5" stainless, and adding adjustable tritium night rear and fiber optic front, along with a TLR-6 lazer and flashlight. Had two holsters made, one for the lazer and one without, from Simply Rugged---Rob does beautiful work and reasonable.
Normal sights will be sighted in for 230's and lazer for 185's.
Will pretty much retire the SS 4" Security Six I have carried for the last 30 years
