Installed on a sig 320 - InForce APL Compact, LED, 200 Lumens w/ MIL-STD-1913 Rails

I purchased this to go on my SIG Sauer 320. I have my 320 configured in both full size and sub compact(railed grip). Works in both configurations. Only difference is it extends beyond the end for the barrel slightly in the sub compact configuration.

Other then that, great access with either the trigger finger or other hand, and illumination is very bright.

Great add-on for home security.
