||I have had this gun for about a year and a half now. Overall, this is an excellent gun. My version is not actually the fancy "fully licensed" H&K version, it's the "KP45" Tactical; although the two are the same thing, just with different trades. I've been to quite a few skirmishes with this thing, and it almost never lets me down. (There was one case where it jammed in the heat of the battle, and I had to drop it and switch to my rifle.) It's pretty durable, and has a very realistic, solid feel to it. I've even had someone say that it felt like the real steal, so be careful with this thing.
One major problem I had with this gun was that the trigger actually did break about a year and a couple months into owning it. It was a stress fracture that was largely my fault for dry firing it (without gas or BBs) while it was brittle from the cold. I sent a ticket into KWA and was able to purchase a replacement trigger for 6 bucks. Seems easy enough, but I actually had to disassemble the entire firing mechanism to get the new trigger on. Luckily, KWA provides detailed diagrams for all of their guns. Other than that, I've had no real problems with it.
- Hard kick. Feels like a .22, and sounds like one too.
- Realistic feel. I've shot a USP .45 a few times before, and this thing comes close as far as construction goes.
- The FPS is adequate. It hits hardest after you put fresh gas in.
- Quality construction; nothing wobbles too much after a year + of use.
- Even though my trades are lame, they still have serials which is nice. And the new trades are awesome.
- Disassembling it is easy. I can field strip it in less than 20 seconds.
- Has a healthy appetite for gas. I'd recommend getting a propane adapter and some silicon oil. Propane tanks cost ~$2, and hold more gas. The downside is that it smells horrible, so get green gas if you're shooting inside (CQB)
- Slide has jammed up or locked on a few occasions. It doesn't happen often, but when it does, I have to field strip it and put it back together. Hasn't happened since I replaced the trigger, though.
- Accuracy is hit or miss (no pun intended). Sometimes it's dead on, sometimes I'll waste a mag hitting nothing.
- Spare mags are expensive. $40? Yikes. Suffice to say that I haven't needed one yet, so it's no big deal.
- The safety no longer works. This happened after I replaced the trigger, so it must have been a mistake in reassembly on my part.
- The de-cocking mechanism has never worked for me.
Overall: 4.5/5 stars. If you like the H&K USP, this is the best of its class. (Besides the other variants)
