Rival Arms RARA80G004A Extended Slide Lock Black QPQ for Glock 42

The Rival Arms Extended Slide Lock for Glock 42 is a purpose-built upgrade for shooters who want better control and manipulation of their compact carry pistol. If you've found the factory slide stop lever too small or difficult to manipulate quickly—especially during malfunction drills or one-handed operation—this extended variant gives you a larger, more ergonomic purchase point. The design maintains full compatibility with your Glock 42 while adding real usability without requiring gunsmithing or permanent modification.

Constructed from stainless steel with a QPQ (Quiet Quench Process) black finish, this slide lock is built to resist corrosion and handle the wear of regular carry and training. The QPQ finish is known for durability in harsh environments, making it a solid choice if your Glock 42 sees regular use in varied conditions. The extended profile makes it equally useful for range shooters working on reliability drills or defensive training where positive slide manipulation matters.

Installation is straightforward—this is a direct-fit replacement for the factory component, so no fitting or modification is needed. Whether you're running your Glock 42 as a backup, off-duty, or deep-carry option, a larger slide lock can measurably improve your handling speed and consistency, particularly if you're working with reduced visibility or gloved hands during training.
