"Hush Puppy" Rear Sight Wings & Update

dvelleux · Dec 10, 2015

Folks,

Attached to this post is a kinda crappy image of the revised rear sight wings for the Mark 22 Mod 0 pistol replica. While the windage hole may be slightly off, I do not wish to risk weakening the metal on the wings' rear edge...

Also, I spoke to a gunsmith near me who is willing to try to make the slide lock for this pistol. We will try making a 3-D printed prototype first, then try to do the slide lock from 4140 steel...

Keep the faith...

Folks,

In an effort to be as complete as possible, I want to start working on the blueprints for the detachable shoulder stock for the "hush Puppy." I have a few issues in doing that, since I use Microsoft VISIO 2007 as my drawing program, and it is NOT very user-friendly for drawing curve-linear lines, such as how the back-strap of the 39-2 curves to fit into the shooter's palm. Does anyone have any ideas on how to best overcome this obstacle without having to buy software that costs thousands of dollars?

Images of the "hush puppy" and stock are attached...

Seems you have some pretty good pics there. You know I'd try simply scaling up an image of the stock until you get the right size 1:1 and start taking measurements right off the picture. It doesn't look like a terribly complex part to make. I'd think a precision bender like a small Diacro would handle the stock tubing, a mill to fab the rest and tig to put it together.

I often wing it, make a sketch on a old envelop or if I get really fancy, some graph paper, then start making chips.

If you're really set on a computer solution there are a lot of open source CAD programs out there that are pretty well regarded and often free.

Looks like a real neat project you have going on, I'm subscribing to this thread.

Cheers
Bill

Seems like the stock attachment would be pretty simple. Just remove the backstrap and use it as a pattern.

As for a CAD program, I think there is a free trial version of Sketch up available, but even with this program which is advertised to be "simple" to learn, the learning curve will be long.

Well I have no idea how I missed all that

terrific stuff.

By the way...Did you get all the chamber and faux can plugs sorted out yet?

I use this stuff to make turn non-marring punches all the time.
Black Delrin® (more accurately termed acetal resin)

Machines easily and is very strong. It wouldn't take but a few minutes to turn a 9mm dummy round with a o-ring groove.

Bill,

I bought a small set of 9mm snap caps I will have turned to make a pair into the barrel chamber plus. I already bought some vinyl tubing caps for the barrel muzzle cap. Still need to figure out a replica suppressor chamber cap...

Regarding the hardest item, the local gunsmith reported back to me in the affirmative that he can make the slide lock!!! We are going to make a 3-D prototype before making chips fly. He is starting to determine a price for it now...

The true rebirth of the "hush puppy" is coming up...

Hey! Glad to see this project back on track. I personally would make that shoulder stock my lowest priority. I think only a couple were ever made and they were not issued. The one you pictured is with an Airsoft gun, of course, and the holster is missing the mag pouch on the front of it. I think you've got the hardest problem solved, i.e. the sights. What progress have you made on a threaded barrel?

dvelleux · Dec 21, 2015

Kevin,

I have tried searching for a 5" barrel supplier, but the best solution seems to be an extension to lengthen the barrel to 5". That same gunsmith is now cutting back a barrel bushing, then he will silver solder it into a slide for me...

There are a few images form a Small Arms of the the World book with the shoulder stock. Also, I have not seen an image of the holster with a pouch for a spare mag on it, only one to hold the pistol with suppressor attached...

For my pistol, I have a spare backstrap I am going to have drilled and tapped for 1/4"-20, so it at least looks like it will accept a shoulder stock. Once my pistol is done, I am going to make an engraved walnut presentation box for the pistol and an "accessory kit" in the box. Should be cool to see...

Folks,

BMCM (Bill) has joined the team to recreate the chamber plugs for the faux suppressor and the barrel chamber. I am certain he will do well...

This whole project fascinates me. I have a shooting coach who was in the "Teams" in the '90s, and they still had some in the armory in Virginia.

kwill1911 · Dec 21, 2015

Here is one of the refill kits:

I just have a few odds and ends but if you want to recreate the wipes I can give you measurements.

Kevin,

Thanks for the offer, but the way our current government is functioning, even possessing a wipe may be grounds for taking away one's Second Amendment right!

I think if you can create a drawing with the measurements of the barrel chamber plugs, that would be a huge help for Bill to be accurate. With your vast connections, do you know anyone who has the chamber plug for the suppressor to reverse engineer?

kwill1911 · Dec 22, 2015

Actually my photo shows a magazine, a muzzle plug, a barrel cap and a chamber plug. I don't have the back end cap plug. Is that what you mean by the chamber plug for the suppressor?

dvelleux · Dec 22, 2015

Kevin,

Yes, the plug for the threaded end of the suppressor with a lanyard...

dvelleux · Dec 22, 2015

Folks,

Just spoke with the gunsmith a bit ago. He came up with a great idea that will actually IMPROVE the slide lock above what S&W did on the originals. He suggested using a "D-hole" for where the pivot pin connects both sides of the slide lock. A "D-hole" is like a circle, but with a flattened spot on one side, thus if a matching "D-hole" is created on both sides of the slide lock, then both sides act in sync with each other...

Additionally, BMCM has already created a FANTASTIC copy of the chamber plug. Please review the attached images, but I think we already have a winner!!!

Folks,

Merry Christmas to all on this forum and their families. May the peace of the season be upon you all...

I am hoping a lawyer will see this and chime in. No, not regarding my first statement, but whatever...

With regard to the faux Mark 3 suppressor, I would like to know if we duplicated the muzzle plug, would inserting it into a recess on the faux can' muzzle be considered like the muzzle cap for the M16 rifle, or do we have to deal with a whole new ballgame?

I feel since the muzzle plug would be merely inserted into its recess to keep water out, much like the M16 muzzle cap, the ATF would not care. HOWEVER, due to the "interesting times" in which we live, what would the muzzle plug be considered?

Please feel free to respond...

The best option is to write a letter to the ATF firearms technology branch and get a ruling from them in writing. Anything else is akin to playing with fffire ie. federal firearms felony.

Contact info is here https://www.atf.gov/firearms/firearms-and-ammunition-technology

You'll need to explain exactly what your are trying to accomplish and attach the prints. Answering inquiries just like this is what their job is. Basically you'd be asking for the ATF to rule that your faux can design is in fact not a suppressor under current law. Without the ruling in place you can still conceivably get in a bind. Even without the plastic muzzle plug in place the faux can may still be deemed a suppressor by an LE officer and seized and then sent the the aforementioned Firearms Technology Branch for legal determination.

Once you have the ruling in writing, assuming it is in your favor, You would keep a copy with the "Hush Puppy" set anytime you take it out to play so you have documentation that everything is legal in the event of an inquiry by local LE.

Merry Christmas
Cheers
Bill

BTW, I seem to recall there being some legal issues with attaching a shoulder stock to a pistol as well. When writing or call the ATF you might inquire about that too.

Good idea. My former next door neighbor has a full WW I era civilian .30 Luger kit complete with 32 round drum, shoulder stock and shoulder holster kit. It has a case, and includes the original receipt from 1918 when it was purchased from a big sporting goods outfitter in Germany, and brought back to the States. Along with it is a letter from 1973 from the ATF ruling that his kit is exempt from the shoulder stock ban since it predates the ban, and was in the states prior to the ban. Grandfathered through.

You can purchase the replica black powder long barreled revolvers with detacheable stocks because black powder firearms are exempt from the law.
