thegeneric Posted June 22, 2022 Share Posted June 22, 2022 (edited) Given that the nitro fin for the CZ Shadow 2 and the various slide release thumb ledges for the p320 are both CO legal, is it safe to assume that these following products would be legal on a Glock for CO (since they "replace" the trigger pin)? https://www.tecperformance.com/home/gun-parts/glock-thumb-grip/ Or this: https://stores.sjcguns.com/sjc-glock-thumb-rest-dowel-type/ Thanks in advance for any guidance.

open17 Posted June 22, 2022 Share Posted June 22, 2022 Maybe. The Cz, P320 etc thumb rests are a replacement slide stop or takedown lever. The Glock one you are asking about appears to be on the trigger pin---and pins are on the list. Interesting that "takedown lever" is not---- 21.6 Exchange of minor EXTERNAL components Sights, firing pins, firing pin retainers, pins, extractors, magazine releases, slide stops, thumb safeties, triggers, hammers, bushings, and ejectors MAY be replaced with OFM or aftermarket parts.

GigG Posted June 22, 2022 Share Posted June 22, 2022 That is hardly a "minor EXTERNAL component". The rules allow for a change of barrel. That doesn't mean you can change the barrel with one that has a compensator as part of it. 22 Specifically prohibited modifications and features Please note that the absence of an item in the list of prohibited modifications MAY NOT be construed to mean a modification is allowed. A modification is only allowed in Carry Optics Division if there is a rules clause or interpretation, which specifically declares that it is allowed in the Division.

phoenixsomd Posted June 23, 2022 Share Posted June 23, 2022 This wouldn't be acceptable/legal. Was discussed during last year's PCC/CO Nationals with Troy. The pistols you mentioned have the thumb ledge incorporated into a non-OEM replacement slide stop. Link to comment Share on other sites More sharing options...
sx2gl35 Posted January 12, 2023 Share Posted January 12, 2023 When and if the "USPSA Limited Optics Provisional Divisional Rules" is approved, it looks like both of these might become legal in that division: "Thumb rest permitted - Yes" I got one of the Tec Performance ones to play with in the mean time, and it is an extremely well made product that actually works. Easy to install and rock solid. Had to file off a small amount at the top of my RHT competition holsters to get it to fit; otherwise no alterations needed. I'm shooting Glock 34's and 35's; don't know if they make those for other guns. Obviously, I'm enjoying all the shooting benefits that a thumb rest has to offer. Thank you USPSA if the division is approved! Link to comment Share on other sites More sharing options...
JoeMKY Posted January 12, 2023 Share Posted January 12, 2023 Isn’t one of the catches for co is it has to fit in the holster without any modifications to the holster? I asked on f the nro’s about the sig thumb rests and cz thumb rest that I saw people using and they said as long as it hosts in a production legal holster without modifications to the holster to fit, it was good to go. This looks like it would not fit a regular holster. But I like it I might get it for my Glock open gun. Link to comment Share on other sites More sharing options...

The first one is definitely not legal for CO or P. It's a separate thumb rest that uses a longer trigger pin. The fact that the pin is separate from the ledge is why it fails to meet the allowances of Appendix D4 21.6 and App D7 21.6. Thumb rests (by themselves) are not among the list of approved external modifications. However, 21.6 allows the replacement of externally visible pins with aftermarket ones. If that aftermarket pin has an integral feature where the thumb could rest, then it's still legal because it's all one and the same part (a pin), not two separate parts. CO pistols don't have to fit in the production box, so the extra width isn't a problem. For production, a pin with integral thumb rest would be legal if the pistol still fits in the box. The second one is just an extra long pin. Totally OK by 21.6 in both P and CO. However, the production box will almost certainly make it a no go for production.

Whoever told you that are wrong There is no rule that prohibits holster modifications in Production and CO. As long as the trigger guard is covered, and the slide is covered up to 1/2" down from the front of the ejection port, you can hack away at the holster to accommodate other pistol modification.
