ok i just started the paperwork on a MAC M11A1 in 380, the seller also has the matching M11 RPB can to go with it he would sell me for $200.  is that a good can or would i be better off passing in order to get a newer one like a Coastal MIMS can or something like that?  I'm more interested in the Coastal as i can use that on an AR in 9mm as well as on the MAC and i hear that they are pretty quiet as well.

For $200 I'd get the RPB.  The can in the picture is more like the period correct item for the gun, and it is huge, so in .380 I really doubt it would not be effective.  

Also with MAC's the threads are coarse so if you don't hold onto the can, it might loosen while firing, so you kind of want the suppressor to be that size.

Maybe you could shoot it with the seller and make sure your happy with it.

gun is in texas, i'm in Cali and the gun is on the way to my CT dealer, can't shoot it.  i was mostly wondering if there are far better cans out there with today's technology as i've herd some of the older cans aren't even worth the transfer tax.  not sure, for $200 i might pick it up.  i will be running this primarily with a 9mm Lage upper and not so much in it's stock form shown above.

The Gemtech Viper is a better can.

I have a MAC M10 two stage suppressor like the one in your photograph and it works fine with new wipes. Some of these cans have been rebuilt over the years to eliminate the terminal wipes and this simplifies maintenance.  Nevertheless the Gemtech can has the look of the period can (although different in size), it has a better locking attachment system that keeps it from loosening, but it does cost more than $200, but you tend to get what you pay for.

I'd buy it just to keep them together for the next buyer, then I'd buy a modern can for performance. Not my money, though.

That's the dilemma I was having, don't want to break the package up but I don't have an extra $400 to spend on the can.  I could better use that money for a Lage upper, ammo or a better suppressor.  I also don't sell my guns, I have this problem where I buy something new with the idea of selling something to get some money back or break even kn what i just bought....  Then it never happens.  

Now does Gemtech make that can for the M11A1?

Get the can that comes with it. Looks cool and only costs you $400. Get a more efficient can down the road. Why not a Multimount?

You're gonna regret breaking that up later. You'll always have the opportunity to buy new cool toys but that setup right there is cool retro and probably has significant collector value.

The can pictured is the old, traditional two-stage style that you see in movies and typically associated with that gun.  It almost synonymous with MAC-10.  I'd say $200 is fair as long as you know you a buying it largely for looks.  There are new cans that are much more effective, much easier to maintain, much smaller, and much easier and appropriate to use on other barrels of what is usually a fairly small gun given the caliber.  There is a fairly good chance the can may be on the end of it's lifespan.  Look at it this way, the seller is simply recouping his transfer tax, so the can to him is basically worthless.  If it was any other accessory, many of these older systems would really be considered disposable if it wasn't for the paperwork and cost.  A good quality modern can will last indefinately.  If funds permit, I would buy it, clean it up a bit, and not shoot it, and get a separate modern suppressor that you can use for various guns.  Some might say why not just buy a fake suppressor, but that's another issue.

BTW, in moving from a socialist state to a free state, I did pretty much what I suggested above, but I did have some extra cash at the time.

Christ on a pogo-stick why would you NOT spend the money to get a GOOD can?  Get a Gemtech Viper and enjoy life.  Best mount.  Best sound performance.  Best size and weight.  People recommending other "period" solutions are delusional.

I guess it depends on how worthless the original can is.  At its size it would be hard to screw it up so bad that it would not sound good on a .380.  I don't think that's delusional.  

Maybe people are thinking about 9mm performance.  The .380 is a pretty small round for that rather gigantic can.  If it sounds good, and costs $200, why would anyone think spending $700 is a "better deal".

I'm not familiar with the 2 calibers but is there that much difference between 380 and 9mm?

95gr @ 980fps vs 115gr @ 1300fps
200ft/lbs vs 420ft/lbs

OP, to clarify my earlier post, I'm not suggesting that you shoot the old can or not get a new one. I'm just pointing out the fact that you might not get a chance to get an old style can later on.

That means you're working with a can bigger than a full size contemporary 9mm pistol can, and dealing with a pistol round that needs a suppressor 1/2 the size of a 9mm suppressor (all other things being equal... which they are not) the can is low tech no doubt, but the volume should more than make up for that, resulting in a strong sound reduction.  (In fact the can may well be a can designed for 9mm that is used here on the .380).  

I still say get the guy to demo it for you- more than likely it will work fine and you'll be saving yourself a lot of money.

This is a 3.7 ounce AWC suppressor on a .380 PPK I believe it is fired wet, but it gives you the idea of how huge that can is for being able to effectively reduce sound.

Coastal.

I sent you a PM why.  If you have any interest in a 9mm AR, one of the locals is building a real beast with these cans under the hand guards.  Just move the can around as-needed.

I always wanted to get an old SIONICS 2-stage can when I had my MAC10.  It just looks right.

However, I don't know that I'd pay a lot for one.  I'd get one if I could find it for $100 or less.   $200 - probably not.  You might try to talk the seller into lowering the price.  After all, what's he going to do with it?

Why not a Multimount?

Because while the MM is an excellent can, it doesn't have the volume you want for a high-speed subgun can.  I don't shoot my Trident-9 (essentially the same size as the MM) on my M11/9 any more.  Way too much gas blowback.  It gets me choking and tearing up.  Need a full face-mask to be able to shoot that sucker.

I save the Trident for the Uzi and pistols and use the Bowers can on the M11/9.

Would the blow back as bad on a low-speed subgun (i.e. M11 w/ Lage upper)?

It may help, due to the heavier bolt keeping the chamber sealed longer.  However, the gun I use has a TASK-style slowfire conversion with an 11 oz. buffer.  So the Lage upper may not help. It's worth trying if you have the parts.

I have HAD a GT Viper as well. It worked great but after I got a Lage I sold it.

It's more than twice the price and it's limited to just the one configuration on the gun.
If he's buying a Lage upper, they're threaded 1/2x28. The Viper won't fit any longer.

entirely possible for an M11A1.

However, on my PS M10/45, with Lage upper, it rocks.

In all honesty buy the can it is $200 and when you want to shoot it in the original config it will be fun.   Worth the $400.

You can get the Lage in any thread and his .22 upper as well. Mine are threaded for the Mac threads, 3/4 by whatever they are. It still burns my eyes with the Viper and the Lage upper.

ok now i get why the subgun cans are marketed and look different than the regular pistol cans.  they are twice the size not because they have to hold up to FA fire but they need the extra volume inside to be able to take the high rate of fire.  a pistol can can't do that so it blows more back down the barrel, do they both have the same amount of sound reduction though?
