"Excellent piece that even somehow manages to have a realistic hammer mechanism that wont shoot with the hammer back unless you "chamber a round" by racking the slide. Great addition to my collection, though, one time a spring came out of the slide where the hammer hits but it seems to have been a weird cosmetic because the gun still functions normally.

"I got this gun a few weeks ago and I love it. It's a very authentic replica of the real gun and it also performs well. I have about 1,000 BBs through it by now and i haven't had a malfunction yet. (Although sometimes it doesn't hold the slide open on the last round) No problems with the magazine yet either. It took a 6 foot drop onto concrete pretty well. I put a Lighter R tracer unit on it and it looks awesome at night. I had to buy a 14mm to 16mm adapter though.

If you're looking for holster options, they are pretty limited but i recommend getting the DTD holster for MK23s. But If you want the real deal safariland sells a holster for MK23s as well. Not sure If that one works with a supressor though.
