The Matte finish has been around several years under different names
Uberti offered the Millennium, 12-14 years ago .... US firearms had the Rodeo and the Rodeo II
( USFA even tried 4 color variations tan, OD, black, and mustard in matte "Fail ")
Filli Pietta has their version....
As far as the Smoke Wagon in 44 spcl., I'd call Sue and ask, I'm sure she could pick you a pair of Cattleman, New Models in 44 Spcl.
and have Cody Conagher tune them...cost would be about the same and you have your 44 spcl.
Or Try Longhunter.... they are all Uberti's
If you are looking at Cimarron (Uberti) , I'd suggest 3 B shooting Supply ( Brian Buck )
