There are 2 kinds of 10mm IMO, really, there is the 10mm "for the masses" which is generally in the range of power of a warmer 40 S&W--and then there are the hotter "original Bren 10 spec" 10 mm's which are more powerful; and not surprisingly hit harder in recoil (which is what brought about the 40 S&W in the first place). Strictly just my opinion--but that is the most important criteria IMO when choosing your 10mm pistol. For the really hot 10mm loads--which again extract a price in felt recoil--choose a pistol that can handle the firing and cycling of that kind of cartridge. I'd look for one that has the best ramp support to chamber and full case head support--the case head is what's going to blow when getting up there in max charges if not well-supported.
