A strange lookin', kinda short cowboy named Elmer Keith figured this stuff out for us a few years ago. The most ballistically efficient barrel length in .44
Magnum is 8 inches, or as close to that as your favorite maker offers.
8-inch barrels provide a very useful sight radius if you are limited to iron sights. My S&W 24-3 is a .44 Special target revolver with a 7-inch barrel. As a bullseye gun, it is very efficient. I used an 8-inch Redhawk for hunting, plinking and target shooting for 25 years. Sweet gun! --bought another just like it for my son last month. If it loads, the thumbnail shows the boy's $500, used Redhawk.
I did shoot a few thousand magnums when firing metallic silhouette matches but the vast majority of the rounds fired through my .44s have been Specials. I have two S&W Model 21s with 4-inch barrels, along with a 4-in Dan Wesson. These are most pleasant with .44 Specials. Any .44 feels better than a .357. .44s "thump", .357s "crack". ALL are accurate revolvers. The short ones are great for plinking, 50-foot bullseye and defense. The longer ones are better at bullseye, still fun to plink with and better suited for hunting.
Yeah, lots of choices. . . . You just have to decide what you do the most of and select the barrel length that provides the best utility for your needs.
I bought several.
