I am uncomfortable with Sig single-shot pistol conversions

I am uncomfortable with Sig single-shot pistol conversions.

(If you have to ask 'which pistol', it doesn't apply to you and don't ask; it will be obvious to those thinking.)

I'm not gonna go into further details to avoid tilting hand.

If problems ensue they're readily defendable, but it's suboptimal situation.

If you're thinking of one, hold off.

People got all gun-horny - and improperly extrapolated these conversions from the AR single-shot pistol plan, which was carefully thought out for maximal compliance.

Some people just don't friggin' think, dammit.

[Adonlude]

So where does the difference lie btw the Sig and AR conversion?

Tell me about it.. I hate seeing those posts too!!

Do your concerns apply to AK single shot pistols as well?

[ptoguy2002]

If I am not mistaken, or correct me if I'm wrong:
An AR pistol starts life as a virgin receiver and is built in to a single shot pistol from the get go, by means of a bob sled mag and no gas tube. The action must be manually manipulated to chamber and eject casing, just like any other (real) single shot pistol. After its dros'd, you can semi auto it.

The sig pistol start life as a semi auto pistol, and how they disable the gas system so it won't recoil and eject a round, or otherwise make it into a single shot, I don't know. I think that might be what Bill is getting at.....

On a sig, the upper is the receiver too, not like an AR.

Remember also, disabling the gas system is not mandatory. Only an additional precaution.

So, does this concern apply to AK pistols purchased out of state and shipped to an intermediary for single shot conversion prior to shipment to Cali?

Um, no.

I believe that it's near mandatory to remove "semiautoness" and not have it risk being regarded as a 'broken' semiauto. I think you want far more clear delineation as to its S/S status than just a sled.

Think about what happens in a police evidence locker.

This single-shot pistol crap is starting to go sideways. People aren't following recipes that have been carefully thought out and have overextrapolated from the AR situation.

At least the good folks sending in S/S AR pistols are blocking gas port with 1/2" of gas tube installed upside down.

I don't see why people can't get the friggin' general concept thru extrapolation./

Have the damned gun away from semiauto status as much as possible and remove major semi componentry from gun and block gas port. How you block an AK with various designs I dunno, smart AK people can think that one up.

Remember, the gun has to
(1) be a single shot (use a maglocked sled)
(2) work and be useful (i.e, not be nonworking parts) as an S/S pistol;
(3) be safe to shoot (no hot gas on your hands thus blocked gas port);
(4) should not have useless semiauto hardware on it.

I would think that Bill's concerns apply to pretty much everything.

How do you convert a semi auto pistol, whether its AK or Sig, to single shot?
I understand how it'd be done on an AR with the gas tube, but you can't really do that on a sig or ak?

It can be done, now I'm hearing the word "permanent" being thrown around...
Go figure...

First off, for those wondering I'm pretty sure Bill's talking about the Sig 556 pistol, although at first I was thinking of the Sig 250 (very neat modular pistol system)

Either that, or folks were transferring them without the gas system disabled - just a single shot sled. Which would technically still be a single shot pistol, however the AR's are taking a second step and rendering it non semi.

I imagine if this is the case, the 'right answer' would be to rent an utterly mutilated single-shot Sig upper out that's had its gas system permanently nailed. The price would be about double the price of a Sig pistol, and you'd get the mutilated upper plus the normal one. I'm not sure how the gas piston is installed on a Sig, but if you were to unthread it, life should be pretty easy.

...then you'd return the mutilated upper for a refund of 1x the price of a Sig pistol.

The AR pistol stuff started out with the rental of pretty much permanently non-semi-auto uppers, and moved away from it a bit, and I think Bill would like it to move back there.

The big problem with rental is folks who didn't return the rented uppers - I know BSP lost theirs that way. The solution's simple - I'd just charge a high enough purchase price that if the customer doesn't return the rental, I make a profit.

Now, as for the AK's... while you could remove the gas piston, it helps align the bolt carrier. The way my PAR-1 is put together, I would almost go so far as to say that you couldn't really have a working non-semi-auto AK pistol without a gas piston for alignment purposes.

Good post grammaton76. The gas valve on the upper can be changed to not allow any gas to vent from the barrel. This is rather simple fix but would require a second "sealed" valve that will not vent onto the piston..

If an AK pistol is built from a rifle kit, the gas block is moved to the rear, which places it over a section of barrel that has not been drilled. To convert to semi, one would need to drill the new gas port.

On my flat build, I cut the gas piston, but left enough length that it would extend slightly into the gas block. This leaves enough length to attach the piston head if I ever convert it to semi.

It's a purdy gun . . . this is not mines of course
