Ok, so it looks like I might be goaded into getting a 10mm.
So there are 4 models readily available and at opposite ends of price range, so let's hear opinions on these!!
Sig P220 Legion
Glock 29
Sw M&P
Rock Island 1911.

I got my P220 Hunter before the Legion was available in 10mm. Great gun and more accurate than I’m capable of.

Especially since mine is also a Gold Cup version. I have had several people try to buy it from me and the offers were high, but I still like to shoot it from time to time. If I ever get in a bind for money, I would probably sell it then. I don't see that happening though

At one time I did a complete survey of every commercial loading of 10mm, .357Mag, .40S&W and .41Mag on the web that listed velocity specs. That was awhile back--now it would take forever, but back then there weren't nearly as many ammo companies listing specs online. Anyway, that's how I came to the conclusion that there wasn't really enough difference between the 10mm and the .357Mag to make a hill of beans. Also that the .40S&W was a considerable step down from either the 10mm or the .357Mag.

And finally, that the .41 Mag, a few very light loads notwithstanding, was in a completely different class than any of them.Correct. And the only reason that it does is that there are a few very light .41Mag loadings out there. The .41Mag is a far more capable cartridge than the 10mm.

I absolutely love my .41magnum's. My only complaint is they are only available in revolvers. I have looked for the Desert Eagle in .41magnum, but have yet to find one. I would love to see someone build a 1911 platform that could handle the load, like Coonan Arms did with the .357magnum.

Pit my 4” S&W M58, hot-loaded, against a 4” M610, also hot-loaded with the same weight bullet (or one of substantially similar weight), and the .41 Mag wins ballistically by a wide margin.

Ream-out the M610’s cylinders to 10mm Magnum specs and it’s a different story. Not hugely, but the 10mm Mag wins.

IIRC, the old Coonan outfit did in fact try to produce a similar 1911-style model in .41 Mag to compete with the Deagle in that chambering. They may have made a few prototypes, but that was it.

The really interesting “mega-magnum” gun on the 1911-platform was the beefed-up old Grizzly models in .45 Win. Magnum. Supposedly, after AMT/IAI introduced their 8” AutoMag Mk IV pistol in 10mm Magnum, the Grizzly folks responded with a 10mm Mag “conversion kit” for their guns.

This was all back in the day, so I’m going largely from memory. But I believe this conversion kit consisted of a 7”+ 10mm Mag barrel, a magazine, and maybe springs. Again, just going from what I can recall this far down the road. Some THR member here might actually have one.

But the Grizzlys were definitely a higher quality gun than IAI’s line of AutoMag Mk IVs.

I shot my brothers old Delta Elite and it’s a nice shooter. But I don’t see why the original basic DE are selling for $2400+, I can only guess what the Gold Cup version would fetch

Then it wouldn't be a 10mm any more would it?
 
10mm is nice for sure and provides plenty of ft/lbs of energy. It is definitely in magnum equivalent territory but that would be .357 magnum territory and maybe entry level .41 magnum territory, not .44 magnum territory. That kind of muzzle energy is relatively easily available however via the 460 Rowland. My 460 Rowland drives a 230 grain XTP at around 1,250 fps out of a Glock 21 with 11.7 grains of Longshot. That's 798 ft/lbs with a 5" Lonewolf threaded conversion barrel.
By comparison, ballistics by the inch records getting a Federal 240 gr. Hydra-Shok JHP up to 1,227 fps out of a S&W 629-5 .44 magnum with a 4.875" barrel. That's 802 ft/lbs with a 4.875" barrel. The .460 Rowland is undeniably in 44 magnum equivalent territory. What's more, my 11.7 grains of long shot is .3 grains below the max listed charge of 12 gr. so I can speed things up a little more if I want to but I choose to stay below max. Hodgdon lists 1,336 fps with a 230 gr XTP and 12 gr of Longshot out of a 5" barrel. That's 911 ft/lbs of muzzle energy, undeniable .44 magnum equivalency in an autoloading pistol using a cartridge case that is only 1/16" longer than a .45 acp. Also, in the Glock 21, you get 11 rounds of this cartridge per magazine, easy magazine changes and the ability to make fairly rapid follow up shots. Shooting this cartridge out of a Glock 21 is fairly enjoyable btw. It feels a little bit like Mjölnir I imagine. very gratifying.
If you want a magnum autoloader, the 460 Rowland will fill that niche. Mind you, I own two 10mms and I carry a 9mm. But I'm just sayin'.
It just seems worth mentioning since we're comparing 10mm to magnum revolvers and discussing ways to shoot magnum revolver cartridges out of autoloaders (coonans, Deagles, grizzly mags, etc).

I say get all 4!

.357 - 10mm - .41 -.44mag

I've got all four. The .357s don't see daylight anymore. And the .41 rarely emerges from the safe to get hung from a belt.

If the 10mm doesn't seem like enough, I go straight to a .44 Mag with 300gr hardcast at 1200fps. These days, if I'm carrying a wheel gun, it needs to be well worth the extra bulk and reduced capacity.

I want to carry a .44 with hard cast or solid for my hike in the woods. You know about the Big Foot like animal that has been stalking me? happened 3 times. I been carrying a 5 shot .460 with full house loads but it’s getting kidda heavy

Actually it still would be. o_O

The 610s are fed by 6-rd moon clips. So even after the magnum "conversion" of the cylinder chambers, the .40S&W, 10mm AUTO, and 10mm Magnum cartridges can still be loaded and fired off these clips. The backend of the three cartridges are the same dimensionally.

The conversion turns the 610 into a 3-in-1 gun, and more than a few 610 owners have had a wheelgun-'smith do it to their gun.

If I recall correctly, master gunsmith Hamilton Bowen pioneered the conversion, but any 'smith who's competent to work on revolvers and has the reamer should be able to do it.

.41 mag in an autoloader would be cool.

I'll probably skip the .41 for now. 10mm is happening as soon as I make up my mind which one. .44mag is next after that. 10mm mag does sound interesting. Having shot a .454 and a 500sw, I'm not looking to keep jacking up the cubic inches, just looking for one that can be reasonably carried and stop a bear or ten if needed.:cool:
