Not the Kel-tec P11
While I like the Kel-Tec, it's not a good replacement for the G-19
Yes it is measurably smaller, but just about as thick which negates any real improvement in carry comfort. That width does have a redeeming grace tho, makes managing the recoil of full house 9 mm easy in such a compact package.
I may go with an LCP, just for comfy pocket carry. I have shifted my carry position (IWB) to between 2-3 O'clock and it's a huge improvement, esp. sitting down in the car.
The price is right and with a fluff and buff the P11 is a solid little pistol. If you go Kel-Tec Google up Keltec fluff and buff and have at it. Mine was a jamomatic and the fluff and buff fixed it 100%. I'm told a couple hundred rounds down range will fix it too. I did not keep mine long enough for that.
