So if you have any experience with kwa usp or usp compact tell me if it would be a good gbb.
My experience is mostly positive, despite the tons of things I don't like about the gun (I find it's easier to review the things I don't like so that I know what to look for if I need something new).
Quality and reliability are not too bad, as far as airsoft replicas go. The ability to decock the hammer is useful but adds complexity (mechanically speaking). After a year of use, the decock / safety lever has no tension on it, so it just rotates freely (but it still works)
The proprietary rail system is a huge middle finger from H&K because they had to be different. The placement of the mag release is also a huge dick up... because H&K suck and had to be different >:/
I dislike the complexity of the DA/SA trigger and the external hammer. I prefer striker-action trigger systems, but for what it's worth, the USP is a good pistol for airsoft.
