Rival Arms Extended Slide Lock - Fits Glock 42 - Black QPQ Stainless Steel

The Rival Arms Extended Slide Lock is a drop-in takedown lock upgrade for the Glock 42, machined from stainless steel and finished in a deep Black QPQ (quench-polish-quench) coating. It is designed to replace the factory slide lock and make field stripping faster and easier.

The extended profile adds surface area for positive purchase during takedown. The stainless steel construction resists the chipping, wear, and breakage that can occur under repeated use, giving you a stronger and more durable alternative to the factory piece.

This is a direct drop-in replacement for the factory Glock 42 slide lock - no fitting required. Rival Arms machines the part to tight tolerances and finishes it in QPQ, a surface-hardening treatment that protects against corrosion and gives the lock its black color.
