I've had two Tomcats -- the second came after the first was replaced under warranty. After many repairs, I got it fixed again, and traded it in on a Kel-Tec P11.
The P-11 isn't really a pocket gun, but you CAN carry it that way if you are big and have big pockets. But get a pocket holster!
The P-11 is a much better gun than the Tomcat, and most of the tales about unreliability with the P-11 is residue from the early years. They've made great leaps in quality control in the last couple of years.
I "fluffed and buffed" mine following the instructions ont the
WWW.KTOG.ORG (Kel-Tec Owners Group) website and it has never missed a lick in thousands of rounds.
If your choice is between the two, then its a real no-brainer.
(That said, the P-11 is a difficult gun to shoot well; its easy to shoot accurately, it easy to shoot fast; its hard to shoot fast and accurately. You'll need to practice a LOT.)
S&W '59 series (15 round) mags will work in the P-11, and you can get a small plastic spacer from Kel-Tec that makes the longer mag, in effect, a grip extension.
I much prefer the 9mm round to the .32 acp.
(All of this praise for the P-11 is offset by the fact that I've put mine in the gun safe and now carry a Star Firestar Plus [alloy frame]. Its about the same size, about 8 oz heavier, can't be carried in a pocket, but is much, much easier to shoot well, quickly. I picked mine up in a Pawn shop in like-new condition for $129. I've even had top time in a local IPDA match with it -- something I couldn't come close to doing with the P-11.) The P-11 will eventually be sold or traded. But its still a darned good gun.
