I have a Racer holster for 1911 which I haven't used for a couple of years. The holster was a generic 1911 BUT the problem is that not every 1911 trigger guard is the same dimension, it fits fine for my Springfield loaded but didn't fit well for an STI Spartan or a Nighthawk or Springfield Range Officer so it's been relegated to the holster draw. You want to make sure you get one to fit your gun specifically if you can. The issue was how much movement of the gun there was, the gun would probably never have fallen out but wasn't happy with it.
I now use an Apha X for my Sig 320 RX and X% and couldn't be happier with it. Although after using it all weekend last week I have bought the thigh pad to try out.
