p220 slide lock back issues
Hello - this is my first post...I usually just use the search function and find most of my answers, but this problem has become extremely vexing. I bought a an elite carry stainless p220 in August. I love the gun. It is a joy to shoot, but the slide fails to lock back about half the time after the last round. I have researched this issue to death. I have called sig and even sent it back to them once. Yes the slide locks back when I manually rack the slide with an empty mag. no I am not limp wristing or touching the slide lock lever accidently. Yes I have cleaned the gun multiple times and used every type of lube imaginable in various quantities. Nothing seems to help. Currently I am using Speer Lawman, which Sig suggested, but in 200 gr...Yes I could try 230 grain ammo, but it seems to me that a Sig shouldn't require such fine tuned attention just so a basic function of the gun will work. When I sent it back to Sig they replaced the magazines and the slide release lever and adjusted the SRT trigger. Still the slide locks back only about 50% of the time or less. I have discussed this with Sig customer service and they are also at a loss. What makes it more frustrating is that they continue to insinuate that it is somehow my fault...like they are doing me a favor to try to fix the problem. Despite that, I am sending the gun back to Sig again. I guess my question is: if I get back from Sig and it still fails to function correctly, what are my options besides living with it or selling the gun?
