ATTN. 10XX Auto Owners, Production Has Started - .40 S&W & .357 SIG Barrels

[Screwball]

So at one point in time there were .40 barrels made for a 1006? Were they factory made?

Not factory... they were produced by BarSto. I do know that a member of 10mmTalk has a 9x25mm Dillon barrel, which I believe was also made by them.

Most of the past attempts to get a .40 or .357 SIG barrel made has been through them, but they want a minimum of fifty barrels to be purchased (not for all types, like a total of both .40 and .357, but fifty of each type). When you try to get that together on the internet, it is impossible to get fifty people. You may get some that say yes, but not respond when you are ready... which would screw your run if you were just around fifty.

How about a 30 Luger barrel for the model 39?

 

[Chuck Jones]

I got a .357 sig barrel for my 4046 from bar-sto before they stopped making them. It works like a champ! Swap barrels, add a heavier spring for the .357 and voila. Point of aim differences are not that bad and one day I'll switch to Novak adjustable sights and that will be that. A perfect 2 caliber gun.

I think it would be a great idea for the 10XX series but what about magazines to handle the shorter cartridge length of .40 S&W and 357 sig?

+1 on the .30 Luger 39XX BTW!

I would definitely be interested in .40 S&W and .357 Sig barrels for my 1006.
A .357 Sig barrel for a Shorty .40 would be cool, too.

 

[snowcat]

I would take a 357 sig for the 1006 and the 1076, and maybe for the 4006 also. If you go for it count me in.

40 S&W & 357 Sig

I'm interested in both for my 1006! Have a 357 Sig in the works for my Model 22 Glock! Let me know if/when production is nearing. Assuming true drop in fit!

 

[ceptor781]

I'd be in for a 40S&W barrel for 1006 and 1066 depending on price.

 

[jeff4863]

Let me know whe you have them ready.I want one for the 1006 ,just want the .40 in 5". let me know when they are ready

 

[Class III]

Tell me where to send the check and it's in the mail. I "NEED" a 40 and 357 Bbl for my 1066.

Works fine in other 10mm platforms. In fact, in my Delta Elite my 10mm mags work better than the 40's with the spacer.

 

[Jetpilot007]

I am interested in a 357 Sig barrel for my 1076s (I own 2 FBI Issued 1076s). If its a go please let me know.

 

[Screwball]

Bumping it up... since I had to go a few pages back to find it.

 

[pretell]

I would be very interested in a .40 S&W barrel for my 1006.

 

[tocohillsguy]

Let me know when you're ready to roll.

 

[FirebirdV8]

If you made a run of .40 S&W for the 1066/76/86 barrel lengths I would be interested in one.

 

[Frank Black]

I would be very interested in a .40 S&W barrel for my 1006.

Got in late on this (hopefully, not too late), but I too would be VERY interested in a 5" .40S&W tube for my 1006.

 

[Frank Black]

For conversions like that, you would use standard magazines.

The .40 round is a shortened 10mm, so it will fit in the magazine with some space to spare. The .357 would be similar since it uses a bottlenecked .40 casing. Glock 20 conversions work the same way, and back when .40 1006 barrels were produced, that is how they were ran.

The magazines would not need to be modified. Also, 4006 magazine would not work, since they are double-stacked and the 10mm magazines are single-stacked.

I agree regarding the magazines. The 10XX-series mags should work and feed fine for the .40S&W, .357Sig & 9x25Dillon cartridges, just as the stock 10mm mags for the Glock 20 & 29 work without a hitch w/ those rounds. 10mm fans on GT and elsewhere have posted repeatedly about having NO issues with feeding.

These rounds are all 10mm case-derivatives anyway, so for extraction and ejection purposes the critical "back-end" dimensions are identical. Plus, the polished, integral ramp of 10XX-series barrels should work in favor of smooth feeding off the mags, not against it.

In 1911 guns, I've read about IPSC/IDPA guys who, when they interchange their 10mm barrels for .40 tubes, "long-load" their .40 reloads (i.e., increase the COAL a bit) to ensure consistent feeding. But my understanding was they still were using a stock 10mm mag.

Just FYI ...

BadManOne,

It'd be terrific if you turned this into an on-going second career -- after retirement.

Please place the emphasis on "on-going"!

Any way you shuffle it, it's a terrific idea -- provided they all drop in.

Keep us posted!

The 10XX-series mags should work and feed fine for the .40S&W, .357Sig & 9x25Dillon cartridges, just as the stock 10mm mags for the Glock 20 & 29 work without a hitch w/ those rounds.

With that being said, a member on 10mm Talk has both a .40 and 9x25 Dillon barrel (both were BarSto). He posted a few times in the project threads over the years, and never made any mention of issues.

Don't think there was a .357 SIG barrel made, but being a bottlenecked round just like the 9x25, it should feed just fine.

Really hope this goes down. I'm looking at moving to an organization that uses .357 SIG, and wouldn't mind seeing what kind of performance I can get out of the round. Converting is better than buying myself a P229 in it (I don’t have a .40 gun to convert).

Progress report on the 9/40 conversion barrels

I have contacted quite a few barrel manufactures about producing some 9 m.m. and .40 S&W rifled blanks because
they can do the gun drilling and button riffling more efficiently than I can.
They seem to prefer to use alloy steels (4140 types), where I’m asking for 400 series Stainless Steels.
I am still waiting for more quotes to come in.

In the interim I found a Bar-Sto barrel in 9 m.m. X 23 m.m. from a forum member and purchased it.
The reason is partly that I wanted to see the quality, fit and finish of a Bar-Sto (Drop-in?).
The other reason is that I had found 7 - 50 round boxes (at a good price) of 125 gr. Winchester Silvertips HP's in 9 m.m. X 23 m.m
with the thoughts of de-capping them to use the brass for my .356 TSW reloads.
Well, after de-capping one box, what a pain in the butt that was.
I got to thinking about shooting the ammo rather than de-capping them and happen to find the Bar-Sto barrel by chance.
Was I ever surprised when I received it? It had to be re-worked quite a bit, it was definitely not a "drop-in".
The barrel locking lug in front of the chamber hood that seats into the slide when in battery was not cut deep enough by .024” on the diameter compared to my factory barrels.
The location of the breech face lug on top was binding on the slide breech face and was also way out of square to the thru bore.
I ground .010” to fit leaving .002” clearance during lock-up. Stock S&W barrel and slide seem to be .004-.008 clearance.
The .204 diameter pin on the slide lock lever that holds the assembly all together and contacts an area under the bottom lug and
controls the position that the slide locates forward lock-up relative to the back of the frame was off.
It had to be reground with a matching radius, I had to push it back an additional .032” for the back of the slide to line up.
The chamber was also way out of spec and it was re-bored in a CNC Lathe to SAAMI Specs.
Now it's ready to go to the range.
