1) About 20 years ago, I had a first gen 17 and a couple of 19's.
2) Went back to a Colt Commander.
3) The 17 had a reoccurring problem with the trigger not letting off when pulled, even after multiple trips back to Glock and having it declared fixed.
That 17 and how Glock treated me at the time with the repair, soured me on them for a long time. Took me about 20 years, but Ive since got over it. After getting tired of fiddling with the 1911's, and a short stint with SIG's, I went back with Glock, and they now have pretty much replaced all but a few of the others.
