Does yours have the little bow-shaped tension strip that provides tension against the rail of the pistol? I got mine yesterday, and noticed the gun rattled with each step I took. This morning, I looked at the holster, and it has the slot the strip fits in but no tensioner. I'm a bit pissed, as the gun wobbles a good deal. I just looked at the SERPA I have for my M&P45, and it has the tensioner.
I'm thinking about writing Blackhawk telling them about this.
