Anyone own a Glock gen 4?

I have 3.... a 26, 19 and 34. I've had a couple of stove pipes in the 34, but it was out of one box of ammo so I think it had a few bad loads in it. At the time, it also had the older style ejector and since being replaced it's been fine. I've put around 1500 rounds through it. On the 19, I had a couple in the first 200 rds, but I now have around 700-800 in it and it's been good to go, so I think it was just a break in period. My 26 hasn't had the first problem, but they didn't change any recoil springs in the subcompacts. My advice if you get one, would be to buy some hotter ammo to run through it for the first hundred or so rounds.

I have a 23. Had it about 2 months. I like it a lot. Havent had any problems and put about 300 rounds through it.

I do. The original recoil spring was stiffer and actually resulted in even less recoil. It was changed due to people using lower powered ammo to train/target shoot. This caused the stovepiping. I believe the old spring was stamped 03. The new spring is stamped 04 like this one:



Neither should give you any problems with duty load rounds.
