I own a carbine in AR furniture chambered in 9mm.

I like it, it accepts glock mags which is nice. Its called JRC (just right carbine)

If we're talking ballistics, 9x19 can almost reach .357 Mag velocities out of a 16" barrel iirc. Definitely adds a bit of "umph" to the cartridge over a standard 4" barrel.

>>32433198

That's more or less correct, but highly dependent on the load & bullet.

Check:
http://www.ballisticsbytheinch.com/9luger.html
http://www.ballisticsbytheinch.com/357mag.html

It should also be noted that 9x19mm tends to start losing speed past the 14"-15" mark. In some cases, 16" is already suboptimal (due to faster burning powder used in pistol cartridges).

>>32433253
How about 9mm loads designed for rifles? I have heard of people getting over 700 ft lbs

>>32433510

You kinda need to make sure your weapon was designed to handle it.

>>32433540
>>32433510
Most modern 9x19 firearms are designed with 9mm NATO/+P SD rounds in mind, obliviously YMMV, verify.

>>32433697
>Most modern 9x19 firearms are designed with 9mm NATO/+P SD rounds in mind, obliviously YMMV, verify.

Yes, but 9mm NATO isn't special in any way? It's the defecto standard. And most european commercial loads tend to be about equal to NATO loads. Anything below is considered training ammo.

Yes, +P & +P+ is going a step above. And you should expect higher wear & tear on guns that eat a steady diet of that.
But NATO loads are nothing special at all.

What we were talking about were SMG loads though (common in a few militaries), or specific rifle loads (usually hand loads). It's quite possible that cheapo civilian carbines are not really built for extended use of the significantly hotter SMG loads.

Did someone say AR-9?

>>32433033
Depends on the load. Regular old 115gr FMJ loses velocity. I've seen some anecdotes with some guys getting 1700FPS with handloads, but not factory.

>>32433779
Like the famous israeli black tip ammo. Wasn't AP but designed for the Uzi.

I tired finding info on SMG loads but didn't have much luck, about all I found was the Israeli stuff.

I think the problem you have for an AR at least and many 9mm smgs is it is blowback. That limits your ability to push the cartridge too far because you can easily get into unsafe pressures and the action opening too quick. You'd a strong f action to really take advantage of a rifle 9mm load imo.

Is it safe to shoot +p in an AR-9?

No. Just wrong. Stop posting.

Surprisingly accurate, which is kind of a natural advantage to a shoulder fired firearm. They'll bust cans at 50 yards all day without a miss. I've also read about people using hot 9mm hollowpoint handloads as deer rounds.

It gains almost no velocity because its usually loaded with quickly burning powder. The only major handgun calibers that gain much from rifle length barrels are .357 and .44 mag

Gaining an additional 50% speed isn't "gaining much" in your experience?

>>32435150
Looks like Marlin Camp Carbines.

They were blowback carbines in pistol calibers, 9mm Luger, and .45ACP, the 9mm using S&W 9mm pistol magazines (3rd gen/5900 series), and the .45 using 1911 magazines.

They're plain blowback carbines, but overall kind of nice. Something to note is that they are required to have a neoprene or other synthetic recoil buffer in them, otherwise the impact of the bolt slamming into the back of the receiver will slowly cause the wooden stock to split.

These buffers can dry out and wither with age, and stop absorbing impact, thus picking up an old one and shooting it is ill advised until it can have it's buffer inspected, and optionally replaced. Many of these have had their stocks cracked over the years, which is why they're often found put in Choate folding stocksets (not too bad), or sometimes in Muzzelite bullpup kits (dogshit).

I heard it used to be difficult to find replacement buffers, but they're supposed to be available now, they're basically just a solid piece of synthetic that sits in place and absorbs impact, so they're not expensive to make or buy (buying a couple to keep as spares wouldn't be a bad idea)

Pic related is a 9mm one fit in a Choate stock, and shown next to it is a Smith & Wesson 3rd gen 9mm pistol, along with various magazines these two guns share.

Another nice PCC, this is the Ruger Police Carbine, available in 9mm Luger (as well as .40S&W).

It's straight-blowback, BUT, the weight of the bolt is cleverly distributed, a lot of it sliding underneath the barrel, you don't have the entire weight of the bolt back in the receiver, so it balances quite nicely for the kind of weapon it is. Think like the Chiappa 9mm M1 Carbine, but not fucking awful, or like an Uzi, except the bolt doesn't telescope over the barrel.

Build quality is nice (it's hard to fuck up a blowback, but lord knows some people try, like Chiappa), and it uses Ruger P80/P90 series pistol magazines, of which the market is absolutely lousy with. These are in themselves quite ok pistols, designed to be a bit of a budget gun, but still nice, think something between a S&W 5906 and a Hi-Point, mostly leaning towards the S&W, if you already have a P85 pistol or whatever, you already have magazine, otherwise, there are a ton on GunBroker, both Ruger factory made magazines, and MecGar magazines (outstanding quality, and fitting two more rounds while being the same size as the old Ruger mags).
I'm not sure what magazines the .40 caliber carbine uses.

Drawback is that Ruger no longer make these (apparently they just didn't sell all that well), so they go up a bit in value, expect to pay somewhere north of $700 for one in used condition.

9mm NATO is equivalent to commercial 124 grain +P
Standard commercial 9mm is a lower pressure loading compared to NATO

>>32436202
What does that offer over a traditional pistol?

