They shoot Limited 10.
Seriously though, it does give those an option at a tricked out gun, sans optics and comps. Why do we need single stack? For years so many claimed the 1911 is the ultimate fighting handgun, it’s only limitation being capacity. Why not roll them into Limited 10? Why do they need, as you put it, a “special needscategory” division? I’d even go so far as to remove the .40 caliber major restriction on limited 10.
I shoot a few matches in NY every month due to how close I live to it. I see 1 or 2 L10 shooter at a given match, limited and open are surprisingly popular.
As per USPSA rules if you live in a ban state you are running 10 round mags anyway and the stages seem to be better designed to accommodate that fact.
I stumbled onto what I believe is a P09 OEM magazine with the +2 OEM extension. Assuming this is it, it seems a bit long when I tried it in my 140mm Springer Precision gauge.
Likes pretty much everything in every caliber.
