I recently purchased the hfc m190 ). The gun was brand new. The outer barrels gun metal grey paint had scraped off a bit due to a metal fault in the casting of the slide (propspective customers racking it). There was also a small raised casting fault on the bottom of the slide (where it rests and slides on the frame) but that doesn't appear to affect performance. I'm going to smooth it down a bit anyway.
I've only played around with it doing a little IPSC style stuff in my backyard (DIE EVIL SOCCER BALLS) and I LIKE it. I was going to sell it initially but it's just too nice for anybody else to have. Yeah the trades make you look twice and I'm not sure it's super realistic that a Beretta has a rail, but I like the beretta grips and I like having a rail.
I've no experience with the KJ pistol at all but I know a lot of guys on my team (
www.tac4airsoft.com ) have the KJ m9's ( not the elites ) and they seem to like them ok.
enjoy!
