I was really, properly surprised at how soft-shooting it is. I mean, it really is lovely. Also, the crap I occasionally hear people spout about how bad HK triggers - particularly their DA triggers - are has always been wrong in my experience (had a HK USP Compact 9 for a short period of time before this and I've dry-fired a DA/SA P30 in a local gun shop before); I have a P228 tuned up by GrayGuns with a near-as-makes-no-difference "perfect" combat trigger on it (smooth as silk 9.5 lbs DA, super crisp 4.5 lbs SA with an unbelievably short reset and a gnat's ass-hair worth of overtravel) and I think the trigger on this pistol is damned good for a factory trigger. DA is very smooth, light enough (I'd guess ~9 lbs), and SA is light and crisp enough with a reasonably long reset for a combat pistol (notice I said "enough" and "combat", not "perfect" or "match grade").
Still don't like the paddle mag release and plan on getting the...what's the larger/extended one you can have fitted to the USP? Is it the one from the HK 45 Compact? I forget.
It'll also probably take a trip to GrayGuns at some point...I've got a P226 that needs to go in there as well so they'll likely just go at the same time when I get the money together for it.
I'll be carrying this pistol as my "hog defense gun" when I go out in the woods. I'm in Texas and we have a serious hog probably around here, plus they're genuinely dangerous and aggressive, they will attack people (frequently in packs, hence the reason you'll see deer hunters in the woods around here with AR-10s and M1As with 20 rd magazines - the 1st round is for the deer, the other 19 are in case of hog attack). I was planning on loading it up with this stuff, 255gr Hard Cast +P from Buffalo Bore - I'll take any other suggestions if anyone has them. Yes, I too have heard that the USP can handle .45 Super with no modifications, but I'm still not sure if I'm brave enough to try that or if it would be worth the increase in recoil...seems to me like some of that hard cast +P like I linked to above there would be sufficient (for hog).
Oh, and props to Top Gun Supply! They're who I bought it from. I was going to buy from Bud's (I have an account there) but at the last minute figured I'd give them a chance since I've never ordered a gun from them before and they were 10 bucks cheaper. I ordered on Monday and, much to my surprise, it got here on Wednesday! I was expecting Friday but apparently they sent it 2nd day air for some reason. Super fast shipping and only $9.95 (that's their flat rate for all handguns)! Thanks guys, good service and good deal. My total came out to $869 after a $20 transfer fee, then minus the $200 rebate I should have from HK in a couple weeks and that brings me out to $669 for a brand new (manufactured this year, BE date code) HK USP .45 full-size.
