I have quite a few revolvers and pistols, shoot a Sig P230 X5 Legion in competition, but never owned or shot a H&K. Then, a few weeks ago, this 2020 date-coded H&K USP 45 showed, up, pretty in the box, presumably never been shot and quite affordable (I live in California), so I bought it.
I have not shot it yet, but played with it a bit with snap caps. When the slide is all the way back, the slide release engaged, I cannot get it to release by just *trying* to pull the lever down with my thumb. I have to do both at the same time, pull the slide all the way back and engage the slide release lever, in order for the slide to be released. The lever alone won't move without me pulling the slide back. I find that strange and wonder if that's an H&K thing or something that has to do with the fact that the gun is new and super tight.
Thank you.
