Precision Extended Slide Lock for G43/43X/48

$14.99 to $29.99
SKU: 1108
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.

Clean your pistol


I love this part it dropped right in with very little work my G43 is so much easier to clean now thank you Glock Store

Nice product.


Fits nicely and makes it much easier to break the gun down for cleaning. Also it doesn't interfere with my holster at all. Worth every penny.

Working real good


Love this upgrade, one of my top five upgrades and easy to install and looks tremendous in stainless, grab the stainless pins to while you're here

Note: Doesn't work with LaserMax recoil spring laser


I'm giving the product a 5 for the workmanship. It just didn't work for my application. I have a LaserMax LMS-G43 Guide Rod Laser installed in my Glock 43. This requires the slide lock to be able to be pushed to one side or the other to turn the laser on. After putting the GlockStore slide lock in I found it would not move from side to side. I'm holding on to the part in case I ever retire the LaserMax.

Love the videos. As a novice I was able to install +2 magazine extensions and TRUGLO TRITIUM/FIBER OPTIC SIGHTS. Look forward to visiting the Nashville store.
