longer provisional. The March 1, 2026 change log removes the provisional designation from Appendix D10. In the same edition, Rimfire Revolver was added as Appendix D11, provisional — so the provisional label moved, it did not disappear.

Two shooters, two divisions, same stage, same clock. The division only decides what your time gets compared against.

All eleven equipment divisions

Each of these is an appendix in the rulebook. The five marked with a split are scored as two separate divisions.

Handgun, centerfire

• Open (Appendix D1) — .38 / 9x19mm minimum. Optics, compensators, barrel ports and slide ports all permitted. Maximum magazine length 6.742″. The anything-goes division.
• Limited (D2) — iron sights, no compensator.
• Limited Optics (D10) — an optic is required, and it must mount directly to the slide between the rear of the slide and the ejection port. Frame-mounted optics are not legal here. No compensator, no barrel ports. Magazine length 5.561″, or 6.742″ in single stack guns. No longer provisional as of March 2026.
• Production (D4) — the stock-gun division.
• Single Stack (D5) — 1911-pattern guns.
• Carry Optics (D7) — a slide-mounted dot on an otherwise production-style gun. The most popular centerfire division at most club matches.

Revolver

• Revolver (D6) — splits into ISR (Iron Sight Revolver) and OSR (Optical Sight Revolver). .38 / 9x19mm minimum. ISR gets no optic, no compensator and no barrel ports; OSR gets all three. Self-loading revolvers with retractable slides are specifically excluded.
• Rimfire Revolver (D11, provisional) — splits into RRI and RRO. .22 LR only. No compensators, no barrel ports. Speed loaders are recommended at Level I and mandatory at Levels II through IV. New in the 2026 rulebook.

Rimfire

• Rimfire Pistol (D3) — RFPI and RFPO. .22 LR only. Compensators permitted, suppressors prohibited, lasers prohibited. No forearms, foregrips, stocks or stock-like devices. Gun is cased or holstered until “Make Ready.”
• Rimfire Rifle (D9) — RFRI and RFRO. .22 LR only. Compensators yes, suppressors no. Slings are allowed during the course of fire but not for transport. Chamber flag mandatory in transit.

Carbine

• Pistol Caliber Carbine (D8) — PCCI and PCCO. 9mm, .38 Special, .357 SIG, .40 S&W, 10mm and .45 ACP. Maximum muzzle velocity 1600 fps — a Steel-Challenge-specific limit most PCC content never mentions, and the reason you do not bring your hottest 9mm load to a steel match. Side-by-side magazine couplers are prohibited; end-to-end coupling is allowed.

The sixteen scoring divisions

This is the list that matters when you register, and the list your classification card is built from. Ordered by peak-time benchmark, fastest to slowest — the full benchmark table is on the peak times page.

Codes are the sub-division abbreviations printed in the rulebook appendices. The rulebook does not print a code for Open, Limited, Limited Optics, Production, Single Stack or Carry Optics, so those are left blank rather than guessed at.

What changed on March 1, 2026

The 2026 change log is published only as a PDF and we could not find a single plain-English writeup of it anywhere. Here is what moved, division-wise and otherwise.

• App. D10 — “Provisional” removed from Limited Optics.
• App. D11 — Rimfire Revolver Division added, provisional.
• 6.5.4 — new rule prohibiting binary triggers, forced-reset triggers, triggers that fire on pull and release, and bump-fire stocks. If you have an FRT in your carbine, it is not legal at a Steel Challenge match.
• 2.2.1 — new construction standard for shooting boxes: fixed firmly in place, minimum 0.75″ thick on hard surfaces, 1.5″ or more on softer ground.
• 5.2.2 — an equipment-change violation now may result in disqualification rather than automatically doing so.
• 7.3.2.1 — at Level II and above, penalty, safety and procedural calls are restricted to assigned staff.
• 8.6 — a reshoot may now be offered for external interference, provided the decision is made before the competitor sees the result.
• 10.3.3 — you may intentionally place the firearm on the ground under defined conditions: maintain contact, stay within three feet, follow the safety rules, gun in the specified ready condition.
• 11.3 — a denied protest fee is now retained by the match rather than forwarded to USPSA/NROI.
• App. A3 — Peak Stage Times added to the glossary as a defined term.

The rest of the rule set — what a miss costs, the 30-second ceiling, and the two start positions — is covered on our scoring and penalties and start position pages. New to all of it? Start with the complete guide to the sport.
