We all like the decorative slide cover plates. The ability to put your favorite logo or saying on the rear of your Glock slide is the coolest thing ever. Or is it?
Recently I installed one on a customer's gun that he obtained from a vendor on Ebay. The fit was pretty poor. I had several others in my inventory so I measured them as well. They were from several different common gun part suppliers.
Seems that the makers of these aluminum cover plates have little to no regard for the proper dimensions to fit the slide cuts. The factory slide plate fits snug and offers no inclination to fall out. The part provided by my customer actually could be slid down about .030 with just the friction of my thumb. During test fire prior to returning to the customer, the decorative part actually locked up the gun. The part slid down, hit the rear of the frame as the slide traveled forward and prevented the slide from returning to battery rendering the gun inoperable. Needless to say I refused to install said part. I re-installed the factory Glock part and admonished the customer to discard it.
When compared to several factory slide covers, all these aftermarket slide covers appear to be .015 to .020 too thin in the flange area. They are .010 to .015 too narrow. The recess is .005 to .010 too shallow. I checked samples from 3 different vendors. All were undersized.
I would advise that all users examine the fitment of the slide plate with the striker assembly and extractor rod assembly removed. If the slide is sloppy as heck you must realize that it relies on the spring tension of the striker sleeve to keep it seated. the factory slide cover plate is a rather snug fit in every direction. I'm not saying you all need to junk them...but it sure deserves inspection if you use your Glock for personal protection.
