For precision, consider upgrading to night sights or a red dot with a compatible mounting plate. An optics-ready Glock 19 Custom slide requires a proper mounting solution and a co-witness plan with your sights. Ensure the optic footprint won’t interfere with holster compatibility and is installed by a qualified gunsmith if needed.
Trigger Options for the Glock 19 Custom
A smoother, consistent trigger pull can dramatically improve shot-to-shot accuracy. Options range from softer springs to aftermarket connectors that maintain safe operation. Always verify that any trigger upgrade preserves the firearm’s safeties and reliability, and consider professional fitting if you’re unsure.
