I do pay attention. I look through the sights of my G34 and look at all the 1911 jams and just quietly laugh.Lol, I see it all the time.
Go to any USPSA, steel challenge, or 3 gun match where competitors are known to use aftermarket products. 90% of all failures at the matches are from Glocks that have been messed with.
Maybe you should actually pay attention when you're at the range.
