10mm Pistol Cartridge

[Harry Callihan]

I love 10mm. For defense I carry the Sig Sauer compact xten 320 with Underwood 155 grain XTP hollow points. I would not want to be on the receiving end of that.

 

[Mike SC Hunter]

A 10 is very similar in performance to a .41 Mag, That round was developed for law enforcement, so yea, a 10 should be great if you can handle the recoil and hit consistently with it.

If you check the specs on the 10 and the 41.......You'll find the 41 leaves the 10 in the dust....With bigger bullets too......BTw....I have some tens and like them....But none them come close to the 41.

Only a fool wants to be on the receiving end of any ammo..........

Only a fool points out the obvious as if it were enlightening.

Also, I dunno about you, but I'd feel a lot less worried about the prospect of being accosted by a thug packing .22 Short than I am about a thug carrying 9mm.

Thank you!

Even .22 Shorts will kill you..........

The 10mm auto is interesting cartridge for sure. At one point in my life I want to own a handgun in that caliber. Ammo is quite hard to find in Austria at good price so until I can afford that super expensive type of ammo I will hold the plans for purchasing a glock 20.

Back to the topic. You can find some reports about the 10mm auto in the latest Marshal and Sanow book as well.

It works and with some loads the one shot stop percentage rating is some high. You have to keep in mind though that the studies of marshal and sanow were quite controversial.

As far as I have heard at least. No expert in wound ballistics by any means so I cannot say if the bashing these studies or not is right or wrong.

I am sure we have some folks here that know much more about it then I do. I am just paraphrasing what I have read.

So please take everything I have said now with a large grain of salt.

For your entertainment pleasure;

This video is pretty decent summary of the 10mm cartridge and where it might fit best in the total scheme of handgun cartridge options.

I had a G29 but could not get comfortable with the short grip. Traded it for a G20…it's not my EDC but it's my mountain gun.

Not picking on you, but aren't the Glock 10mm's the one's that have "grenaded" on some shooters using the original hot loads, I've seen some pictures of that? Looking for confirmation or where those one-offs?

I believe the Gen. 2 Glock 22 & 23 .40 S&W models were the guns that exploded. I was next to a man at an indoor range that had a Glock 23 blow up on him. Unsupported chambers were the cause.

 

[Echo40]

I don't know about the Gen 5, but older Generations of Glock pistols chambered in 10mm Auto had unsupported chambers which could result in case failure when firing full-power 10mm loads, thus damaging the pistol in the process, ergo for the longest time it was recommended that anyone planning to shoot hot loads out of a 10mm Glock ought to purchase/install an aftermarket barrel with a fully supported chamber.

However, I know that Glock made some improvements to their Gen 5 Barrels, so this may no longer be necessary.

I wouldn't call the Gen 5 fully supported but my understanding is they did address some issues.

For me, it doesn't see a lot of use. At the range it's weaker factory ammo and the BB only goes in when I'm camping or hiking. I did shoot a few boxes through to test reliability and had no issues.

I believe the issues were blown out of proportion and mostly caused by over loaded hand loads.

The info about potential problems with 10mm glocks is quite intriguing. As mentioned in the post above I want to get a 10mm auto at some point in the future to own a semi-auto pistol with magnum-like ballistics.

But after hearing about potential problems with the glocks I might look into another 10mm pistol.

which 10mm auto pistols would you say are the most robust?

Something like a Colt Delta or the S&W 1076?

I have a Ruger SR 10MM and like it alot. It was ported somewhere in its life and that helps tame the recoil to about .45 ACP levels. A friend has two Colt Delta Elites 10 MM. His recoil much more than mine with the same loads.

From what I heard from FBI agents the " issues" with 10 mm was not the pistol or cartridge but those that fired the round. Basically many wimps…

I have heard it both ways. To much power and the pistols had numerous defects.

 

[HOUSTON RICK]

I have the ammo and a few S&W 10MM magazines, have not bought the gun yet.

 

[stansdds]

If I recall correctly, the biggest defect with the S&W pistols was the FBI's insistence upon it having no safety, but a Sig style decocking lever.

That is the reason I like it. Wished all my 3rd Gens had decockers on them.

Eww, hope he was okay?
Thank you, okay now I know.
Yeah, anyone that has a 10mm knows about the supported chamber feed ramps' importance.

The fellow was a large (about 6'4", 300#) black man. The exploding pistol cut his right hand in about four places and his left index finger. His right hand was swollen nearly twice its normal size in a few moments. He was real pale and starting to go into shock. The guy with me ran out and got a range employee and called 911. It was eye opening for sure.
