I'm thinking of getting a new range toy and have been looking at .22 semi auto's with a rail. Looks like my options are the m22(glock clone), Sig Mosquito or the Walther P22. Anybody have any experience with any of the three? I was fondling them at Wholesale Sports and the Sig was $350 and the M22 was $250 with the Walther in between. The Sig had the best fit and finish but the price on the M22 is pretty attractive. Not sure which to go with.
