Strongly considering a Rock Island in 10mm with threaded barrel to host my Octane 45 and probably a red dot.

What kind of power can be expected from a 10mm? What realistic distance would it be effective on pigs and deer? I love my 460XVR, but my god it’s too damn loud.

I can't speak to the distance part of your question, but I'd liken the power of the 10mm to a .357 Magnum, roughly. A handgun hunter (which I am not) could probably give you more specific info. But, when I'm hog hunting I prefer to carry my 1911 in 10mm before anything else as a sidearm because of the reasonable combination of mag capacity, power, and the advantages of carrying a semi-auto. I like 180-grain which I cast myself, but lots of guys prefer 200-grain bullets. I truly doubt there's a hog or deer out there that would know the difference. A big bear might, but I have yet to encounter a big bear in central Texas.

I had the single stack RIA 10mm— Vulcan cut it for an optic, no threaded barrel but I love that it’s an option now!!

Not a huge fan of that double stack mag.

With an SRO (2.5moa) and 180gr XTPs that pistol had no problem crushing headshots on the “hostage” TGT at 75y.

Killed one whitetail but it was only like 30y- no issues.

If they make a single stack w threaded barrel I’ll get another!

Had a buddy who had a big Smith and Wesson, bought it from a border patrol agent who was getting too many pass thru’s and hitting unintended targets.

I saw him shoot two pigs on the run with it when we came up on them in a feed pen, each boar was about 150 lbs and at around 30 yards knocked both on their bellies with nary a twitch….1 shot each.

It’s a serious round. I’ve thought about getting one in a Glock for carry in bear country

Buffalo bore lists thier 180 gr 10mm ammo at 1350fps. I load my 180 gr 357 to 1310 fps. I think you are spot on. It's very effective out to bow ranges. 40-50 yards max out of a pistol. With a longer barrel, it's good out to 100.

I can’t do single stack 1911’s, just uncomfortable to me. I have t handles a single stack or double stack 1911 in 10mm though, so I may change my mind. I have their double stack 9mm/22tcm and love the feel of it.

I have a single stack 10mm RIA and absolutely love it. It's on my hip anytime I'm walking through the woods and feel confident out to 50 yards.

Having had a couple 10mm, I would highly suggest either ear pro or a can. That thing will give you tinnitus like no other

If you aren't constrained by budget, Cosaint makes a 10mm double stack (2011) where you can customize it to your liking. I love mine in 45

A 180 gr 10mm at 1350fps is a stout load. Nothing a decent 10mm can't handle but if you plan to reload you might check to ascertain if the Rock Island has a fully supported chamber. And you might need to up the recoil spring or your brass is going to end up in the next county over.

Most 10MMs are factory set up for anemic loads but with a can and red dot maybe your slide speed wont be an issue with warm loads. I seem to recall that Chad also loads a warm 10MM load.

I have a RIA 10mm double stack and it's a nice gun. I have not shot an animal with it, but I do know some carry that round as bear protection in AK.

I have the long slide version of the single stack. Mounted a red dot on it and 50yds is no issue at all. Used it to finish off a wounded doe two years ago at about 40yds and I was amazed at the damage a 180gr XTP did. She had been jumped about 3 times before I got a shot, so her adrenaline was way up, but she went about 15yds max after the hit.

Wade,

The 10mm makes for a GREAT hunting sidearm. It's my favorite handgun caliber. The only reason I load 10mm ammo is for the lack of quality factory 10mm ammo. It's either watered down 40 cal S&W or a 10mm +P round. The +P stuff can have issues in cycling and reliability in the 10mm. Plus, they beat up the handgun a lot. During testing, my Glocks started having feeding and accuracy issues when you get up into the +P rounds. When you load the ammo to regular full power 10mm pressures (not +P), they work very well and shoot extremely well. I recommend the 180 grain and 200 grain XTP bullets. They do very well across the course. I've killed many hogs with both, and I prefer the 200 XTP for pigs. But 180 grain has also worked well on a charging pig, and would also make for a good self defense option. Shooting suppressed, I now load a subsonic 200 grain XTP round also. I'm about to make a run of the 200 grain subs.

