Single Shot Conversions - What are the modifications?

[Jel]

Just curious as to what exactly happens to an off-roster semi-auto pistol when an 07FFL does the conversion to make it CA legal in single shot configuration.

From my understanding the barrel must be at least 6" long.

The overall gun needs to be 10.5" long.

The magazine modified so that it cannot accept any rounds or use a dummy magazine.

The magazine must some how be locked into the mag well.

Is this it?

For example, what exact parts would be needed to convert a Gen 4 Glock 22?

Thanks!

Long barrel. Replace mag release with non functioning lock. Dummy mag. Done.

I just DROS'd mine and took a pic. I'm going to post it in my thread Valkyrie Arms Shop Pics Page Three. Check it in a few minutes. Its a fairly long barrel and will only hold a single shot. Its easy to convert it back to stock. Valkyrie sent another slide with the barrel and put the original in the case. I was surprised they did that. They must trust that you send back the conversion kit.

I pressed the mag release and the mag came out.

Hmmm my mistake then. I kind of assumed they would've gone the mag lock route like they did on the 1911's/HK45. Dummy mag might be easier.

When I picked up my M&P 9 Pro, someone else in the shop noticed my gun in single shot and made a comment about there being a threaded barrel.

From what I understood, if my gun had a threaded barrel (to screw on an extension), my magazine had to be fixed. If I didn't have a threaded barrel, fixed mag might have not been needed.

I'd really like an expert on single shot conversions to confirm/deny that though.

12276.1. (a) Notwithstanding Section 12276, "assault weapon" shall also mean any of the following:
(4) A semiautomatic pistol that has the capacity to accept a detachable magazine and any one of the following:
(A) A threaded barrel, capable of accepting a flash suppressor, forward handgrip, or silencer.
(B) A second handgrip.
(C) A shroud that is attached to, or partially or completely encircles, the barrel that allows the bearer to fire the weapon without burning his or her hand, except a slide that encloses the barrel.
(D) The capacity to accept a detachable magazine at some location outside of the pistol grip.

Since it's single shot with magazine locked in the gun (cannot accept a detachable magazine), you can have a threaded barrel.

Right, I got that. But now I'm wondering in the other case:

1 piece barrel with 1 round detachable magazine. Does that meet the reqs of single shot exemption?

I doubt it. The gun is still capable of detachable magazines. You can put other magazines in it.

Close but no banana.

The mag must be not be a mag - it just "filler" and must have ZERO ROUND CAPACITY. For single-shot exempt considerations, the gun must only be able to chamber a round and not store ammo in a feeding position anywhere else.

Also, the single-shot pistol exemption should only be used for PISTOLS.

Use separate method for single-action REVOLVER exemption (removal of DA sear - most people will screw up guns). Note that there is not a 'single action exemption', it is only for SINGLE ACTION REVOLVERS.
