Note I am not knocking anyone using youtube to learn how to do something with a Glock or any gun. I know there are people who use youtube for learning how to do things with Glocks and have succeeded where this guy failed. I am not knocking those who do that. I was talking to a gunsmith I know and he mentioned that someone brought him a Glock that someone messed up trying to follow a youtube video. In this case the solution was just a simple replacing of a part. This issue had to do with a trigger job where he was trying to drill and dremel into the trigger bar. This is not the first time someone brought him a Glock with a "oops I did something to my gun and now I have a problem". It got me thinking how many people have had youtube help them do something to their Glock and how many have made a "oops"? Wanna kill these ads? We can help!
