.460 Rowland vs 10mm: Which One for Bear Country?

.460 Rowland vs 10mm: Which One Actually Belongs on Your Chest?

If you've gone looking for a semi-auto to carry in bear country, you've run into both of these. The 10mm is the default answer. The .460 Rowland is the one people bring up to tell you the 10mm isn't enough.

Both work. I build chest holsters for both, and I've had this conversation with enough customers to know that the ballistics chart is the least useful part of the decision. Let's get it out of the way first, then talk about what actually matters.

The numbers

Both loads below are Buffalo Bore hardcast — same maker, same bullet type, and both figures are their real-world numbers out of actual pistols rather than laboratory test barrels.

A heavier bullet, a hundred feet per second faster, and about 36% more energy. On paper the .460 Rowland wins and it isn't close. It's a .45 ACP case lengthened a sixteenth of an inch so it won't chamber in a .45, with a stronger web, loaded to roughly double the pressure. Buffalo Bore put it plainly — as they load it, it sits "squarely at mid .44 Magnum power levels."

Buffalo Bore isn't your only option on the 10mm side either. DoubleTap's 200gr hardcast is a good load — lighter bullet, moving quicker, and plenty of people run it for exactly this. Both companies make ammunition worth carrying, and either will do what you need it to.

So that's settled. Except it isn't, because almost nothing about carrying a gun in the backcountry is decided at the muzzle.

First, let's kill the capacity argument

You'll read that the 10mm gives you fifteen rounds against eight. That comparison is dishonest, because it isn't comparing cartridges — it's comparing a Glock to a 1911.

You can run either cartridge on either platform. Compare them properly:

Two rounds on a Glock. One on a 1911. Capacity is a platform decision, not a cartridge decision, and anyone using it to argue you into a 10mm is arguing you into a Glock without saying so.

So pick your platform on how it fits your hand and how you shoot it. Then pick your cartridge on what follows.

What the chart doesn't tell you

You can buy 10mm anywhere. Walk into any shop in Alaska and there's 10mm on the shelf. .460 Rowland is a specialty order — Buffalo Bore, Underwood, or you handload. That's fine if you plan ahead. It's less fine three days into a trip when your ammunition went down a river.

The .460 Rowland needs a compensator, and it isn't optional. This is the part people gloss over. The conversion runs at pressures a standard .45 ACP slide isn't built for, and the comp is what keeps slide velocity survivable. It's not a muzzle accessory you bolt on for looks — it's structural to the design. Which means you're carrying a gun that's longer than the stock version of whatever you built it on, with a device on the end of it, and it's louder than you'd like without ear protection.

It also adds roughly two inches of length. A 5" 1911 with a comp fitted comes out around seven inches of pistol; a Glock 20 lands near six and a half. Whatever you end up carrying it in is going to be bigger than the standard version. Not a problem, just something to know before you order.

Credit where it's due on the comp, though: Buffalo Bore loads the .460 Rowland with flash-suppressed powder specifically because they expect these shots to happen in low light — on the reasoning that you don't want to be blinded by your own muzzle flash at the exact moment you need to see. That's a thoughtful piece of design for a woods gun and it takes some of the sting out of the argument.

The .45 ACP thing, which nobody makes enough of

Here's the .460 Rowland's genuinely underrated advantage: the same gun shoots .45 ACP.

That matters more than it sounds like it should. The gun you carry for bear is a gun you need to be genuinely good with, and being genuinely good with something means putting real rounds through it. Full-power .460 Rowland is expensive and punishing. .45 ACP is cheap and pleasant. You can do the volume in .45 and the confirmation work in Rowland.

Try that with a 10mm and you're either shooting 10mm or you're shooting a different gun.

The part I actually get asked about: carrying the thing

This is where I come in, and it's the part that tends not to come up until after the gun is already bought.

A .460 Rowland conversion doesn't fit a standard holster — and it doesn't matter what you built it on. 1911, Glock, FN, it's the same problem. The compensator sits on the end of the barrel and there's no factory gun that length to mold to, so it's a build-up job rather than something anyone has sitting on a shelf.

I build it two ways. An open-bottom rig, where the comp protrudes out the end — and I'll say plainly that I don't like open-bottom holsters as a general rule, but this is the case where it makes sense, because you're not carrying a standard gun and there's nothing standard to build to. Or a custom molded to enclose the comp, if you'd rather it covered.

I've built a few of these now and I'll be honest: there's nothing difficult about it. They all worked out fine. The only real decision is that one — exposed or covered.

And for what it's worth, almost everyone wants it showing. People who've gone to the trouble of putting a comp on a gun tend to want to see the thing. I don't blame them.

So which one?

Strip out the platform argument and it comes down to two honest questions about how you operate.

How do you buy ammunition? If you order a case in spring and you're set for the season, the Rowland's specialty supply is a non-issue and the extra two hundred and fifty foot-pounds is yours. If you tend to pick ammunition up the week before you leave, the 10mm's availability is worth a lot.

How do you feel about the comp? It's louder, it's about two inches, and the holster becomes something built rather than bought. For some people none of that registers. For others it's the whole decision. Neither reaction is wrong.

Answer those two honestly and the choice generally makes itself. Hardcast out of a 10mm has stopped bears, and it's what a lot of people who spend their working lives in that country have settled on. The .460 Rowland gives up nothing on power and beats it outright, and if the supply and the length suit how you operate, it's a genuinely excellent woods cartridge that doesn't get the credit it deserves.

And the honest answer to the whole argument is: yes. Buy one. Or the other. Or both. They're both good cartridges, they'll both do the job, and I've built rigs for people running each. The debate is more entertaining than it is consequential — what matters far more is that you shoot whichever one you pick, and that you can actually reach it when you need it.

Which of the two I'd pick, since you asked

Everything above is me laying out the trade-offs as straight as I can, because both of these are good cartridges and I build for both. This next part is just my own preference, and you should weigh it accordingly.

First, the honest answer: I'm a revolver man. Given a free choice I'd have a wheelgun on me, and that goes for bear country as much as anywhere else. It's what I've carried for years and it's most of what leaves my shop.

But that isn't the question on the table. Asked to choose between these two, I'd take the Glock 20 in 10mm — and for one reason only: ease. It's a factory gun running factory ammunition. Nothing to convert, nothing to fit, nothing to order specially, and fifteen rounds of hardcast Buffalo Bore will do the job.

That's a preference, not a verdict. If you're running a Rowland you've made a perfectly good decision and I'll happily build for it.

There's also something worth saying that doesn't get said often enough by people who sell holsters: if I'm out there, I've almost certainly got a rifle with me, and the rifle is always more capable than the pistol. The handgun is what's on you when the rifle is slung, propped against a tree, or on the other side of camp. That's its job. It's not the primary, and choosing between two good cartridges for it matters a lot less than people arguing about it online would have you believe.

Carrying either one

Two different jobs here, and they want two different holsters.

Under a pack, miles in, bear country — that's a chest rig. A pack belt buries a hip holster, and a bear is not a situation where you want to be digging under a hip belt to find your gun. This is what the Kodiak exists for.

Everything else — the range, the truck, working your own property — that's a hip holster, and there's nothing second-best about it. A gun like this doesn't only come out on hunting trips. When there's no pack belt in the way, the Urbanist rides close and clean, and the Urbanist Crossdraw is the one to look at if you spend real time behind a wheel or in a saddle.

I build both for comped conversions, same as I do for anything else.

If you're running a Rowland, message me before you order. There's only one decision to make: comp protruding out an open end, or fully enclosed. Tell me which you'd rather and I'll build to it.
