A 40 actually gets more chamber support in a ten...

[@richstone2627]

Most 10mm ammo sold is loaded to .40 S&W specs.

[@Pyle81]

But not ALL, Especially NOT the Self Defense or Hunting Loads. And its more of a concern of the head spacing. Its not going to effect the shorter 40 cal. Its going to effect the longer 10mm. We (in the Gun Smithing World) have seen 10mm severely damaged and destroyed do to just this issue. We aren't talking about 9mm target rounds. We're talking about HIGH PRESSURE +P+Rounds going off unsupported or in worse case even out of battery. This isn't like accidentally running a 380 ACP round or a 9mm Makarov into a 9mm luger. As it was explained to me by Dennis at S&W in Ballistics, Its like putting a 5.56 round in 9mm and pulling the trigger. "Its all bad when it goes bad"

[@mrgunner5351]

The 10mm was NOT developed for the FBI. It was a developed at the urging of Jeff Cooper by Norma as the ultimate “replacement “ for the 45ACP. Dornas and Dixon made the first pistol for it, the Bren 10, which was a beefed up CZ75. This all happened well before the Miami shootout which is the incident that drove the FBI to look for a more powerful round for agents to carry. The 40S&W on the other hand…

[@leadisgood]

Also , before there was the 40 sw , there was a downloaded 10 millimeter called the fbi load.

[@11C1P]

Most current factory production 10mm is loaded to the same velocity most factory 40cal is loaded to.

[@CountryTortoise]

I keep seeing people say that but the majority of 10mm ammo I see is loaded to 9mm velocity which is about 100fps more than most typical 40 s&w ammo

You can already shoot 40 out of a 10mm Glock without issues but if your going to do it on the regular having a barrel designed for it makes sense .

[@TheAxe4Ever]

What do you mean by “designed for it“? A 10 mm can obviously handle the pressure in the chamber. There’s not enough of a difference in the length between the 40 Cal and the 10 mm to make a difference. The thickness of the projectile is the exact same. The twist rate of the barrel is the same even though that wouldn’t make a difference between the different rounds. This is just a way for him to sell product. But that’s OK. Yay for capitalism!

I bought a 10mm barrel for my G21 (.45acp) and found that it also shoots .40 S&W just fine. Of course the .40 headspaces on the extractor, so it may not be the best long term solution. If I was going to shoot a lot of .40 S&W through it - which I'm not - I'd probably buy the .40 barrel, but for occasional use I think it's fine.

"NOTE" Actually right now 10mm ammo prices on some brands has come down a lot. And I have seen a lot of 10mm cheaper than than 40 S&W many times lately. Since 40 S&W has become the "Not for the Cool Kids caliber" and kicked aside. So 40 S&W is not being as massed produced as it was it now costs more.

​@@arlissyoung8899Wrong...... I love you guys think its all about a dollar. Because you clearly don't know 💩💩💩💩💩💩💩 about guns. Because if you did, You would understand how straight wall pistol cartridges HEAD SPACE off the mouth of the cartridge. And what happens when you get BUILD UP or DAMAGE to this area in the chamber. The 40 round isn't going to be the problem. However the 10mm WILL BE. Don't believe me??? Call the company that made the 40cal. Smith&Wesson. Ask for Dennis in Ballistics, He'll be happy to explain it to you. And show you chamber dimensions and pics of what happens when it goes bad.

[@Pyle81]

Hey my friend, Very good question. And here's where you will find the answer. It's called "Head Spacing" straight wall pistol rounds like the 40 cal. and 10mm (And others) head space off the mouth of the case. You can call S&W who came out with the 40cal. And talk to Dennis there in Ballistics (or anyone elese) They will explain it to you in depth on why you DO NOT WANT TO DO THIS. If it was me and in a life or death situation, Thats one thing. But ONLY in that situation. Its not like shooting 38's in a 357 as others that are less informed think its fine to do. PLEASE DO THE RESEARCH AND IF YOU STILL AREN'T SURE. CALL THE PPL PROFESSIONAL THAT MADE THE ROUND, Smith & Wesson. They'll be more than happy to speak with you about this issue.

Man, I don't know where the economy is with 10mm vs 40 cal? Miniscule difference. By the time you pay for another barrel and then you're practicing with a round that isn't the same as your main carry? What's the economy or efficiency with that? I don't get it? I don't like it but , for me anyway, I just suck it up and pay the price for 10mm. Then, I know I'm ready for whatever life throws at me. 10mm, even full powerhouse loads no big deal. After shooting/carrying 44 mag most of my life 10mm is like a breath of fresh air. Plus 3+ times the firepower. I'm glad 10mm is gaining popularity. Maybe prices for ammo will get better soon?

Can you use this 40cal conversion barrel in a Glock 21?

[@ClickClack_Bam]

You can always go down in caliber from a higher caliber Glock, but NOT the other way around. So a 45 cal Glock can run conversion barrels from 40, 357, 9mm etc. So in essence buying the highest caliber Glock that you'll ever want to shoot has the MOST value because for not much more money you can convert them to whatever other caliber you'd like WITHOUT buying the extra firearms. Go look at other after market Glock conversion barrel makers as well. I bought a 40cal to 9mm conversion barrel from Aim Surplus for $50 & the same exact barrel but with blemishes for $30. I can't even see where the supposed blemishes are but they work fine. So for well under $100 I bought a barrel & a 9mm magazine & have myself a 9mm Glock now & it's essentially an unregistered ghost gun.

Is there anyway I can convert my Glock 17 to a G 31?

[@mrgunner5351]

No. The slide is made for a 9mm dimension barrel. Mainly, the hole in the front of the slide. You need a 40S&W dimension slide and barrel. The 357Sig is based on a case of similar size to the 40, only necked down to 9mm. I guess you could get a different slide for your frame.

[@everettware3466]

K, can I still shoot the 10mm ammo with the conversion barrel or do I change it out every time I shoot 10mm ammo.

[@rudyschwab7709]

You would have to change it back for 10mm. The .40 S&W chamber in the conversion barrel isn't deep enough to allow the 10mm to fully seat in it. The primer end of the 10mm cartridge will stick out of the chamber and the slide will not be able to close all the way.
