Why no 357 mag semi auto rifle?

[Bainter1212]

Yep....the M1 carbine fits the bill, but they are too expensive nowadays.
Would love to have an m1 in 10mm

Glock 10mm Carbine

Of course......a Glock Carbine in 10MM would spark my interest.......

It already exists. It's made by Thureon Defense:

My guess is that folks can shoot .38'special and light .357 loads with a lever gun.

Semi autos can be finicky with calipers where the power factor can change a lot.

Straight blow-back system in 10mm just isn't a sound idea.... Not for me anyway

10 mm Glock carbine exists all right, but that ain't it. This is the real deal, build it on your real Glock: http://www.mechtechsys.com/what_is.php

Yep^^

Because RUGER hasn't made one... yet.

The 18.5" Bbl'ed Mini-14, re-chambered and modified to accept the RUGER 77/357 rotary magazine, would be an awesome woods rifle.

W/ the demise of MARLIN into the stinkin' quagmire of corporate profit hell...

...the market is wide open, and ripe for plunderin'.

I'd buy Three(3) right out of the chute.

Rimmed vs. Rimless cartridge most likely.

I'm no where near "knowledged" in this specific question, but from what I've read/heard guys discuss who know well more about that cartrage usually tend to say what was said above.

The cartridge design is the biggest limitation/set back.

Not really... there are indeed semiauto rifles with detachable box magazines that use rimmed cartridges. It's an issue, but not one that's impossible to deal with.

I know there are plenty of 357 mag lever rifle out there, but why haven't anyone build a 357 mag semi auto rifle (I can't find one anywhere)? I think 357 mag is one of the best pistol caliber to benefit out of a longer barrel.

Although there are a few people that would buy them (like me), there are not enough people that want one to allow manufacturers to mass produce them inexpensively. Expensive guns don't sell.

The only place a 357 rifle/carbine is popular right now is in cowboy action shooting with leverguns. People that want a lightweight and light recoiling rifle with (relatively) low ammo cost may want a 357 levergun. People who don't want a levergun, would just get a 9mm AR or similar pistol caliber carbine.

Reloaded 357 Magnum is cheap. Factory 357 Magnum is not. I can't see too many people blasting 200 rounds of factory 357 in a single afternoon, like I could see them do with 9mm, 40S&W, or 45ACP.

A 357SIG chambered AR type rifle would be interesting.

Here you go, probably the closest you will find

I could build a gen 4 glock carbine in 10mm from off the shelf parts and a custom barrel... not cheap but it should be pretty easy..... could run featureless

While not a semi auto, you might be able to find a way to turn a SA .357 revolving carbine into a DA??????

I used to have a Ruger Police Carbine in .40: https://en.wikipedia.org/wiki/Ruger_Police_Carbine

Great carbine, built like a tank. Featureless, no bullet button required. They also made them in 9 mm. I always thought it would be cool to make on in .357 Sig. Probably not too hard - start with the .40 version, get a 9mm barrel, get someone to ream out the chamber to .357 Sig specs, and your off.

I know .357 Sig is not the same as .357 Mag. At the top end, .357 Mag can be loaded much hotter. At the low, end, if you tried to load the .357 Sig to .38 Special specs, it probably wouldn't cycle the action. Still, its kind of what the OP was talking about, and probably not too hard to do, if you can find the PC4 carbine and the PC9 barrel.

Except it wouldn't satisfy the folks who are trying to minimize the number of different cartridges they keep on hand, which is likely to be a portion of the small number of people asking for a .357 mag semiauto rifle. Unless a company like ruger really sees a demand for such a rifle and can price it appropriately, it's not going to happen for less than a couple grand.

Something else to think about with the rest of what I posted previously in this thread; when was the last time anyone saw development of a new firearm in .357? I don't mean a new model of a revolver with a different frame size, or a new takedown version of a lever gun. Yeah there's the desert eagle, from the 80's. I know it's still around, but it was decades ago now that serious money was spent on R&D for it. The coonan 1911 came out in the early 80's if I remember right? Nothing else really comes to mind other than the Medusa M-47 revolver. So in 30 years or so, no one seems to have established that there is enough of a market to do anything really "new" with the .357, I doubt it'll happen any time soon or ever(except maybe in some boutique or limited run fashion that will flop in the marketplace after a brief rush).
