NoteThe Cross Armory Slide Lock fits Gen 5 but is also backwards compatible with all Gen 1-4.   Gen 4 and previous generation Glock slide locks will not work with your Gen 5.  Many websites are incorrectly listing older generation slide locks as “Gen 5”, so be cautions when you purchase from other websites and take note of the shape of the Slide Lock in the pictures.  We want to make sure that what you buy for your Glock Gen 5 is the correct part, wether you buy it from us or somewhere else.  See our photos that highlight the correct size and shape of the Gen 5 Slide Lock.

The Cross Armory Extended Slide Lock features an extended, but not protrusive design. Will complement your Glock Gen 1-5 and/or P80 functionally as well as aesthetically.

We designed our own extended slide lock because we wanted to offer Glock & P80 enthusiasts a quality machined extended slide lock to go with our other Glock & P80 products. 

The Cross Extended Slide Lock is made from 4140 Ordnance steel and carefully surface treated for corrosion resistance.  We have improved the geometry to make the install time minimal, finger response optimal, with increased strength and reliability.

The Cross Extended Slide Lock will drastically improve slide removal for cleaning and maintenance work, a necessity for any Glock/P80 enthusiast looking to improve their weapon.

If you have a Gen 5 Glock, and are shopping around…be sure that the slide lock you buy is made specifically for a Gen 5, as our parts are.  There are specific shapes to look for, that you will see in the images that are different from previous generations.  Many websites are selling incompatible parts made for previous generations,  that could cause your Gen 5 Glock to malfunction.  The main indicator of a compatible Gen5 slide lock is the angled cut at the top that allows for the part to fit between the barrel lug and the recoil spring rod.  There are other areas to look for as well, see the image comparison to be sure you have a slide lock that is made for Gen 5 like the Cross Armory Extended Slide Lock.  Weather you buy our parts or from somewhere else, we want you to be sure you get the right part for your Glock!

    Another great upgrade from Cross Armory! I know the description says extended but I would describe it more as “enhanced”. Like the description says it fits all holsters just like the factory slide lock but it is cut at an angle which makes it way easier to use. Definitely a worthwhile upgrade and it’s available in all the cool colors too. Check out my YouTube install and range review for the full details about the enhanced slide lock! https://youtu.be/PENVB-dkk7Y?si=wLK7DV1lxpbzGitA
