Cajun Gun Works Retaining Screw 3500 (Magazine Catch Spring Screw). This screw retains the trigger bar support spring and mag spring, fits all 75 full size and compacts, Shadow 1 & 2, SP-01’s, 85B/C, P-01, 75B/BD, 75D/PCR, 40B, 97B/BD, etc. This is not a factory part, but takes the place of the OEM screw perfectly.

TECH TIP:  When installing this screw, thoroughly de-grease the frame threads as well as the threads on the screw.  Apply a small amount of blue loctite to the screw threads, use the blue only.  Do not over-tighten; over-tightening can ruin the #34 trigger bar support spring.
