10mm vs .44 Mag for woods carry — what the ballistics actually show
I've been running a G20 as a backup on longer hunts and got asked recently why I didn't just carry a .44 Magnum revolver instead. Fair question. The ballistics argument isn't what most people think it is.
On paper, a hot .44 Magnum load (like a 240gr at 1,500 fps) will outrun most 10mm rounds — more energy, deeper penetration in gelatin. A G20 with quality ammo (180gr at 1,200 fps or so) sits below that. That's true and I'm not arguing against it.
But field conditions don't care about laboratory numbers the way we do. A .44 revolver carries five rounds. A G20 carries fifteen, and you can reload in seconds without breaking cover or fumbling with a speedloader in cold weather. I've never needed more than one shot at game, but I've needed to have rounds available in situations where I couldn't predict what was coming.
The .44 also requires you to shoot it well. Most people don't. Recoil is honest and fast. The 10mm is softer, flatter, and easier to place accurately under stress — and in bears or big predators, shot placement beats raw energy every single time.
Legal landscape matters too. A .44 revolver in your pack on public land raises fewer questions than a semi-auto pistol in some jurisdictions, even if they're technically equal. Know your local regs before you decide.
The real answer is: what will you actually *shoot* in a crisis? A .44 Mag is objectively more powerful. But power you can't deliver accurately or quickly is theoretical. The G20 is easier to deploy, easier to reload, and you can shoot it well after practice. That margin — the human factor — is bigger than the ballistic difference.
What's your specific use case? Long backcountry sits, or more mobile hunting?
