I live about a mile from Glock. A while back I bought a glock at a local gun shop. Not having any gun knowledge I just asked them for something cheap. It so happen that the local police turned in their guns for new ones. I asked the salesman what i should do if there is a problem with the gun. The salesman said just bring it to Glock as it is guaranteed forever.

I brought the gun to Glock as soon as I purchased it and asked them to check it out. Three days later they returned the gun with 90% of the parts replaced. No charge.

Can’t complain about that
