Frequently Asked Questions

What are the key steps for installing an ambidextrous thumb safety on a 1911?

Begin with a safety check and disassembly. Fit the safety axle and ensure slide clearance. Relieve the right-side grip for the safety arm. Critically, fit the safety to the sear for proper engagement. Finally, test and adjust tension for consistent operation on both sides.

What fitting is required for a 1911 ambidextrous thumb safety?

Fitting is typically required for the safety's axle to match the frame's tolerances, for clearance with the slide, and most importantly, for the internal stud to engage the sear correctly without movement.

How do you ensure proper sear engagement when installing a 1911 thumb safety?

Carefully file the safety's internal stud until it perfectly blocks the sear when the safety is engaged. This is a critical step that requires precision to ensure reliable function and safety.

What adjustments are made for the 'snappiness' of a 1911 thumb safety?

If the safety feels too stiff or 'snappy,' a Dremel tool can be used to slightly adjust the detent face on the safety. This ensures consistent and positive engagement and disengagement force on both sides.
