I've had at least one USPc 40 since about 1996, but like a fool I sold mine last year to help fund a Tavor X95. I have a P2000SK DA/SA (that's V3, right?) and a VP9. I have about a dozen mags for the USPc, mostly 12 rounders, that of course work with the P2KSK, and half a dozen mags for the VP9, which I understand fit the USPc 9. I am yearning once again for a USPc, V1, but can't decide if I'd rather have a 9 or another 40. I have some muscle loss in my right hand from ulnar nerve impingement, so the 9 is definitely more pleasant to shoot-my S&W PC Shield 9 is significantly softer shooting than my USPc 40 was, so I think the USPc 9 would be a relative pussycat. On the other hand, I have a lot more mags for the 40 for the end of the world scenario. This isn't a 9 vs 40 post, it's more of a logistics and wear and tear on my mitts question...for those with both, how much difference do you feel with respect to recoil and speed of follow up shots? There are a ton of 40s out there for sale at relatively reasonable prices, but a whole lot fewer 9s...
