i only have a p22 now, getting the can in a few months. but need to see if i need to get the shorter barrel or if i can use the long barrel with the adapter. if i like this p22 as much as i think i will i might be in the market for a p99 later. ok shot the p22 today and it shot great. no feed problems at all. had to do some adjusting on the laser, but that is expected. this is realy for my wife but i get to play with it when she gets done. i got it for her to shoot idpa with me (special ok by the head RO for her to shoot with a .22). maybe after i get my fn 5.7 i might just need to add a walther P99 in .40 S&W to my collection. she liked it alot more than her ruger 22/45 so maybe i can get rid of that on a new walther, for her you know.
