Can't go wrong with a .45: it's worked flawlessly for over a century and it puts 'em down.
I climbed Half Dome 10 years ago and almost purchased a 10mm in case I ran into bear and needed some extra stopping power. I also considered the availability of 10mm ammo after talking it over on FR. Instead I brought my Ruger .357 and never saw a bear during the hike. In my head I debated the 10 rounds (Calif) and the 6 round capacity, and also brought 2 fully loaded speed loaders. I’m glad I never needed the gun and burned more calories carrying the extra weight.
Just get a .45 and quit worrying about it.
.357 is a smaller diameter bullet. Comparing energy at delivery, a full power 10mm round delivers more power. But since both will blow through most targets, it is a moot point anyway. (All that wasted energy existing the target, what a shame.)
BTW, I was not aware Glock manufactured 10mm ammo. Will it function in a Sig Sauer P220 pistol or Colt 1911 chambered for 10?
Both kill with extreme prejudice!
What about a Glock 357 vs. a 357 Magnum???
And does anyone know where someone can find the new Ruger PC9 that came out in December? The wholesalers I’ve checked with several times are out, out, OUT OF STOCK!
I had a friend in Alaska who’s father (A Vietnam and LE veteran) had just started reloading. He had a nice S&W M686 with a 4” barrel. He read a then-current reloading manual, saw the max load for the .357 with a 110 gr. JHP bullet, and poured in the max of WW-296 powder (very slow-burning and meant for longer barrels). We were shooting at my house in Wasilla. He stepped up to the firing line, assumed a proper shooting stance, and fired. What followed was one of the funniest scenes I’ve ever been witness to - a 3 foot diameter miniature sun exited the barrel after the bullet left and the concussion was so great it blew his baseball cap right off. He turned to me all wide eyed, opened the cylinder to safe the weapon, held it out to me, and said “Here.” After that I let him fire some of my more reasonable reloads and he realized it wasn’t the gun. I broke down his loads and as I recall there was something like 22 gr. of WW-296 which is way more than I would have contemplated putting in a 4” barreled handgun.
