Saw other posts here but haven't seen an answer yet, or I'm just a n00b looking in all the wrong places,... but I have this problem with both of my and my wife's Glock 17's: Is it OK that the edge of the striker pin channel seems to be "mushroomed" over, as in the following pics? Both guns seem to function adequately, and I can't push the pin down to make the striker protrude when I have the slides off. Any info would be appreciated. Thanks! Here's the pictures and weapon info: Striker Pin from Glock 17 G3, S# DRM###, 2000 era: Striker Pin from Glock 17 G2, S# BMR###, 1995 era: (OOPS! Needs cleaned!) Both purchased used / local armor, reportedly trade-ins from some type of LE academy. Thanks in advance!