Chad

I think Chad has a proper POV on this. A nuclear ++P 10mm load comes with too many compromises or the gun needs too many mods to be dependable. Roughly speaking the 10mm is loaded to 3 levels. Flat out wide open, 100 fps less than flat out wide open and 40 S&W levels. Hornady and Sig ammo (and others) fit well into that 100 fps from the top category and perform very well. They are my favorites (arthritis had something to say in that). Nothing wrong with the red hot stuff if it runs 100% all the time and in all conditions (assuming it's carried in the field). The problem is that it often doesn't.

I have the new Sig 320 X Ten, it's a beast. I would put it close to my 41 Mag. It came optic ready and have a Holosun 407c on it. Very accurate pistol and plan on using it on deer. I also changed out the trigger, not a fan of the flat triggers. Installed a Sig curved trigger. Much better shooter .

Hand loads is key with a 10mm there are not anything on the market that I would consider top end. I loaded many of these in 180-200 grains and my favorite was a hard cast with a nice stiff does of power pistol. Accurate enough for about 75 yards, could hit a paint pucket at 100 yard’s pretty easy with a dead hold. Think its on par with 357 mag, but everything has its limitations. In my opinion a 357 can be loaded far stiffer than a 10mm.

Love my 10mm. It is with me every step during hunting season.

I got some handloads from Chad for my 10mm. 200 if I recall. Very favorable. Found some factory that also shoots well for mine.

I'll be handloading after I'm done with all those. 180-200 seems like a winner from my tests.

I wouldn't hesitate to go for a pig at 50 yards, or a bit further out.

Glock 40, 6"

I wear a 2x or 3x glove and 1911s still feel odd to me unless I switch to thin grips and I do that to pretty much every one that I own eventually. Try out a set, you may like them. If you are local I can lend you a pair.

For hand loads I stick with 180 and 200 grain XTPs over a max load of what ever powder I am using. I have hunted white tails with those loads and will typically get a pass through or find the bullet under the off side hide. When I carry something in 10mm I normally use factory ammo and my go to load has been the Winchester Silver Tips for 20+ years because it is a near full power load and easy to find.

Everyone should own at least one 10mm. They’re very good in the 1911 platform. And even better in an Sig 220.

I load for 10mm and once you do you will appreciate the capabilities of the 10mm even more. 180 gr XTP is the bullet of choice, Nosler also makes a good 180gr bullet and the Speer 180gr Gold Dot is good too. You can get the Nosler 135 gr JHP bullets going 1550 fps within the load tables in a 6 in barrel for some serious water jug exploding fun.

Just a note on the +P loads, I had an accuracy and ES problem till I changed out the recoil spring and got even better results fitting a less ramped firing pin stop. I think the issue is not the recoil but that its unlocking too soon and giving erratic powder burn. And ejection was into the next county until I tuned it.
I have had the best results with Accurate #7 and BlueDot if you can find it. I tried W296/H110 with 180 gr loads and I think it was just too slow. Maybe with the 200 grain bullets it would work better.

They are really better in a S&W 610 revolver!

You spelled Ruger Super Redhawk wrong.

No doubt. You selling one? I’m tired of gunbroker prices. Only interests in no dash or -1. Not a fan of the Hillary Hole. Won’t own one.

Another vote for the 610 smith. Playing with a long slide Kimber now trying to finalize a load for it. Double stack RIA aint no slouch in the accuracy department either. Only problem with it is the 2 piece guide rod likes to come unscrewed. Yes im a 10mm junkie own 5 different ones.

Full power in a commander size Rock Island can be enlightening.

I think my TRP has that two piece guide rod. Not sure why Springfield did that. Dan “Kodiak” tri-color is a real shooter too.
