I purchased a Glock 19 about 18 year ago, ( used at that time, LE turn in). I know that I had ran about 8000 Rounds through it over the years and yes there were a lot of hand loads during that time both lead and jacketed . I noticed it developed a crack in the frame above the trigger. I gave Glock a call last month and they said send it in and they would fix it up. I asked them about what the charge would be and they said they would let me know after looking at it.
Well this is a list of what it needed. Its a long list.
Inspected; Replaced Frame, Locking Block, Pins. Trigger assembly, Slide stop Lever, Magazine Catch, Side Lock Spring, Extractor,
Firing Pin Assembly, Reassemble and Clean. Meets factory Specs. Total cost with shipping. $ 00.00.
What can I say I am a happy shooter. That is a lot of work for no charge. This Glock is my main carry gun and I have felt naked for the last six weeks. I know that's not a pretty thought.
Well if the rain and snow will stop tomorrow, I will take it to the range so we can get to know each other again. Ill never talk down about Glock

P.S. They returned it in a new case also.
