The problem is more likely to be your technique.
Small pistols are very difficult to shoot well.
You have to hold them in a death grip, with rigid arms, and not relax or flinch.

Your little gun needs every kinetic ounce of recoil force, in order to function properly.
If you flinch or relax your grip, the gun will malfunction because your hands and arms are absorbing some of that necessary force. Typically, it will fail to eject properly.
The P3AT we own is not ammunition sensitive, but it is technique sensitive.

good cleaning and lube cant hurt either.... lots of people try to shoot right out of the box and it leads to issues.... what steve said first, then what i said... then everyone elses advice.

Thanks fellas. I am new to these small semi autos and had no idea. Going back tomorrow and give it another try.

...And you could also polish its feed ramp and chamber, if you want to be really, truly, absolutely sure.

My P3AT did not like certain ammo at first, like the Winchester White Box, but after a few hundred rounds it has smoothed out.

mine eats anything but I did polish the feed ramp after I bought it.

Mine hates WWB but handles HP stuff just fine.

Try some of the MagTech ammo. They make a nice 95 grain FMJ round that is the only make that will function in my Kel Tec and my I.O. Hellcat pretty much all the time.

What process do you use to polish the feed ramp?

See my PM, sent tonight.

I have a P3AT and it's been a jam-omatic from day 1. Cleaned and did a fluff and buff per the KTOG forum before I ever took it to the range, put close to 200 rounds thru it between 2 trips to the range, had failure to feeds and stovepipes. The most consistant problem was always the last casing would fail to extract on multiple(3 different) mags
Sent it back to KelTec, took it back out and except for 1 stovepipe, got about 1 out of 10 rounds failing to feed from the same 3 different mags from 70-80 rounds. Getting ready to send it back again. I really wish I'd picked up a Kahr CM9 in hindsight, but couldn't find one and figured for the money how could I lose.... I've never had to expend more rounds trying to break in a pistol.

Does anybody recommend a Ruger LCP over it? THinking about keltec but its posts like these that make me stray away despite their amazing price point and lifetime warranty

To me, this sounds more like a failure of technique than a failure of equipment.
Tiny pistols are very hard to shoot effectively and well. If your technique isn't just about perfect, you will experience failures to extract and extraction/ejection-based jams.
Really bear down on your grip, and keep your arms really rigid. Don't relax anything, while you're shooting the little beast. That may correct your problems.

Did the KTOG "fluff and buff" include polishing the feed ramp and chamber?
If it didn't, you might want to try it. It really helps smooth out the gun's function.
(If you want instructions, send me a PM.)

I purchased the P3AT to have an additional carry 380. I have 2 LCP's that I have run appx 200 rounds through each one without one problem on either gun. My P3AT was sent back to Kel-Tec 8 weeks ago because after appx 150 rounds with a 60-70% jam rate, I had had enough. Hope to get the gun back soon and will give it another try.
