I'm pretty sure Robar is your best bet for that, if I'm not mistaken they are located in Phoenix.
But its a cheeseburger...why wouldnt you want to buy it
I heard that from one of the guys at Glockmeister, as well. Gotta get on that... once finals are over.
I have a friend who had an ambi mag release G21 and was also having problems with it. He called Glock and they replaced it for free. I've heard they'll do that for anyone who calls them with an ambi mag release model as they know they don't work right. I've heard others that complained enough on the phone and were able to get Glock to give them a Gen 4 G21 as replacement.
Can I give you all of my .40's brass ?If he doesn't want it, I'll take it.
