Nice!
Being a newcomer to Rugers:
This is for the 'old' model Vac., not the NMBH/Vac. series, right?
How about the Montado hammer into the NMs, should be similar to what you have done here?
The pictured guns are "old" Vaqueros...the large framed ones. The ones with the Eagle checkered Gunfighter grips are .44-40s (non-consecutive pair). The ones with the elk stag grips are .45 Colt (again, non-consecutive pair)
I have converted a set of the New Vaqueros. I bought a consecutive set of Montados with 3 1/2" barrels when they first came out, and liked them. Now I've gone back and put Super Blackhawk hammers in the consecutive set of KNV (Stainless New Vaqueros) revolvers I've had since they came onto the market.
That makes a total of four guns I've converted...two New Models and two "old" models. The Montado hammers are checkered, where the SBH hammers are grooved...otherwise they appear pretty much the same.
