I just got my M&P 40c today. I took it home to clean it before I take it shooting. While cycling the gun a few times, I went to release the slide lock with my thumb and I can't push it down. Extremely tight! I have to pull both sides of the slide lock down with my other hand.
Does anyone else have this issue? I was trying to think back to my other guns so I went to try them out and have no problems pushing down on the slide lock with my thumb to chamber a round. Don't tell me I got a terd!
