Put one on my Springer loaded. Very easy to install, used factory slide stop that came with gun. Problem is, I had a Safariland 6285 holster for the M6X light. Gun with rail and light will not fit,super tight. Tried the Streamlight TLR without laser and still super tight. I did find M3 is 1.5" tall, TLR is 1.4 " tall. TRG recommends Surefire, which is 1.3" tall. Will advised when I try the Surefire light to see if it fits. The light rail system is awesome, just wish I could make it fit in a holster. Any one have any experience with this to see what fits in what holster.

Thanks to all
