A 10mm revolver can shoot 40S&W in a similar fashion to 38 Special in a 357 Magnum. The 10mm revolver always comes factory ready for moonclips and we all know moonclips rule. :neener: If you have your 10mm Auto revolver reamed to 10mm Magnum you now have a three cartridge revolver with no hardware changes. Mix and match on a single moonclip if so inclined

Many of the 10mm Auto semi-autos can be converted to 40S&W or 357 Sig with a barrel change. Its also not unheard of to shoot 40S&W from an un modified 10mm Auto especially with Glocks but I suspect most of the 10mm M&P and XD could handle it too.
My XDm shoots .40 fine
 
Like many members I don't have a 10mm but would like to get one! In some areas like capacity the 10mm had an advantage over the 357. The larger diameter is also a plus.
I'm glad that it is making a come back and that gun manufacturers are making new models chambered for the 10.

I have a lot of factory .40 S&W, and even the premium stuff shoots soft from the XDm 10MM I have. My Glock 20 used to shoot it fine too. I've not shot thousands of rounds, but several hundred through the XDm and totally reliable. Plus, I have several thousand cleaned and deprimed cases ready to load!

Hypothetically speaking for this one center fire cartridge scenario I would probably be happier with 40 S&W chambered guns one small like my Walther PPS and the other a STI 2011 with that you could load the 40 over SAAMI length and mimic 10mm loads at least with the heavier bullets.
 
I'll play!
* 10 mm Auto, because I prefer the cartridge
My two favorite 10mm (at this time), SIG XTEN and S&W M610. I prefer the M610 by a hair.

Are you using AA#9 for this load, mcb?
am pushing 200gr XTP from my 610 at 1250 fps and I am not using the max charge I have seen for the powder I am using...

As I said, currently my only 10mm gun is an S&W 610.

if I would to add a 10mm semi-auto, I’d get someting based on a 1911 pattern gun.

I like shooting a 1911, I have lots of experience shootng 1911 pistols, I have lots of experience workng on 1911 guns and I have 40’S&W and 357Sig chambered 1911 guns.

I enjoy seeing what others are doing with a cartridge/gun combination.

Though I said I prefer .357 and revolvers I seriously considered a Glock 20 for protection when hunting in Oregon. Having a sidearm loaded with 15 rounds vs 6 or 8 of a comparable cartridge would be a comfort should things get hairy quick.

Even though I am pretty sure shooting 10mm from a Glock will bother my wrists due to slide movement I cannot get the G40 out of my head. I actually wasn’t aware of the G40 until a short while ago. I may try to rent one, or a G20, just to make sure I can or cannot shoot one comfortably…once my local range gets some 10mm ammo.
 
I prefer the 10MM for the bigger diameter hole given I'd use either of them for a woods gun mainly. I carried a G29 for a few years on and off and it was totally doable for the streets, but I think the .357Magnum/revolver shines for the street vs woods considering the profile of most 10MM guns are thicc.


I voted 10MM because it's what I have and love. The .357 is a good choice, I just prefer capacity.
 
Seems like the 41 magnum and the 10mm would be a closer comparison than the 357 magnum vs the 10mm?
Nah, 41 Mag is a much more powerful cartridge, and there are even LESS options in guns than 10 mm.

Many of the 10mm Auto semi-autos can be converted to 40S&W or 357 Sig with a barrel change. Its also not unheard of to shoot 40S&W from an un modified 10mm Auto especially with Glocks but I suspect most of the 10mm M&P and XD could handle it too.
How would this be done? In an auto, they headspace on the case mouth, so the 40 S&W would sink into the chamber and if it did work, it would be loose in the chamber. Doesn't seem feasible or smart.

.41 Magnum easily wins over 10mm, and of course .357 Magnum, but .357M is also a bit better than 10mm, although they are close. It comes down to sectional density of the bullets, which translate to better penetration when bullet weight and velocity are similar.
Well, that's if penetration is a concern. Unless hunting big game at longer distances, I wouldn't think it would ever be a concern with either of these two cartridges.

