From what I've seen, I think I'd be far more inclined to get an M&P over an XDM. But for now, I'm happy with my Glock 20.

I should probably read a review of the M&P that includes a history of the 10mm cartridge, beginning with the ancient Romans.

The 10mm began with a Centurion named Cooper. He wanted more arrows in his quiver so he opted for a slightly smaller arrowhead which enabled him to fit more without increasing quiver size.

The Bren cost is $1000 and the ammo with it cost $29,000.

H&K definitely comes to mind, but what I'm picturing is a pretty radical departure from any of their designs. There's rarely anything truly new in the gun world. I don't believe I've ever heard of any design using gas pressure to delay blowback and time the action, rather than operate it entirely.

The H&K P7M8 used a gas piston delay instead of direct blow back on a handgun. I know this because I was issued one and carried it for 12 years.

H&K has used these designs before. But I get you....you are looking for something new and innovative and I don't blame you.

I think we actually need something new in the world of design for good 10mm carbine. I've been kicking around an idea for awhile now. I really like the feel of my gas operated 10mm AR. It's just not reliable. I don't really care for the blowback designs.

So, I've been thinking of something similar to a delayed roller blowback design where the delay is augmented with gas pressure. That way the timing of the action is self adjusting to the power of the ammo. I think a gas piston driven delay system would keep enough junk out of the delaying roller(s) to make it feasible.

Anybody have a bunch of money or a really good machine shop?

Or call H&K. Delayed roller blowback designs are their specialty.

And as you said, bring a LOT of money $$.

I do think the 4" hits a sweet spot no one else fills with a 10mm.

The Glock 19 of the 10mm world.

They might be onto something with this concept.

The lever action makes good sense.

I had also written Ruger about the Mini-14 in 10mm. I even suggested they call it the "Mini-10." I received no answer from them.

Guess they aren't listening to us.

I'd like to see the Marlin Camp Carbine made and chambered for 10mm and using Glock mags...short, smooth, not bulky.  (they were originally chambered in 9mm and 45ACP)


Marlin Lever action in 10mm would also be a great one.  The 1894 or 336 style are nice.  I know Ranger Point will convert a Marlin but you need to supply the rifle for the expensive conversion. 

The Marlin Camp Carbine would be another great idea. The 10mm cartridge would be perfect for camp protection out of a long gun.

Is this DIY? 

Carcano Cavalry Carbine re barrelled to 10mm using Glock magazines.  I never shoot my Carcano, and the 6.5/7.35 Carcano case head is just .025" larger and the extractor has great purchase on a 10mm rim.  Maybe even 10mm Magnum...

Factory....I would love to see a Ruger Deerfield carbine in 10mm auto or 10mm magnum.

Could be DIY....why not.

The Carcano would be great. I also thought of and discussed with a 10mm enthusiast friend about the Ruger Deerfield. With all the renewed interest in 10mm you would think they (Ruger) would come out with something.

Not that I need another excuse to buy a long gun, but I would like to see some more options in 10mm out there.

How about a Mini-14 from Ruger in 10mm? Or a solid AR platform?

Some H&K versions in 10mm would be good to see as well.

Anyone else have any ideas on a 10mm long gun?

Just a note, on a 10mm forum anything less than 600 foot pounds of energy is considered weak by 10mm standards. Most 10mm enthusiasts appreciate ammo upwards to 700 foot pounds of energy.

Your hydrashocks will work fine for what you want. The FBI carried subsonic ammo in their MP5 10mm's for a decade.

Excellent. Glad you're back Shadow.

I have about 9000 rounds through my Glocks with no parts breakage. Obviously, not all of that is Underwood Ammo (not even close). It would be way too expensive. But I did shoot a fair amount of Underwood through them.

That having been said, my Kimber Eclipse shows some slide battering from the heavy loads (Underwood included).

As an aside note, I acquired the Kimber after the original date of this thread.

Congrats Patriot. Family first...

Glad we are back up and running.

Onward....

I wouldn't mind seeing those 200 grain Gold dots at Underwood velocities.
