I need to give kudo's for exemplary service I received from Glock. By background here is my earlier thread explaining challenges I had with my Glock 36 pistol: https://www.glocktalk.com/forums/showthread.php?t=1472575 I brought the gun up to Glock. To make a long story short, a Service Tech checked it out, shot it and after several go rounds of trying to reproduce the problem I met with him and his boss. While they found the gun initially functioning fine they were able to reproduce the problem. It only occurred when they (like my natural grip) gripped the gun not flush at the very top of the frame/backstrap under the slide. My position that I communicated to them is that I would expect these problems with a lesser gun but not a Glock and that I was very disappointed and would need to sell the gun (with the appropriate disclaimers for a new buyer)as I could not depend on it for a defensive gun. The tech's boss then offered to swap out my gun. He asked which type of gun I would like. I told him something similar in size and caliber. So I ended up leaving with a brand new Glock 30S. That to me is extraordinary customer service, a rarity these days. I am a very happy guy and look forward to trying this bad boy out over the weekend. Thank You Glock!!