>>32437162
Large magazines and a forward point of contact, along with longer sight radius, more velocity and longer range, easier recoil control.

Also if that was a real stock, another point of contact, allowing you to aim it from the shoulder.

>>32436876
I have a fake shroud but it's ugly and adds a weird amount of weight up front that makes the gun swing farther than I want it to when I move from target to target

I personally like it the way it is (prefer flush mags over the extendo clipazines too).

Any fags recommend decent budget irons for a 9mm carbine?

So, theoretically, if one were to build a full fun Sten Mk.2 with a 13" barrel and give it a decent stock and/or foreground to control the recoil, would that make it a decently effective full fun carbine you can make in your garage?

>>32437384
Sure. Conventional firearms are a mature technology. Sure, advances in materials, ballistics, optics, and ergonomics, have improved the effectiveness of modern firearms... but many antiquated designs still see frequent use today, and obviously, military firearms have been utilizing the same cartridges for at least a half century, and in some cases, even a full century.

If you can hose out a room with a 9mm (no stoppages) the guys getting hit won't care if it was from a STEN or an evo.

>>32437384
Sure.

Just make sure that you get your paperwork and shit in order before starting, the ATF are not kind to people's dogs.

MAC10 and MAC11 derivatives have been made by a lot of companies over the years (some people even build their own, they're very simple), the original firm went out of business in the 80's, anyone can make one based on that design.

Some are quite decent, some aren't so good.
Many just have bad magazines (made out of Zytel), which don't last for all that long, even a half-baked old Cobray M11/9 can be made to run pretty reliably with good steel mags.

By far, old original RPB open-bolt guns (both semi-auto onlys and machineguns), SWD machineguns, as well as modern updated clones by MPA (rifles and pistols firing from closed-bolt,), seem to be among the better performing ones.

>>32437169

Doesn't balance as well.
Doesn't have the same length of barrel (not as much reach or velocity)
Doesn't have multiple points of contact.
Recoils more.
Less attachment points.

I have shot 9mm NATO from my AR9 running a standard 9mm CMMG buffer and a .308 buffer spring and like $1.75 in the buffer tube. The ejection was noticeably harsher and if i was going to run a steady diet of it i would go with a heavier buffer.

>>32439362
>preference
It simply will not balance as well as something with a forward handguard or VFG, but I guess that's the whole point of contact thing.

>>you can't extend the barrel
Are there 8" barrels for Glock 17s which you can also mount a silencer on, while still having the gun cycle reliably? I mean I know there's Nielsen devices, but it's starting to be a pretty awkward package now, especially with all that shit wobbling up and down, can you guarantee that this won't interfere with cycling at this point?

>>you can't get a glock stock sbr or a brace
You can, but that's tax stamps, which may not be available in all states.
Also mounting VFGs on Glocks has never been quite safe (they break off).

>>I need 60 things to improve my shooting
I don't think wanting accessories is unreasonable, if you make use of them.

It's more that you can fit a suppressor on a gun with a fixed barrel, and it'll stay put (especially if we're talking a QD suppressor on a flash-hider).
Then there's fitting a VFG (something which isn't a good idea for a Glock), then a light and/or laser, which would start taking up a lot of space on a pistol, but which can be set on the sides on the MPX.

If you want an optic on a Glock, it's a pretty cumbersome setup, while on an MPX (or any similar weapon), you just attach it, or fitting scope rings, straight on the top rail.

If looking at an SBR, the stock on an MPX collapses compactly along the sides of the gun, like an MP5, there isn't really any setup like that commonly available for a Glock to my knowledge.

Looking at full-auto, the Glock is really a pretty iffy weapon for most people, 2 or less points of contacts (because a VFG on a Glock 18 is an even worse idea), not to talk about a rate of fire which will drain even a 33rd mag in a hurry.

>All would still cost less than a mpx
Yeah and a Glock would be cheaper than a HK94 SBR, but a Glock also can't fill the same role for me.

There isn't really anything wrong with most of their products. The old Mini-14 series weren't so well designed, Bill Ruger was, despite a pretty cunning firearms designer, not the most business minded, and kind of a big fudd (the whole AWB thing).

That, however, is long gone, as their previous CEO has spent the last 10 years growing the company, it's product lines and quality, reversing things Bill did wrong (not selling hicap mags), or doing things better which he could have, but didn't (such as the Mini-14, or general treatment of workers).

The company would really have not done nearly as well as it is doing now if it was still under Bill, even if he contributed a lot of it's foundation.

>>32439825
Nothing wrong with investment castings, if used correctly, look at the Super Redhawks, they're built like tanks and have a lockup like a bank-vault, the amount of abuse they can take, and the kind of insane handloads you can run through Ruger's revolvers in general (even the old Security Six), is notable.

Think so.

They're available in both 92FS and PX4 flavor, so pick the one you feel is more convenient, if you have either of these pistols, or just find it's easier/cheaper to find mags for them.

MecGar 20rd mags barely protrude (like maybe two inches) from the grip on these (or on the pistols), so that would offer you quite a lot of firepower while not making the package of the weapon bigger.
They of course also make excellent 30rd mags.

>>32440041

>>32440041
>They're available in both 92FS and PX4 flavor, so pick the one you feel is more convenient
Plus they also make inserts for the magazine wells that allow you to swap back and forth. Mine was originally a Px4 version but when I bought it (secondhand) the guy had converted it to 92 mags.
