So I picked up a g26 in a trade not too long ago. Just took it out of the safe to mess with it a bit and I had an issue. When I put an empty mag in and rack the slide for some reason the slide is not locking back. I have owned numerous glocks and have 6 others sitting in the safe right now, none of them have ever had this problem. Would always lock back with an empty mag in. First I thought it was a faulty mag but it happens with any mag I use. Then I tried switching out the slide stop and that wasnt the issue either. I have no clue whats wrong with this thing does anyone have any suggestions? Im about to put my head through the wall..
