.44 is a bit underrated as a Deer cartridge. I used to own a Ruger semi-auto(Deerslayer) in that caliber and it laid the smack down on Bucks
I never had a bit of a problem with mine.
Mine works very well too... I keep saying, "one of these days" i'm going to get it out and harvest a deer with it as i haven't for a long time now...
