Current Production

The model 22 was re-introduced as the 2nd limited production Thunder Ranch revolver in 2007. This gun features a 4" match barrel with under lug, fixed sights, coccobolo grips, and an internal lock. The popularity of this revolver led S&W to continue its production in its classic line as the 22-4.
