Went to the range today with friends. Got home and set everything out to clean and found this:
One for the Milk Carton: My Glock 19 Gen 4 Slide Lock | The Truth About GunsThe Truth About Guns
The slide lock lever on my 19 is missing. Can't find it in my range bag or anywhere in the house so it must have happened at the range. Ordering a few replacements now since they are cheap. Looks like it's an easy fix.
