it jammed unbelievable yesterday. it's just over 1000rd, when back to the range and within 150rd, it jammed 24 times!!! that is not acceptable. after fifth ftf i knew it should not be therefore i start paying attention if i'm limp writing, but it still ftf. i changed the ammo i was using from wwb(which for 1000rd, never have a problem) to blazer brass but still ftf about 10 more. the gun have never been taken apart yet, i just when over 1000 rounds. i'm thinking to sent it back alone with my 10rd mag which have been ftf the last round every time since i have it. this is really not acceptable. the first 1000rd it was great, and even yesterday it was perfect(accuracy) except the ammo ftf.
