I suspect that this is a training issue, rather than a firearm issue. Replacing the magazines is a common manufacturer “feel good” measure.
*ALL* semiauto pistols can and will do this if you use them improperly. Including the 1911, Springfield XD, HK USP, etc., etc.
Good reason to use a revolver.
That is the correct answer. And to the OP, if you think a GLOCK is an expensive pistol you don’t get out much.
A stovepipe incident is the easiest jam to fix. Sweep your non dominant hand over the top to clear the empty casing. Also, revolvers dont jam as autoloaders do, but you are limited to 5 or 6 rounds. But if your barrel on a revolver is not clean, your accuracy will suffer. Brass tacks, regardless if it is a saturday night special or a Desert Eagle, they need consistant care. If you take care if it, it will take care of you.
You are correct. Cleaned and properly oiled is the solution. A stove pipe is caused by the cartridge only partially ejected. Oil the slide frame and you don't have a problem. Typical police problem. The only time most of those guys check a weapon is on the way to qualify.....red
