I like shooting this gun, but its to big to carry.
I had one for a while... it never worked. It would fail-to-feed at least once every magazine. The main recoil spring appeared to be damaged so I contacted their customer service. 3 times they sent me the wrong spring. I finally gave up and gave it back to my brother (who had loaned it to me). I suppose it could have been sent back to them, but honestly at that point it just wasn't worth the $50 to ship it to them.
I have heard a lot of people who have had great experiences with them, but everyone I have personally known have had bad experiences with them (2 for 2, mine and a friend's). I think it just depends on the one you get. My big complaint was that the customer service couldn't send me the right part in 3 tries.
I have had multiple days of "plinking" where I have run 250 rounds through mine without problems. One time I didnt even clean it and shot another 250 rounds through it a month later. I have shot Magtech FMJ and hollowpoints, WWB, Federal FMJ, and Golden Sabres without ANY problems.
I think you are in the majority too... I think you either get a great one or a dud. My concern was how the dud was handled. It didn't instill a lot of confidence.
