So what I'm hearing so far from other posts, your on the right track with the 44 mag for deer. Now go out and find one that when you pull up the revolver (or are you thinking Magnum Reasearch ) the sights line up and most importantly the trigger feels excellant! I hate the big box store but when Sportsmans Warehouse was open I had my choice of 3 Red Hawks and I picked the one with the trigger that broke the cleanest. Trigger is as important with handgun as with rifle!!
S&W, Tarus or others you have the right caliber for N/A big game, now find the gun that fits you, it needs to feel comfortable/natural. I did a lot of dry fire before things worked out on targets, I was anticipating recoil. A scope with at least 2x will help show you your errors. Before deer season I bet I do at least 100 dry fires over 3-4 weeks and it is amazing how much I learn and I consider myself a decent handgun shooter (although that is sometimers debated with the boys and myself /ubbthreads/images/graemlins/laugh.gif)
Buy it, then go out and find the load that (if you hand load, I found the Speer Gold Dot 270 was awesome) that puts your skills as a handgun shooter to the test. 50, 60 , 75 or 100 yards are up to you!
Keith Will be proud!!!!
