With regard to recoil:
Its not an issue: I can tell no big difference between it as my S&W 669, Sig P210, Luger P-08, or Glock 17. (Well, maybe the Glock 17 is a litle lighter -- but Glocks are known for light recoil.) Any snub-nose revolver is much more harsh. I have never found it unpleasant, even when shooting it a lot.
Most smaller guns, such as .32s (like the Beretta Tomcat, the Seecamp, a Walther PPK, or my CZ-50 etc.) are much more difficult to handle and have substantially more unpleaseant recoil.
The design of the Kel-Tec P11, coupled with the polymer/aluminum frame, seems to do a good job of managing recoil. It is NOT a problem!
