I just got back from testing a gun that's been offered to me. It's an HK USP Compact in .40 S&W. I put almost 100 rounds through it, but also got to shoot some other variants he brought.
The weapon fits nicely in my hand, and is practically the same size as my Taurus Millennium PT111. I adapted to the trigger pull and, to my surprise, grew quite fond of the magazine release. The only problem I encountered was rapid fire, during which I felt the etching on the grip wasn't strong enough. I had to make an conscious effort to keep a tight hold on it so the recoil wouldn't throw it off balance. I think some hogue would rectify this.
So after that I shot the full-sized .45 USP he brought along and noticed a world of difference. The recoil was gentler and the weapon just seemed to "click" better with me. If I had to choose, I would have bought this one, despite its size. Sadly, it's not for sale.
I'm being offered the .40 Compact along with the box, three mags and a Fobus holster. I tried the holster out and discovered that it works flawlessly, requiring very little effort to draw from concealment. The current price is $680 (might be able to talk him down), but I told him that I won't be able to think about buying until after Christmas. If someone else comes along and gets it, that'll be fine.
I suppose this is more of a review than a post asking for advice.
What do you all think of the USP series?
