Sig 1911 Conversion Kit has threaded Barrel?

[krystmas]

Hi all,

Was thinking about getting a sig 1911 conversion kit so I can shoot .22, but noticed in an installation video they said the conversion kit has a threaded barrel. Does that mean I'm not allowed to purchase it because of the threaded barrel?

We have very interesting rules in this state.

You could have the threads turned off then bond the thread cap to the barrel. That is probably what I would do. Because no, you cannot install a threaded barrel on a semi auto pistol with a removable magazine.

I appreciate the reply.
I think the kit I'm looking at has a cap on the threads so... I just gorilla glue the cap onto the threads then?

Use some Roxette

If you leave the threads on there, per DOJ the device covering them must be pin and welded making it permanent. But DOJ has done lesser things than that like on a certain 22 pistol they approved for sale in CA. So depending who you talk to and what day of the week you get it, their answer is as good as any unless you get it signed in black & white with DOJ letterhead.

In regards to the Walther P22, what was allowed was an emergency fix that was approved due to CA DOJ error of not being aware the pistol had a threaded barrel in the first place. So far, Walther is the only manufacturer that was officially allowed to perform a quick fix of epoxying on a smooth thread protector/cap, so that it could be considered "permanently affixed".

However, per CA DOJ BOF, if a CA LE forensic/gun unit can remove the muzzle device that was affixed in a manner that does not meet the CA regulations for permanently attachment [11 CCR 5471(d)], then it will be treated as a threaded barrel.



California Code of Regulations Title 11 Divison 5 Chapter 39 Article 2 Section 5471
(d) “Barrel length” means the length of the barrel measured as follows: Without consideration of any extensions or protrusions rearward of the closed bolt or breech-face the approved procedure for measuring barrel length is to measure from the closed bolt (or breech-face) to the furthermost end of the barrel or permanently attached muzzle device. Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100o F) silver soldering, or blind pinning with the pin head welded over. Barrels are measured by inserting a dowel rod into the barrel until the rod stops against the closed bolt or breech-face. The rod is then marked at the furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and measured.

You MUST HAVE THE THREADS MACHINED AWAY FIRST. Then you can proceed to bond the cap in place.

Step 1. Machine away the threads
Step 2. Bond the cap in place.

Do not skip a step

And Gorilla Glue has no place in this project.

It is possible that high temp silver solder brazing may work without removing the threads, but until the parts are in hand and the materials identified, it is hard to say for sure.

Since this thread cap becomes the barrel end and interfaces with the slide bushing, it is important that there is no material or defects added outside the cap and barrel.

Use some Roxette

But not before the threads have been machined away

According to the youtube it has a cap on the threads when it arrives so maybe the pin method would be best?
California is so much fun

I have a 22 conversion on my Sig 1911 without the threads.

That video is 7 years old, check the new ones.

And here's a new one. No threads.

Has to be pinned or welded. Glue isn't forever.

If the barrel has no threads why do you need a cap?
