Rival Arms RARA80G004A Extended Slide Lock Glock 42 QPQ Black

The Rival Arms RARA80G004A Extended Slide Lock transforms Glock 42 operation with enhanced leverage and positive engagement. This precision-machined component eliminates fumbling during slide manipulation and magazine changes. Built from QPQ-treated stainless steel, it delivers consistent performance across thousands of rounds.

What Makes This Different

The extended design provides 40% more surface area than factory slide locks, creating positive tactile feedback even with gloved hands. QPQ (Quench Polish Quench) treatment penetrates the stainless steel substrate rather than coating the surface, preventing wear and corrosion. Unlike basic aftermarket alternatives, this component maintains factory tolerances while improving ergonomics.
