HERA GCC SMG kit

When I first heard of this, I thought it sounded interesting. Had a look at their website. I was curious and emailed them inquiring about the possibility of purchase. Didn't receive the courtesy of a reply. Had another look at the photos, and, like Klunk and Lazarus2000 thought that something like this could be made using either aluminum tube or channels.
There are lots of 1911 style pistols. How many Norcs have been sold in the last few years? A 1911 pistol could be mounted into the rectangular tube using the slidestop and safety holes, with spacers to keep the pistol centered. Incorporate an independent hammer block safety in the design. Do without an automatic hold open, add a manual one to the charging mechanism. Charging mechanism could be ambi, non-reciprocating.
Perhaps Choate would sell folding hinge assemblies. I have a scrapper hinge unit to play with. Given the overall length, I don't know how necessary a folder would be.
Flat bottomed Weaver pattern rail stock is readily available.
 
" .... welding a square steel tube to a scope rail and spraying it black would work, but something less prone to spontaneous self-disassembly ... "

Actually, some of the commercially made Glock scope mounts are made of MUNIMULA, so attaching some alloy tubing to an existing mount would work for a quick and dirty prototype. Welding alloy is NOT "minimal skill", so I've ruled this out for anything but proof of concept prototyping. The Aimtech mount has a neat alloy body, but comes with a very short plastic insert, with cross screw, to take the rail mount.

The FAB PLASTIC Glock scope mount has a neat spring loaded push pin quick disconnect way to attach to the Glock rail, and a much longer rail attachment surface, but the plastic body will flex considerably, and the expected stress from the extra foot or so of stock leverage, does not promise longevity, or accuracy.

An alloy split in the middle clamp on rail riser looks like a great solution for the rail mount part, but the usual picatinny spec female part of the riser block must be opened up to fit the Glock receiver rails.

All of these designs require more support at the back of the pistol, which is where the replacement screw in slide stop support comes in. There is also some other support points to consider ....
the cutout on the bottom of the grip is convenient and well proven with the usual Glock stocks.
Etc, etc, etc ....
yadayadayada.

The final solution will be elegantly simple ...
but elegant simplicity is usually the result of a lot of intensive R&D, and good design work at the beginning.

So, the BIG question for me is how important is QUICK DISCONNECT to the design?

If you can snap a Glock in and out, with no tools, in just seconds, then this seems like an obvious advantage to me.

Or is it?

If you have to screw in at the rail, and screw in at the slide stop pin, is this a major disadvantage?

Enquiring minds want to know?

Under what circumstances would converting a pistol into a carbine quickly be advantages? Its either a pistol or a carbine - trying to be both (with no real benefits) usually results in compromises.

What are you going to do with the stock when you convert it back to a pistol? Leave it strapped to your body? If you are going to do this why not just leave it in carbine mode?

Don't see the need for quick conversion and associated expense of this feature.

Lazerus,

I'm back on the ground in Canada now, and have access to my glock and other "accessories"

Any progress, or should I work something up on my end and see what I can create :)

You guys need any solid modeling, CAM work, or CNC machining done, let me know.

This thing looks idiot simple. Why not mill it out of a solid bar of aluminum?

Anyone shot with one of these adapters from http://www.endotactical.com

Thought id ask in here as well cause its a similar product, if anyone had any feedback
 
I have been quiet to this point but I think it’s time I start saying something. Over the last several months I’ve been working on my own design for a GLOCK carbine and I’m almost ready to start production. I don’t want to give anything away but the first prototype has been built and tested. The second production ready prototype should be done by the end of the month. All I can say is it’s a combination of machined and laser cut parts. Once the production ready model is finished I’ll post pic’s.

If you need anyone to do some free testing/reviews.........LET ME KNOW!:D I am in London ON, frequent EESA........frequently, LOL

I’m also a member of EESA and that’s where I did the testing! I will need people’s feedback. If you bring the ammunition I’ll let you shoot to your heart’s content. PM Sent!
