Re: 1st Polymer pistol
HK USP 45 is the best pistol I own, dont get me wrong, I love the 1911, my TRP operator is second on the list but for polymer the USP 45 is awesome, the newer HK45 is also a badass pistol, I had one for about 4 months but let it go in a trade for the TRP. I have 4 HK pistols and 2 glocks, the only non-polymer pistols have are 1911's. While the HK's are considerably more expensive than say an M&P or a XD or even a glock, they are well worth it in my eyes. The 2 stage recoil system has a really nice feel to it, dare I say better than a Glock? If you are looking to mount a light or something to that effect on the pistol I would urge you to go with an HK 45 as it has the standard rail as opposed to HK's own rail, which greatly inhibits what you can put on the pistol.
Hope this helps,
