Cool add for my ruger 57 - FAB Defense Universal Picatinny Rail Handgun Mount

I wanted something to put my optic in front of the chamber so shooting with a suppressor wouldn’t flash blowback on the red dot. This was the solution. Was a little worried about how tight it would get on a polymer frame, but it is holding strong after 50 rounds of FN 40 grains and holding a 1” group off the bench at 30 yards. It didn’t fit on my S&W Shield EZ in 30 super carry as I thought that would be a cool gun for optics to stretch the legs out, but unfortunately it wouldn’t even begin to slide over the PIC rail. I’ll likely order another one for my 1911 since it held tight. I did add some thread locker on the set screw and applied a fair amount of torque to it.
