tbk405,
Welcome to the forum! do you handload? the real old 444's are a better gun then the newer ones, there are a few differences between the older and newer that you may or may not like.
The original 444's with the 24" barrel, barrel bands, narrow hammer, good trigger, buttery smooth actions, honed chamber and of course the high comed buttstock that was in a straight stock config with 1-38 twist barrel with Microgroove rifling, the very early models had the rounded lever, then in around 1970 they went with the square lever. They did make a model with a 22" barrel with barrel bands, I'm not sure what else it had.
The newer models had a 22" barrel, wide hammer, worse trigger, forearm bands, courser action, normal as today buttstock that was in pistol grip config and the 1-38 twist Microgroove barrel, IIRC it was a 444S model, the S was for "Sporter" then the added the cross bolt safety and called it a 444SS.
Then the latest models were had in either a 18.5" or 22" barrels (18.5" was the 444P) (the 22" was the 444SS)
they were the same as above but, except the 444P had a straight stock, both had the 1-20 ballard rifling.
