I had a full size a few years ago. A little big for daily carry. I sold it and found a compact. The compacts are the cats meow. I too like the cocked and locked, as well as the magazine release. You don't have to break your hold to drop the mag. Getting parts from HK on the other hand can be a bit of a hassle. The one thing I have found out about the germans' is they like small funky shaped springs.
I just got a H&K USP 40, does anyone have any experience with one. I have not had a chance to shoot it yet. Likes/dislikes?? I received the gun as a trade, like new in the box.
