I have a Gen 3 Glock 22 .40 cal that I'm convinced would shoot lead musket shot if you found a way to cram it into the barrel...lol. I've retired the handgun with full honors into my gun closet. I bought it in 2000, and I've NEVER had it jam after thousands of rounds. I used it for IDPA competition for a lot of years, and it's been meticulously maintained but iti's all stock except for the sights. It's just a tough gun. I've since branched out to other types of handguns but I fully appreciate and respect Glock pistols.i have a CZ 75B, 9mm, it does not like steel case (Wolf) ammo.
i have a Remington R 1911 .45ACP, it does not like Blazer brass ammo
my G3c, does not like reloaded ammo. (from a very reputable reloader supplier in my area)
my Glock G-17 4th Gen, eats anything and everything and begs for more.
so yes, many times, some guns just do not like what we feed them.
