    I was looking at a new model G20 the other day, and I mentioned to the shop owner that I have a 1992 model G20 that I really like. He was telling me something about Glock will do some sort of upgrade on it for free. Does anyone here have any info on what they do to them? and will it affect the great trigger pull on mine that is like no other glock I've ever had? Is it something that really needs to be done? The dealer didn't really know the details, he just said that anytime I heard of a show where the factory glock armorers will be, To take my pistol to them, and they would do the modification for free.
