Unlocking the Stock PPS43

fred333 · Apr 15, 2014

Does anyone have experience reconfiguring the deactivated folded stock on a PPS43-C to make it fully functional again?

I just ordered one of these semi-auto pistols of Beelzebub and I'd like to know what's required--both in parts and legalities--to end up with a properly functioning stock (I've no interest in returning it to automatic function....I just wanna be able to use the stock to shoot the thing in a safe manner).

You will need to register it as a SBR before you do that, won't you?

That would def make it an SBR. That's why they deactivated the folding stock in the first place. $200 tax stamp.

Needs to be SBR'd. Someone will come along soon to chime in on their methods of re-activating the stock. I'm in the process of trying to SBR mine.

Form 1 with $200 check to ATF (less than 16" barrel). I believe that some machining is necessary for the stock's locking mechanism in the receiver. I am not sure if the stock is reusable after being welded closed. I think I have some spare stocks off parts kits if you want to buy one as a functioning assembly.

This isn't C&R, but I think you're like me an just really like the C&R section

either has to be registered a a short barrel rifle first

or

the barrel must be made longer, by permanently attaching an extension to make the barrel over 16" and the entire firearm longer than md's legal limit.

Okay, now we're getting somewhere.
Re the form: Is Form 1 the one that's titled "Application to Make and Register a Firearm"? If so, I've got a copy, but I seem to recall the form required the firearm's serial number, which I won't have until I receive the gun. Or do you know if I can apply without the serial number?

Re the stock parts: I should probably wait 'til I receive the gun to see what's needed before I buy anything, but I'm definitely interested in the parts kit. Can you give me any details re cost and parts compliment of the kit?
Thank you, Nate.

I am going to do this too....after I get my tax stamp.

I remember reading something were all you have to do is swap with a functioning stock from a parts kit. I also ordered a parts kit, Centerfire systems for $50 (no mag of course) and should have that in a few days. For the same price you can get one with a surplus 35 rnd mag but will need to be sent out of state of course.

I am getting a trust set up and then will do the stamp then swap parts.

Shooting it without the stock is not the easiest thing which is why everyone puts one of the slings on and uses that to add a bit of stability.

Yeah, I'm definitely a vintage kinda guy (and not just re firearms).

Technically, having originally been manufactured in the 40s, the gun should be C&R. But, sadly, because the conversion (from sub-machine gun to semi-auto pistol) was done recently, Maryland now defines these as modern handguns and lists them on the MD Handgun Roster of regulated firearms. So, in order to buy one, I need to go through the same criminalizing routine that any other law-abiding Maryland citizen must deal with to benefit from our constitutionally-protected and inalienable right to keep (but generally not bear!) a gun. :sad20:

The one I have is a newly manufactured receiver (Pioneer Arms imported by I.O) that fires from a closed bolt. I had heard that many of the earlier models were built using old 40's era parts (barrels, etc. but new receivers). I was unable to confirm that.

Per Wiki (If you believe them):
"In 2010, Pioneer Arms, of Radom, Poland, began producing a semi-auto only version of the PPS design, called the PPS-43c. The gun, sold with its stock fixed in the closed position, is legally considered a pistol in the United States. The gun is of a closed bolt, hammer fired, blow back operated design as opposed to the open-bolt design of the PPS-43. According to a report in the July 20, 2012 edition of Shotgun News, the PPS-43C utilizes many parts from unissued PPS-43 submachine guns mounted on new PPS-43C receivers."

You're probably right. Unfortunately, the dealer, Classic, wouldn't ship the mags to an out-of-state friend, so I'll have to acquire them separately (perhaps at the Chantilly show in a coupla weeks).

I am getting a trust set up and then will do the stamp then swap parts.

I'll have to look into the trust option as well. Is there site that details the costs and procedure?

You can say that again. I shot a friend's PPS and to say it's unwieldy is putting it mildly. Disabling the stock on these guns is just another example of how ignorantly out-of-touch our law makers are. I mean, to take a very stable rifle and turn it into an unstable pistol in an effort to "make them less dangerous" is....well, I think anyone here knows where I'm going with this.

My understanding is that all of these "C" PPS43s are a mixture of old (the basic gun) and new (the conversion) parts.

By the way, for anyone who's unfamiliar, this is the guilty party and I'd love to see photos of the PPSs you guys already own:

eddiek2000 · Apr 15, 2014

I have one in the arsenal. I also purchased a kit just in case I want to sir it and unlock the stock. If you do a google, you can find info about unlocking the stock. I thought it would be just easier to swap the parts.

Wha? Thats like saying an AR15 built w/ *vintage* Colt parts but on a new Spikes receiver should be C&R. The PPS43C receiver is brand new.

Anyway, here is my pic. You only need one part from the kit to convert it - the button. I just made a new one (and bought a spring from Ace hardware.)

Nice. What are you feeding it? How does it shoot? How long have you had the stamp? Sorry for all of the Q's. Kinda like a kid in a candy store. I might need to up my timeframe for the stamp.

I was under the impression they only modify the bolt and trigger assembly, leaving the OEM frame/receiver/barrel. No?

Nice, but whaddya do about the spot welds? Did you grind them off or did you have to replace some other parts?

I think only the early versions were spot welded. The later versions had the button modified so it wouldn't work.

ohen cepel · Apr 15, 2014

I think they have varied some as to when they were imported and how the mods were made. I looked at mine a bit and it didn't look like an easy swap of parts.

Rick at Glade Hill did some conversions and IIRC he also said it was a bit more to it than he thought.

I am on the fence about doing it. I think it's neat but just not sure its worth the hassle and tax stamp.