My XDm shoots .40 fine
Again, how? Doesn't the cartridge sink down into the chamber too far?

Well .. I picked the 10mm
Only ONE centerfire handgun cartridge…
So no 38spl if I chose the 357
Well, you got me on the wording. I would allow 38 Spl from a 357 or 40 S&W from a 10 mm w/ barrel swap. (in an automatic).

Even if it weren't "allowed" 38 Spl-level reloads out of a 357 Mag case is a beautiful thing. I do that all the time to avoid the carbon ring issue.[/quote]

Most modern semi-auto handguns are controlled round feed, ie as the case head slides up the breach face the rim slides under the extractor as it rises up out of the magazine. So as long as this works reliably the shorter 40S&W round then headspaces on the extractor rather than the case mouth. This has proven to be remarkable reliable for most that have tried it.

I don't know 10mm. All of my pistols are 45 ACP or 9mm, which are the most common. Not sure why you would compare the most popular revolver cartridge with a less than popular pistol cartridge, but there you have it. ;)
 
For your “Only centerfire handgun rule” I’d have to go 10mm for its ability to be had in an auto.

If you compare Kinetic Energies from Buffalo Bore (I like to use them as a real world hot handload comparison.) .357 mag technically has more. But that is only comparing KEs.

I enjoy my .357 Security Six as a woods gun, target gun, and think there are some serious benefits to conceal carrying a revolver. They are as idiot proof as a gun can get. If something goes wrong just pull the trigger again. So for a woods bear gun I’d rather have a .357 Revolver. But after reading several accounts of bear encounters the pistol cartridge you have is likely not going to make a hill of beans of difference. The knockdown or shock value of a gun on a bear will likely only be seen in a high velocity rifle. For pistols, you’d better hit something important.

So I only get one centerfire handgun? It’d probably be one of the new 10mm Autos. Its not likely I will ever see an angry bear or a gunfight. But a gunfight is probably a gnat’s @$$ more likely to happen and for that I want the more modern firearm. I just deal with more people than I do bears .

Thanks. I had no idea how it works, just that it does, and in my case, pretty much flawlessly.

I will say as a general rule, the .40 SW isn’t as accurate as 10 MM rounds but that could be because I’m still shooting up a pile of 12 year old Freedom Munitions cheap and dirty reman ammo.

It worked for my stock G29 and a Lone wolf barrel I tried. It's not "ideal" but I a situation where it's required it can reliably suffice.

The HiPoint 10MM carbine w/bullpup conversion would make a great carbine.
I do lend myself favoring the .357 for it's ubiquitous availability in carbines. The HiPoint and a few elusive AR uppers exist in 10mm for carbines options. Maybe the MechTech upper if it comes in 10MM?

I bring up carbines because in my limited experience the .357 carbine I shot fed .38 fine. I have no experience shooting .40S&W in a carbine chambered for 10MM.

Also, .40 caliber got it's first debut in the .38-44 correct?

Buddy of mine has the G29 he likes to carry when bow hunting. Now that’s a snazzy package. I looked closely at the new Springfield (XDM?) in 10mm. Serious anti-personnel package.
 
As a disclaimer I have never owned a 10mm. I am currently working at saving up to get into hand loading. I am however trying to find another 686 I used to have one that was a department trade in. Like a fool I sold it to a friend to fund the purchase of a 45. I would choose the 357 because of the ability to use 38 specials and to load various weights of bullet. Plus you can find a lever carbine in 357 easier than 10mm carbines.

Until the Glock there really wasn’t a handgun that could handle the 10mm. I know there was the colt trophy cup but it also beat itself to death overtime. 10mm seems to be a love it or hate it caliber. I just don’t see it as practical for my needs.

And you can get a Small lightweight revolver in
40 S&W

As of this time, 66 for .357 but only 41 for 10mm.
I prefer the revolver as it is much less likely to jam than any auto-pistol. I believe that the .357 has more bullets of different weights available to it than the 10mm, although the 10mm may be able to use heavier bullets than a .357.
