No trouble from the Glocks, or from the Rotties? I've had to do some minor parts replacement, but as with the M1911A1 .45, every component part of a Glock can be removed and replaced without tools [okay, some folks count the Glosk factory pin puser as a *tool,* but it's certainly not necessary]
If it's a half-dozen trouble-free Glocks you've got, it sounds like you're in good shape, as I am with my 17. But if it's multiple obedient and well-behaved Rotties you have, let me know if you're ever blessed with pups....

My first experience with the glock was in Quito Ecuador. A SF troop was packing one as he liked the no rust option that glocks seem to enjoy from good tough finishing process. I have actually been to the glock USA facility in Smyrna GA and was given the nickle tour , dinner and a great ride in one very nice custom porsche Mr Glock had given his CEO there. Mr Carl Walther was CEO of that place then and when my team and I went to pick out and pick up our order we got to break bread with Carl and his wife.
If I'm not mistaken he has since went to Ruger and then was with Steyr and now GSI in Huntsville. Glocks are great duty guns IMHO and take more abuse than we could dish out. I prefer the 1911 series for my personal use but if a High Capacity , reliable sidearm is needed the Glock is right up there with my SIG 228 . If I know I'm gonna get wet and muddy I'll take the glock everytime as it is just a rugged simple piece of gear. The P38 C-Rat opener of pistolas IMHO.......
Stay Safe !
