Never been a big KelTec Fan, but when I worked in the Wholesale Firearms Industry, I won a little KelTec P-32 that they made me with a silver slide & bright blue frame. I dubbed it my Dallas Cowboy Saturday Night Special.
Ive carried it for over 10 years, always loaded with the Corbon +P+ 32 acp ammo.
I generally shoot out my carry ammo every 6 months and clean out all the pocket lent. Fired over 300 rounds to check reliability before I ever carried it. It's been like the Energizer Bunny of 32acp's and has never failed to fire or feed once.
It's not a handgun that I would ever carry as my primary or ONLY CH gun, but gets carried a lot as a BUG when I wear my Sunday Go To Meeting clothes.
That being said, all of my buddies that bought KelTec P-3AT's all had several issues and some made multiple trips back to the factory for repair. I've never owned one in 380, but if I was buying a Micro .380, it would Definately be a Ruger LCP. I've had numerous students in my CHL Classes quailify with the little Ruger, and they seem to function flawlessly.
Would I buy Another KelTec. ? Probably not, unless I replaced my P-32 or my PMR-30. Both of those model KelTecs function flawlessly for me. Here's a pict of my little Dallas Cowboy Special.
