These are neat little shotguns, especially popular with the law enforcement crowd back in the '70s.

I understand that durability is something of an issue, and parts are hard to come by.  I don't see these for sale much anymore.  There was one at a gunshow about a year ago that looked to be about 85%, with a $650 asking price, but it was a Model B.

Lucky Dog!

I would love to have one of those! I heard that Choate once made mag extentions for this shotgun as it only holds 3 rounds...

Just be sure to keep your non-trigger hand out of the way of the muzzle!

A local shop has TWO on display [but not for sale].  One's stainless and the other is blued.

I'll ask about field stripping when I'm in tomorrow.

The original bullpup shot gun was designed by a Beverly Hills Detective in the mid 60's.  I was out there in 1967, and saw a local TV news story on his gun. I think he sold the idea to High Standard.

Major differences between the A and B model were:
A Model
Flashlight in an AR-15 type carry handle with rather crude emergency sights on top.
A standard Cocking handle on the bolt.

B Model
Flashlight was a standard type light, with an attached mount, and could be removed when not needed.
Had a BAR/FAL/BREN gun type rotating carry handle, also removable.
Had a folding front sight on the barrel, and a notch rear sight just behind the carry handle.
Had a cocking handle on the left side of the gun as well as the standard cocking handle on the bolt.

These were designed to work only with high brass, full power buckshot loads. They will usually NOT work with standard low power loads.

The 10-A and 10-B unfortunatly had rather serious reliability problems, and this, more than anything else is what ended it's production.  Even with heavy loads, reliability is usually not very good.

There was a company (not Choate) that made a Model 10-specific magazine extension kit, and I had one on my 10-B.

Sorry, it's been years since I had a B model,  I can't remember how to disassemble them, but I found an exploded view in an older Gun Parts catalog, and I remember you had to unscrew the magazine tube as one step.
There are holes in the end of the tube for a nail or punch to help unscrew it.

I do know that these are sought after by collectors, and bring a high price.

I strongly suspect that a letter to the NRA will get you full disassembly instructions.

There is a really good history on the HS 10's somewhere, I think maybe in Thomas Swearngen's Combat Shotguns book.  Can't find it right now, but will continue to look when I get home later.  Good history and pics of many varients.  Nice find, nice neighbor.

Checked my library at home, can't find my copy of Combat Shotguns by Thomas Swearengen.  Think that's were article is on the HS 10's.  Also seem to recall there was a decent article on them in one of the early issues of Fighting Firearms magazine, but not sure.  I'll let you know if I am able to locate it.
