10mm coming back in style?

[anothernewb]

Might be off track - but I wonder if 10mm got a boost from the last shortage. I remember seeing lots of 40 and 10 on the shelves, but no 9 or 45. 40 eventually went - but in my area 10 never really got touched. Perhaps for them it was a good time to buy a firearm - for what ammo you can get.

what agency issued 10mm mp5s?

FBI starting in the 90s, not sure how long it lasted, I know the 10mm pistol was short lived with them. Not sure how long they kept or if they still use the MP5/10 in a limited role or if its phased out or what.

The MP-5/10 with semi auto and 2 shot burst capability was a general issue long gun for standard agents in the 90’s and early 00’s. By bureau policy the select fire version could only be issued to SWAT, HRT, and firearms instructors. The ammo used was Federal 190 grain JHP, and 180 grain FMJ practice ammo.

The bureau switched to various M-4 style long arms after the MP-5/10 was no longer supported by HK and repair parts dried up. It soon became a SWAT only arm and its numbers dwindled rapidly. There were still some examples in the field when I retired a couple of years ago.

It was a very capable firearm.

I think the 10mm is more popular than ever.
With good reason .
It does everything the standard service cartridges do only better. More power & flatter trahectory for a gun the same size as a 45. To me it's a no brainer, I had a g21 for years , when I got a g20 I had no use for the g21 anymore. That was a tough one for a minute because I've always preferred a 45 acp for general pistol use. The benefits were undeniable and I could shoot it just as well .
Being a powerful cartridge the nay sayers can only say "it's too much recoil" or "if I need more than a 9mm , I'll use a rifle", which is just goofy. If you want less recoil get some 40sw power level rounds- that's easy to find or load up some truly powerful rounds if the need arises- a 9mm can't even come close.
My primary use for the 10mm is as an edc gun that combines power, capacity & reliability . it just does so many things well and better than whatever other auto loading pistol cartridge you'd like to compare it to.
I don't consider the 10mm a big bore , some guys do. It's still relatively weak and little but has a lot to offer. It's plenty for most things .
If I'm in hairy toothy critter territory I'd still take a big revolver any day but I live in illinois, the biggest, hairiest and meanest thing around here is my neighbor , Bob .

If You already Hand load for 40 S&W then you already Have almost all you need to work with 10MM. Cases and Large pistol primers and you are there at basically the same cost!!!

 

[orionengnr]

For me, .45 acp has always been my go-to semi-auto round. I've owned a number of 9s through the years, and still have a couple.
I jumped off the .40 ship more than ten years ago, and into 10mm about the same time.
Only have the one (DW CBOB), but I load for it, shoot it and enjoy it.
Doesn't replace the .45acp, but is a nice complement to it.

 

[cfullgraf]

I could not pass up an S&W 610 last year so that was my first "toe in the water" with a 10mm. So far so good. I do like revolvers with moon clips.

Hopefully supplies can get back to reasonable levels so I can start reloading 10mm.

Maybe a 1911 style 10mm is in my future.

 

[sparkyv]

Almost...then again, my M610 is rated for 10mm Mag pressures, which gives me more 10mm Auto handloading options, well beyond 40S&W.

I have had a Delta Elite for many years and picked up a Ruger 10mm 1911 shortly after they came out. Shooting them side by side the Ruger seems easier to shoot and is more accurate by far. A difference in recoil springs and the Ruger having a heavy barrel might be some of the reasons it 'seems' easier to shoot but I'm no engineer, I carry it in a chest rig when I ride the 4 wheeler or walk in the woods. Bear and Mountain Lions have been sited in the woods behind my house as well as wild Hogs.
I would really love a gas operated (direct impingement) 16 inch 10mm AR. There is at least one guy that's makes them that I know of, got to save the coin first.

Is the Ruger 10mm 1911 a fully supported chamber set up?

