Another SMG design

From outward appearances, it's probably blowback from open bolt?

By the way, I've always wondered - if they sold it without the stock could we load another 5 cartridges in?

P.S., sorry it's clearly not a new design, just new to me.

It's gotta be an open bolt

wouldn't it be classed as pistol if it was designed to be fired with or without the folder attached?

Can we even get that thing up here to begin with?

Are you liooking to import one? You may need to see if they are classified as an UZI variant with the FRT.

The gringo pages say this:

"Fires with a closed bolt
Strong and rugged design guarantees resistance and durability
Works perfectly with all 9 mm caliber makes and brands
Excellent grouping and accuracy
Perfectly balanced and easy handling
Very compact, easily field striped without any tools
Grip and thumb safety
Adjustable rear sight
Folding stock
Bolt remains open after last shot is fired
Allows flashlight or laser-sight mounting
Water resistant "

Also, in the FAQ :

"9.- Where can I find the HM-3-S semi-automatic submachine-gun?
This product’s is exclusively for our security squads, The Army, and The Navy; therefore, it’s sale is restricted."

It's more a MAC variant than an UZI

Not looking to buy, just interested in it for it's obscurity.

Actually it hasn't much in common at all with those to designs other than the fact the hm-3 uses a telescopic bolt and has a mag-well/pistol grip.

That appears to be a semi-automatic variant of the Mendoza design from Peru.
The barrel is actually a type of "spine" which receives (receiver?) all other parts.
And the "body work" which one would normally assume would be the receiver has no structural value at all and only serves to keep out dust and what not.

I believe that a draw back to the full auto smg version was the fact that the recoil spring is wrapped around the barrel and within the telescopic breach thus rapidly heating up and becoming soft and thus prone to failure.
Semi-auto wouldn't have this problem of course.

I'm not sure I like it... but then again, any new "evil" looking balck gun available in Canada would be good news!
