Money isn't the issue;in my neck of the woods 10mm is about the same price as .45 ACP. The trouble I'm having with this round is consistent supply. I've been able to find reasonably priced rounds here and there, but its been ad-hoc ordered across different online sellers.
Given California's forthcoming restrictions on online and over the counter purchases of ammo, in your shoes i'd invest in reloading equipment with a quickness.The more prohibitions you have, the less virtuous people will be.

On the advice of 40S&W, if you are shooting a Glock, you can shoot 40 out of your G20/G29 without a conversion barrel.
I even load 10mm loads (mainly heavier bullets) using 40S&W cases. These rounds will headspace on the extractor, so they work fine. Just make sure you spend some time with a chamber brush and a good solvent before trying to use the gun with standard 10mm ammo, as you will get some fouling at the end of the chamber with the shorter brass.
If you get a conversion barrel, then you eliminate the chamber cleaning step.When asked what qualities he most valued in his generals, Napoleon said, "give me lucky ones."Comment

This is not accurate!
Note how deeply set into the S&W Model 1076's chamber the .40 S&W round is in the photo to the left. If the pistol were fully assembled, the cartridge's rim would not be engaged by the extractor claw. Or, if it was, then the round would be headspacing off the extractor, with only the tension of that part to hold it firmly against the breechface. And that's where the trouble starts!
Why shooting .40 S&W out of a 10mm is a bad idea.The more prohibitions you have, the less virtuous people will be.
The more subsidies you have, the less self reliant people will be.

OK, then don't do it.
Notice I didn't say shoot your 40S&W out of any 10mm handgun, I said if you are shooting a Glock, you can shoot them and they will work fine.
I shoot both 40S&W and 10mm load using 40S&W cases out of my G20's an G29's all the time, many, many thousands of them. They work fine for me, never a single glitch.
I suspect you either don't have a Glock 20/29 or never tried it, either way you don't have the slightest clue what you are talking about.When asked what qualities he most valued in his generals, Napoleon said, "give me lucky ones."Comment

Look, it has nothing to do with being immune to the laws of physics. The Glock's firing pin isn't going to reach the primer if something incredibly rare happened and the round jumped the extractor and headspaced on the case mouth.
Here is the deal, anyone who has the slightest bit of fear, uncertainty or doubt about the practical use of 40S&W in a 10mm Glock should heed your advice and not do it, period.
That doesn't change the fact that you have not the slightest idea what you are talking about, clearly have never tried it, which is fine, it is what the internet is all about...When asked what qualities he most valued in his generals, Napoleon said, "give me lucky ones."Comment

I read the article (great article by the way, thanks for the link), worst case scenerios seemed to be peirced primers (probably because the cartridge chambered all the way forward until the case mouth stopped it). He also mentioned possible feeding and cycling problems. Keep in mind this is out of a smith.
I would never advise anyone to shoot .40 out of a 10mm, but theres several other members here that do it all the time. In fact they dont report pierced primers or cycling problems (leading me to believe the glocks extractor just latches on better). The ones with glocks anyway.
I have a G20, and i would do it if for some reason i felt the need to shoot .40 instead of 10mm. Cant imagine what that situation would be since i can load both for the exact same price. Im not seeing any safety reasons why it shouldnt be done.
Again, i would never suggest for anyone to do it.Last edited by Dark Mod; 06-14-2013, 7:42 PM.Comment

Reading this last bit over regarding the advisability of shooting 40S&W in your Glock 10mm, I realized I may have been a little heavy on sarcasm while not fully explaining why the author in the linked article's conclusion to not shoot 40 in your 10 is incorrect if you are shooting a Glock or similar handgun.
In fact, the author happened to pick a gun that exhibited two traits that have to be present before his primer piercing incidents might even occur.
The first is the gun must be feed the 40S&W round ahead of the extractor such that the round does indeed headspace on its case mouth. I sighted many thousands of flawless rounds shot through 4 different 10mm Glocks as evidence this isn't a likely outcome for a Glock. I realize while compelling evidence this is not definitive.
The second trait that must be present is the firing pin must be able to reach the primer when the 40S&W case is chambered ahead of the extractor. With a Glock, the firing pin is only going to get about halfway to the primer before it is halted. The gun will not fire with the case that far away from the breechface.
For those reading this that actually have a G20 or G29 and want to see it for themselves before actually shooting 40's, do this test. Remove your slide from your gun. Remove the RSA and barrel. Insert a spent 40S&W case in the chamber and reassemble the barrel and RSA into the slide, making sure the case is ahead of the extractor (hold the barrel and slide facing down while assembling). Now, holding the barrel up so the case falls back to where the extractor stops it from getting to the breechface and shine a light into the gap. Note how far the firing pin is from the primer. This is the definitive reason why the generalization about not shooting 40 in your 10mm Glock is incorrect. Pretty hard to pierce a primer with the firing pin not reaching it.
As far as loading 10mm ammo being the same cost as 40, it definitely is if you don't factor in that it is pretty easy to find range pickup 40S&W brass, while it is a very rare day when you find some 10mm brass. The availability of 40S&W on the floor at my local range makes loading both 40S&W and 10mm loads using that brass very cost effective for target practice loads.
I am not advocating loading your maximum effort 10mm loads using range pickup 40S&W brass, for these loads I only use virgin Starline brass. But for target practice (which I think the OP was asking about), 40S&W makes a very cost effective option (if you are shooting a Glock or any gun that exhibits similar traits to the Glock, and not a gun like the author of the linked article employed).
I hope that makes the facts a little more clear.When asked what qualities he most valued in his generals, Napoleon said, "give me lucky ones."Comment

Precision One Ammunition makes good ammo. Last time I bought some was pre-panic and they used to be way cheaper, but their current prices are not too bad. Post Sandy Hook their website went down and stayed down for many months. I just checked and they are back up and running and looks like they have 10mm in stock. They use Starline brass and I actually prefer this ammo to Underwood because it doesn't shoot quite as hot so it makes plinking a lot more enjoyable. http://www.precisiononeammunition.co...vqcssufo66k526Comment

Didn't want to create a new thread. Here is some testing on a good amount of 10mm loads done buy some guy on youtube.
From my research it appears that most of the common factory loads you will find in stores are "tamed" 10mm rounds. More like 40 S&W.
I've heard very good things about Underwood and decided to take the plunge on a few boxes myself. Have a 10mm in jail. My first 10mm and I've never shot 10mm before. The velocities of this round are pretty impressive which is why I decided to take the plunge.
Will it make me cry? Maybe I'll have someone record me crying after the first shot.Comment