I have the MeckTeck rifle conversion for my Glock 40 MOS shoots Great. Is Heavy. Really want to use it for a deer or Hog. Lotta fun to shoot. Very light Recoil.

The 10mm Ruger is a fully supported chamber.

The 10mm Ruger is a fully supported chamber.

Steve........

You decide:

 

[Steve E]

I will say my Ruger 10 mm has a 'supported chamber', (fully supported ?) with an integral ramp while my Delta Elite has a 'regular 1911 style' chamber. I believe the Ruger 10mm 1911 uses a Wilson/Nowlin ramp style barrel but I could be wrong.

[anothernewb]

Huh, you'd think I would have checked mine, but I've fired many hundreds of some heavier loads of 10mm through my ruger. never seen a bulged case yet. It's primary diet is 180 grains pushed by 10.5 of blue dot. Never seen an issue.

 

[Steve E]

I usually run 180 gr cast or jacketed bullets, most loads are with Accurate #9 or Power Pistol running between 1100 and 1200 fps, I haven't had any problems with brass in the Ruger. I had some really hot loads in the DE that did show some bulges (but not in the Ruger 10mm) so that was marked as too hot in the DE in my notes. I did pick up some CFE Pistol recently after using it (CFE223) in my 6.5 Grendels with super results so hopefully it will give great results in the 10mm. Great powder Blue Dot, I looked for some but no one around here stocks it even before the China Flu took hold.

I wish S&W would make the M&P in 10mm

Bear country?

For EDC in most places, the extra power would be overkill.

it just does so many things well and better than whatever other auto loading pistol cartridge you'd like to compare it to.

Except for rapid controlled fire.

These are the reasons why the 10mm fell out of favor for law enforcement and SD in the first place.

 

[bigmike45]

I’ve loved the 10mm for over a decade. It’s the closest semi auto round I could find to my favorite .41mag revolvers. I have three:
Stainless Colt Delta Elite Gold Cup (Don’t shoot it much due to value and unsupported chamber)
Stainless Smith and Wesson 1066
Springfield Armory XDM 4.5

I love handloading for this caliber!!

Depends on the ammo you select, having the option of power similar to 40 SW gives controllable characteristics and is not overkill for urban environments. If more power is desired it can do that too. Having the option is nice and with the larger guns associated with 10mm, 40sw type loads can be fired quicker and easier than a gun chambered for 40sw. Win/win. Just my opinion and worth what ya paid for it.

 

[upptick]

I see it all the time, the comparisons of 10mm to 41/44 Mags, its not even close when you compare apples to apples (i.e. full house loads). I love the 10mm but I've got to have a foot down on reality. It's a 357Mag performance in a semi-auto platform, which is why I don't really understand 10mm in a revolver, but there are those that really enjoy them as well. I have full confidence in my Glock 40 for my needs of woods protection. Now if I'm hunting in Alaska which may never happen but who knows, my Ruger Alaskan in 454 Casull gets the nod.

The underlined and bold statement is the 10mm "claim to fame" and where it's worth should be understood. I can cherry pick loads to make 9mm equal 357magnum, or 40 S&W equal 10mm, direct comparisons matter if one wants to find the truth of the matter.

If 10mm is like a .357 magnum, how does it compare to a .357 Sig?

This is precisely why I recently picked up both a .40 and a 10mm -- ammunition for everything else has been sold out for months, but where I am .40 and 10mm is still available.

 

[upptick]

I recently picked up a Glock 20. As I've been learning about the 10mm, I've discovered it's a great candidate for a carbine. With a 16" barrel, some loads exceed 2000fps.

 

[Havok7416]

If 10mm is like a .357 magnum, how does it compare to a .357 Sig?

.357 Sig is designed to mimic 125-grain .357 loadings. 10mm was originally built around 180-grain loads (and can go up to 220gr). Just my opinion, but I'd say 10mm comes out ahead of .357 Sig in terms of performance at the high end.

 

[loadedround]

Never knew that the 10 mm cartridge ever went out of style!
