However, you can order a weapon from Sig Sauer with only this special take down lever and then you won't have anything else. Then in this case it is an OEM part or not? I guess it would be different, if Sig wouldn't offer the take down lever on their webpage and i just could buy it as a aftermarket item at the original supplier.

As i wrote above, the front page of the USPSA Rule book stated on the bottom "USPSA/IPSC", so that seems to be confusing to me

Hello everyone, I never thought I would bring this post back to life after almost 5 years. I have been an IPSC shooter for a year and have already taken part in several matches. Unfortunately, about 3 weeks ago in Germany there was a discussion at an IPSC Level 3 match as to whether the take down lever used on the P320 (*thumb rest [generic]*) could be used in the Production Optics Division. The shooter had to reset his X-Five Legion to standard take down lever. In all other previous matches it was never an issue. A range officer had read the following on the Internet at Sig Sauer in the item description of the P320 *thumb rest [generic]*... “Improve your recoil control with this *thumb rest [generic]*® CG. This replacement for the factory P320 takedown lever helps you counteract muzzle rise during recoil with your support thumb.” With this description, the Range Officer perceived it as a thumb rest that is not allowed to be used in the Production Division even though it is not screwed on. Two weeks ago I spontaneously wrote an email to those responsible at ipsc.org, asking for clarification. However, I received feedback via email yesterday that the P 320 take down lever (*thumb rest [generic]*) is not allowed to be shot in the Production Division. There are already other weapons such as the Ruger American Pistol Competition, H&K SFP9, Springfield Echolon, etc. that have a similar characteristic to the take down lever (*thumb rest [generic]*) of the Sig P320 and are still shot in the IPSC Production or Production Optics Division. Unfortunately, it is not clear in the IPSC regulations which internal and external parts can be exchanged. I only found this information in the USPSA Competition Rules (February 2024) Page 101 APPENDIX D4 at 21.5 and 21.6. The cover sheet says also USPSA/IPSC, to what extent do these rules also apply to IPSC shooting? I can't find a reference anywhere in the IPSC rulebook to the USPSA rulebook. Mr. Troy McManus confirmed in 2019 that the take down lever is one of the replaceable parts and therefore you can shoot the *thumb rest [generic]* of the P 320 in the Production Division. Has there been a change in the regulations in the USA in recent years or how is it currently handled in the USA when shooters want to compete in a match with the P320 *thumb rest [generic]*? It would be helpful to get more support from you or to find out more so that we can clarify the issue here. Thank you for your support and opinions
