The takedown hole in the guide rod allows for easy disassembly/reassembly.

This guide rod does not include recoil springs or spring plugs/reverse plugs, but they can be purchased separately.

Fits flush with the slide so you can turn the bushing (if applicable) to disassemble the gun. This guide rod also features a takedown hole.

The head of the guide rod has smooth beveled edges to make for a seamless look.

Check for fit in 3 areas:
(1) Barrel feet should not contact head
(2) Where guide rod rests against frame
(3) Back surface of slide/dustcover is flat and even.
