Polish pps 43c 9mm help

[HillbillyPyro]

So I've had this from classic firearms for about 2 years. It had jamming problems since the day I got it. I've researched and researched and have found that people say to either shim the back of the spring or to dremel the election port out. I've done both. It's a lot better but still jams! Anyone have any experience? I've dremeled about .060 thousandths off the bottom of the port and put a quarter inch rubber shim behind the spring. It does better with high velocity rounds as it was made for, but I'm frustrated. A buddy of mine got one at the same time and hasn't had an issue yet. I did add some gun grease to the bolt as well.

I have to ask, do you fire 9x19 or 9x18 rounds? Maybe it needs to shorter rounds?

I've just been using whatever 9mm I can find. The sellier and belloit, and magtech seem to be working best after my mods. Ran 30 rounds yesterday and only had 2 jams. That's best I've ever gotten out of it

I was told at the gun shop to try hotter rounds

Thats wickedly cool!

Do you reload? Might help to tailor a round just for it. Might want to try double tap or Buffalo bore for hotter ammo

 

[luckysaturn13]

Is your buddy shooting the same ammo?

If memory serves; those like to be run wet. Try replacing the gun grease with gun oil and that might just increase slide velocity enough to get reliable extraction.

My buddy has never had one jam and it'll eat whatever he puts through it.
