Is there any ammo that i should stay away from with regard to my new p3at? In other words, i am learning that some ammo is hotter and I know the Kel Tec is not a heavy duty gun, so if there is some ammo that i would be better off staying away from, I would appreciate your input. For practice, i will shoot a variety of less hot/less expensive loads, but for self defence, I want a good powerful load, but not something that is damaging. I saw a load at a local gun shop that specifically says "don't use in kel tec p3at".
