I searched the threads for ideas on attaching a rail and found some on the C9, but nothing for the older guns. I want it in front of the trigger guard to mount a laser or maybe a light. The metal is pretty thin on the frame up there so just drilling a hole and cutting threads for bolt through rail likely won't work. Doesn't look like anything can stick up on top of the frame and still allow the slide to move back and forth. Any suggestions or am I out of luck?
