Kel-Tec experience.
I bought a new Kel-Tec P3AT a few months ago.
Day 1: took it apart, cleaned it, lubed it.
Day 2: Range, 50 rounds, many failure to both feed and eject, took home, did fluff-n-buff, and recleaned/lubed.
Day 3: range, 30 rounds, better but still problems...and on round 31 that day, the slide seized in the back position.
Well, shipped it back to Kel-Tec. They wanted to know what ammo I was using and what I intend to use when I carry. I told them Hydro-Shoks to carry, they said they'd test fire with ammo of my choice and get it back to me within 3 weeks. Well sure enough, just short of three weeks, the gun comes back with new barrel and slide and works 100%. The more I use it and it breaks in, the better it feels too. Kel-Tec customer service was great.
The point is...if a Kel-Tec is what you want and the minor fluff and buff doesn't cure any ills it comes with, Kel-Tec will do their magic and make it perfect for you.
My other choice was a Kahr PM-9 but didn't buy for two reasons: One was money, was too expensive. Second was I just don't trust Jason Moon, his family history and where Kahrs money goes.
Anyway, the local range I go to...all the guys that work there open carry and all have Kel-Tec P32's as back-ups. They say the .32 is more reliable. Another idea is there is a gunsmith/plater ...I think he's in Texas, last name is Fuselier, does some amazing things with Kel-Tecs: bead blasting, plating, fluff-n-buff. People who've had him work on their guns say he's a master and does great work.
While my Kel-Tec was away, I looked at other small guns as another possibility and got a chance to fire a few North American Arms Guardians. I shot the .32acp, the .380 and the cool .32NAA round. All of them worked flawlessly. Great little guns. Are metal so heavier than the Kel-Tec but small and reliable. Just chucking another possibility out there.
