...........until you freakin lose them! In all my years of owning Glocks today was a first. I actually dropped the stupid things and man did they get gone. Took me twenty minutes on my hands and knees to find both of them. I was even putting my face flat on my cheek against the floor with a 190 lumen light looking for them at one point doing full room floor sweeps. Stood on a towel and gently shook my clothes etc etc etc. 20 minute nightmare but I found them. Advice, don't go screwin' around with your striker spring cups over hard wood floors. They tend to bounce like tennis balls.
