Just received my issue of Gun Tests magazine and there is an small paragraph on the recall of 22a.. Article says pistols made from Aug. 1, 2008-Feb 19, 2009, may have certain slides that don't meet design specs.This may create a lack of head space, and unintended discharge. Pistols that have serial numbers UBW 0000 - UBW 9999 ; also UBY 0000 - UBY 4104. Contact Smith and Wesson or Email address 22A@Smith-Wesson.com for further info. Just thought I would let everyone know if they didn't know allready. This article is in my Aug. issue of Gun Tests. Hope this helps.
