As I was planning to buy a LCP Max this pinching finger got me curious, I did own the first LCP back in 2013 & didn't have this issue, I sold it for other reasons, well this morning I went to a gun store with the intention of buying this LCP Max as I handled the gun I did have this pinching issue after inspecting the problem I think the polymer frame is the culprit, a small file
could be used to take the sharp edge off a little may just fix this problem. I think this could be done without any disassembly of the firearm.
