Can I fire 40 cal out of my 1006 or 1076?

[Triathloncoach]

I had read that my Glock Model 40 MOS 10mm can fire 40 cal as well. Can the 10XX series?

I really only ask because I don't own any 40 cal guns. I'm not necessarily looking to add calibers. But I've seen some great deals on 40 cal, the red haired step child caliber it seems, and maybe this is a way to justify picking one up.

Thanks

Both cartridges headspace on the case mouth and the 10 case is definitely longer by about 1/8 inch. I would think you would need a barrel swap to do this. I have guns in each caliber but I have never tried to "experiment". Googling seems to get different opinions on this topic.

Dana Safety Supply in Sugar Hill had a few used Glock, Walther, and Sig .40 S&W handguns in their showcase last week, $400.00 or less. A brand new Shield can be had even cheaper. I wouldn't risk damaging one of those third generation pistols or myself by shooting the incorrect ammo through them.

I tried it once with my S&W 1006. It worked fine for a whole clip of 40's. BTW in lots of autos the case rim head spaces on the extractor instead of the case mouth.......Therefore allowing the shorter case to fire & function.

We did discuss this a handful of months back and one poster made a very solid argument of why he does it and why he believes it is a non-issue.

Myself? I don't believe there is any risk to safety whatsoever, in any possible way. Really. Truly believe that. However, I cannot seem to be convinced that shooting .40cal in a 10xx pistol is not going to be hard on both the chamber and the extractor.

The extractor is a replaceable part, but it's far from "drop in" and I can promise you that you won't want to compromise your extractor. The chamber? That is pretty much officially a NON-replaceable part. If you foul it up, you will have turned your 10xx pistol in to a parts gun unless and until you happen to find a barrel. Good luck in that venture.

In the end, we're talking about a series of pistols that were made in the supply of just over 50,000 units. A simple risk-reward calculation should bring you to the conclusion that you risk too much for far too small a reward.

With that said... man, I love FREEDOM. I fully support folks that want to do anything (safe, legal, etc) with their handguns. I cannot place my passion and feelings on someone else's stuff. Therefore, since I certainly do believe there is no associated safety risk, I think you should try it if you really want to. Report back.

I used to do it all the time with a 1076. Never had a problem. Not a recommendation for you to do it, just answering the question posed. Yes, you can.

I suspect more semi auto's headspace on the extractor than we think. My own adventure with a Glock 35, a 40 S&W gun, using a 9mm conversion wolf barrel and the 40 mag, fed and fired 380's if the round fired in the chamber was 9mm. A 380 would not cycle the slide. It was all loose Tula ammo, and the 380's got put in a container of 9mm. However, I am going to keep the idea of a 40 in a 10, a 380 in a 9mm, or even a 38 Colt Super in a 357 Mag (it worked in my Blackhawk) in the only if I have no options and it is an emergency dept.

It'd be best done by having a 10xx & buying the appropriate
.40S&W barrel (40xx) & springs to use with it.
Might as well do it right, as opposed to half-assing it

 

[Sevens]

Hmmmm.
Except that isn't possible.

Bar-Sto made a short run of .40cal 10xx barrels, they are all but impossible to find these days.

A few years ago, maybe 5, I forget, member Bad Man One took orders here for a variety of replacement 10xx barrels including .40 S&W 5" barrels. The price was approximately $275.

The Gun Zone -- 10mm v. .40 S&W FAQ

I stray from this article in that I don't think the Omega is good to go either. If in doubt, just call or e-mail the firearm's manufacturer.

Bruce

P.S. If anybody gets a manufacturer to say, in writing, that it's ok to shoot .40's in a 10mm chambered autoloader, I'd like to be informed.

.380 was used for training by the instructors mixing it into mags of 9mm to practice malfunction drills for me a few years ago. They all fired, but could not cycle in a stock P226. I would think it would the same for 10mm/.40, yes they will fire, but expect it to become a single-shot manually loading pistol.

Due to the emasculated state of most current factory 10mm ammo, .40's will cycle the action, unfortunately.

Shouldn't a standard 40xx barrel fit in a 10xx,
as long as both are the same length??
Maybe a pic of both?

 

[robertrwalsh]

Just for the heck of it I did it once with 50 rounds. Worked fine. It is, however, not recommended.

 

[Sevens]

My 10xx is a 1006, 5" barrel. Both my .40's are 4006, 4" barrel, so I can't even attempt it to see but given the dimensional difference between the 9/.40 pistols and the much larger .45/10 pistols, I simply cannot imagine a barrel swap is possible.

Maybe someone else has looked in to it?

 

[44wheelman]

I heard a 4013 bbl will work in a 1066. I've thought of doing that myself... Load .40 cases with the 200 gr bullets hanging out closer to 10mm over all lengths with 10mm powder loads.

Why, cause I got a bucket of 40 brass, and a ziplock Baggie of 10 brass

While I haven't tried to swap them I think the length difference alone would rule out a swap. 10xx pistols were manufactured with 4 1/4" and 5" barrels. The longest production 40xx barrel was 4". The Performance Center made 5906 5" & 6" single action PPC pistols and 5906 5" TDA pistols so they might have made longer 40xx pistols but even if they did where would get one of the barrels cheap?

For a reloader, as long as you are not firing where you can not recover the brass, the cost savings from firing .40 S&W are minimal. Put me in the use the cartridge your gun was designed for camp.

Let me explain this, the 1/8" difference in casing length doesn't allow the 40S&W to properly headspace in a 10mm chamber. What happens is it is solely dependant on the extractor to hold the casing in place as the striker or firing pin strikes the primer. The bullet has to jump across the transition of the end of the chamber cut (which has a sharper edge) and can and does slice off bullet material so that bullet material can roll up and build up, plus carbon and powder fouling also makes the area dirty. This requires a good cleaning before any 10mm ammo is used as they can get stuck or not chamber as a result. There is always a possibility that the cartridge can get dislodged from the extractor and enter the chamber and it will not be removed by cycling the slide.
Yes some guns will hold the cartridge securely enough to allow it to fire the cartridges with a fair amount of reliability! However if you don't inspect and clean immediately the use, proper headspacing of 10mm ammo can be a serious issue as a result of the fouling!
If the 10mm cartridge is used prior to proper cleaning, they can become lodged tight! Stuck!
The case has to be able to expand enough to release the bullet without increases in pressure, any fouling that wedges the casing restricting the bullets release...pressure can increase and or KA-BOOM!

What is worse is the wear on the edges of the end of chamber cuts and the bullet can almost weld itself as it is scrapped off by that edge. It doesn't happen often but when it does, it a pain in the *** sometimes to clear and clean.

In a pinch and no other ammo is available it can be a viable alternative to get you out of a jam! I have fired the 40S&W from some of my guns and my doing so has provided me the insight that there are risk to doing so!

^This guy knows. He has been a full-throttle Smith & Wesson 10mm nut since these pistols debuted.

This guy -ALSO- owns a Bar-Sto .40cal conversion barrel and maybe if I follow him around a few forums and say really nice things about him, he'll leave it to me in his estate!
