Pro-Tip: Don’t Cut 90 Degree Corners in Your Slide

Just something to be aware of. 90 degree corners come to an infinitely small point. You may not be able to see it with the naked eye? But it’s there. 

And that sharp 90 degree turn creates something guys smarter then me call a, “stress riser”. Meaning…as recoil impulses flow through the slide, they can peak at that 90 degree juncture. Which in some cases, on a micro-level, forms a crack. 

Don't cut 90 degree corners in your slide.

OEM Glock 34 slide. Notice the slide cut window is actually rounded at the corners? That is on purpose.

Once that crack starts, it’s likely to spread. And left to run long enough? Can lead to a significant failure as the crack migrates across the part. 

“But Marky, X gun has ninety degree cuts from the factory”. Yes, that may be true. And those same cuts were put there by engineers, who are covered by their companies’s OEM liability insurance, which is also backed up by some kind of limited or full warranty. 

Don't cut 90 degree corners in your slide.

I believe this is a VP9 slide. Notice the window corners are also rounded. On Purpose? Or maybe just lucky? Regardless, that is preferred.

All I am saying is there are a lot of “custom” handguns floating around with unqualified and untested mods that do lead to cracks. If you have one of these pistols, but put more miles on your car than rounds through your gun over any 12 month period? Your gun will probably be fine. 

Or it may not?
