Rell, are you talking about the "Deerfield" introduced in 2000 or 2001, or are you talking about the older Ruger 44 introduced in the 60s? The old ones had a tubular magazine and the new ones have a 4 shot rotary magazine.
I suspect it's the early model because I don't think the Deerfield (a meni-14 on steroids) had been made with a Mannlicher stock.
Correct me if I am wrong please.
