i'm no pro but i'd say recoil would be the same, though you -might- get a little more muzzle rise. i don't think it'd be an issue, though. i think the bigger problem would be..
accuracy -may- decline since you -may- not have as full a grip. most people have some accuracy problems if their pinky hangs off the grip. if you can fit all 3 fingers on it though, comfortably, then i'd say go for it if it's what you want.
