But I use it in my .45 cal. G21! It is amazing that the extractor works perfectly from .45 to 9mm. It was NOT designed to do this and I have to change the recoil spring form 18# to 11# but using 10mm magazines it runs 9mm for cheap practice.

That's all I wanted it to do. A truly amazing firearm platform. I bought the G21 and shoot .460 Rowland, .45 ACP, 10mm, .40 S&W and 9mm through it. Not recommending it, just facts for bemusement.
