The Rival Arms Slide Completion Kit for Sig P320 (brand part number RA42P001A) gives you every part needed to assemble the internal workings of your slide in one box, all engineered to work together for real accuracy and consistency. Select parts wear a PVD coating while others are CNC-machined from solid stainless steel billet, so you’re not mixing mystery-metal components from different sources. The kit covers the full internal build: striker spring, extractor, striker safety spring and safety, back cover plate, extractor depressor plunger, RA precision striker, spacer sleeve, depressor plunger spring, and spring-loaded bearing. No gunsmith is required, everything is designed to drop into place.
