Frequently Asked Questions

What are the key internal parts needed for a Polymer80 slide assembly?

You'll need the safety plunger, extractor, extractor plunger spring and bearing, firing pin (striker) assembly, and the back cover plate. Ensure all parts are compatible with your specific slide and frame.

How do you properly install the back cover plate on a Polymer80 slide?

Depress both the firing pin assembly and the extractor plunger simultaneously. Then, slide the back cover plate into position until it audibly clicks, securing the internal components.

What is the recommended method for installing sights on a Polymer80 slide?

Use specialized tools: a Glock front sight tool with a fine-threaded screw for the front sight, and an MGW sight pusher for the rear sight, especially for tritium sights to avoid damage.

Can I mount an RMR optic directly onto the Polymer80 slide?

Yes, this video demonstrates mounting a Trijicon RMR onto a Brownells Window Slide cut for RMR. Proper torque on the mounting screws is crucial for a secure fit.
