I've been out of circulation these past few days and don't know if this has been mentioned yet. Was checking out Davidson's and noticed they had a new Taurus 22LR/22mag I haven't heard of. The 22lr is the 990 and the 22mag the 991. Both are 9 shot with ribber grips. Looks like they will be available in 4" and 6" versions in either blue or stainless. Is this the replacement for the 22 Tracker or an additional offering?
