Normally I don't have problems working on my own guns but this one has me baffled. Until now the the mag has never had a problem sliding and seating in the mag well. I just recieved an extra mag from KT and a +1 extension and installed it in the new mag. When I tried to slide it in the gun the top of the mag, or maybe the follower, seems to be getting stuck on the mag release and it won't go any further without pressing the mag release button and sliding it in that way. This was the new mag. After comparing the new to the old I could not see any difference whatsoever between the two. When I tried reinserting the old mag it did the same thing. When the mag is out of the gun the RIGHT side of the mag release is recessed about 1/32 of an inch to the LEFT (toward the inside of the well). So I cannot effectively seat either mag without first pressing the button and I don't like that. It wasn't that way before and the gun worked fine a couple of weeks ago. Any advice/suggestions on the matter would be greatly appreciated since this is my primary carry gun 90% of the time. Can anbody help?
