Precision machined for the Glock 43.

This is NOT STAMPED like most other slide locks on the market.

This allows you to be more accurate shot to shot!

Our GSPC Precision Extended Slide Lock is machined to be thicker and more robust than the factory part and is guaranteed to deliver better accuracy by letting your barrel and slide settle into battery more consistently.

We machine this precision part here in the USA from 416 stainless steel that is hardened to 45 Rockwell. It is slightly longer than the factory part, which makes it easier to grasp when removing the slide for disassembly and cleaning.
