PPSh 41 build--Shotgun News

- Start date
First thing, hugh i sent you a pm, well atleast tried a couple times! If you got the first one, ignore the second, if you got neither, message me, and i can email you my response, or will try sending it again 
.
On topic, i have never heard of a open bolt semi auto... But thats just me i guess, just seems like the cfc would claim it too easy to convert FA, wouldn't it be?
The american laws don't require the reduced id i don't think, but builds that incorporate that tend to have higher success in approval rates. The BATF don't really care too much how you do it, as long as the original full auto bolt doesn't fit into your semi auto receiver.
But, the point being, a reduced id receiver may help whoever here's doing this build, get their "investment" approved. When you only got one chance, you want to go through all the precautions you can, as to assure your success. Impress the rcmp with all the dumb precautions you've installed, as to preventing the thing from going full auto again!
Found this site, maybe it can come in handy?

edit: Just read this, and thought i would share. It was Century that used a "striker" setup, that was more prone to jamming and/or malfunction, than the "hammer" setup used by other manufacturers. Century now uses hammers, but incase anyone was considering this "striker" design, i guess you should avoid it?

That was the first gun I ever knew - great guns with the right ammo
If I could ever persuade my dad I may just strip that bugger down and copy the trigger system from it..... watch the rcmp deny it when they realise it's a design from an already permitted rimfire!

The Gevarm trigger mechanism is very simple and clever; quite elegant from a design standpoint. It has only two main pieces - the trigger and the sear. It does not have a disconnector tripped by the bolt. The pivot holes for these pieces are not round, but oval. The sear is held in contact with the trigger by the bolt pressing against it. As soon as the bolt is released, the sear disengages from the trigger and resets. When the bolt re-engages the sear, the sear can re-engage the trigger.
I don't think you should make any assumptions about what the RCMP might or might not accept. If you have a serious proposal with specific details contact them.

He will be back....like a bad cold he always returns sooner or later. With Duncer, it is usually sooner, and his charming obnoxious personality will always reveal him soon enough.
Do you have contact info?
Or pictures?
I can't visualise it, but I'm thinking this is definitely a good route to go...
Which "Small arms of the World"? I did a quick search on Amazon and found books by that name by: -Daren, -Smith, -Chant, -Crawford and other.

I believe the oval pivot holes in the trigger mech are similar to the design of the Sterling trigger mechs.....been a while since I was into one, but it seems to me the C1 smg trigger mech used this method. Problem with any of these open bolt systems is you would have to weld the trigger mech components in, since removal of them will result in a full auto/runaway gun. Virtually any trigger system on a open bolt gun is easy to defeat. Time will tell whether the RCMP will accept such a system for what it is or whether they will judge it for what it can (easily) be. As such, I await for there to be a CFC/RCMP tested and approved open bolt Canadian made gun. The "########" frankengun (Spencer) creations, as many of us are aware, are not presently acknowledged by the CFC as existing in their open bolt form, so have managed to be FRT'd and sold under the radar, and by circumventing the lab testing process.
Same can be said about a lot of semi auto guns. but i do see your point. we are home builders and have to prove are designs to the government, and it seems most of them there think we are out to break the law.
Anyone know a verifier with access to the online FRT? It would be easy to do a FRT search for ######## as manufacturer. I believe that the latest disc version is Sept. '08. The SAS version of the Sten is there, as built and documented by a number of individuals.
It is worth mentionning that it is an offence under the Firearms Act to supply incorrect or false information when registering a firearm.

I actually saw a recommendation on that book on another forum and got confused too - there are lots of them!
If it's only a two part trigger system, like a gevarm, then you'd basically have a tube with a spring and bolt in it if you removed the trigger.... which would be easier to make than a legal design, so not make sense to me why anyone would go through the trouble of registering it and making it legal, and therefore null... then again, maybe I'm wanting it to work too much.
I suspect if you made it very clear that it was a design copied from an already legal gun, that they might realise it's pretty legit.
I guess the other alternative would be an open bolt design where the trigger releases a bolt assembly that housed a free floating firing pin, and the bolt would trip a release on the hammer once it went into battery. Seems you'd need to get your timing very exact though, or lean on the side of caution and have it late, or you might get the hammer releasing before the cartridge is fully in the chamber/battery...
Edit - any chance one of those $99 norcarev clones could be recruited for this? Seems with alteration there are a lot of parts in one of those that could be pressed into service... and yes, I know it's a very very different gun... but it might be worth a thought.
