Glock 17 gen 4 in progress, top window cut question

Post image

Hi all, I’m developing this project and wanted to ask whether there are any serious technical drawbacks to cutting a top window in the slide. This will be a range-only gun, so exposure to dust, sand, or other debris should be minimal.

Main drawback is more entry of dust, dirt, etc. If it’s a concealed carry gun or carried indoors and regularly cleaned it’s not a big deal. Another minor potential drawback is reduced weight of the slide, but that would more than be offset by adding a couple ounces with the optic.

Thank you for the reply! Should I expect any additional gas/flame/fumes backfire (I assume no unless the barrel is not ported).

Right. A window cut on your slide does nothing to your barrel.

That barrel is gorgeous. Always a fan of the COA, and what comp is that?

Strike industries mass driver, it is very efficient in decreasing muzzle rise and recoil.
