John Jr Posted July 7, 2009 Report Share Posted July 7, 2009 As most of you know, I have been into silencers now for a while, but have seen no viable option for a TSMG silencer. Anyone make one yet? Thanks John Jr www.silencerresearch.com Link to comment Share on other sites More sharing options...

Anyone make one yet? Thanks John Jr www.silencerresearch.com John, welcome to The Board! Always like to see newbies come in.... I've not seen anything other than the vintage one I bid on some time ago.... Crap everyone gets their panties in a wad when people try to upgrade the sight system I can only imagine their despair if you try to attach a silencer.

james m Posted July 7, 2009 Report Share Posted July 7, 2009 I can't imagine it would be a terribly difficult undertaking as I see suppressed UZIs and MP5s at my club all the time. These are amazingly quiet with new state-of-the-art suppressors which are available today. IMO: The lack of availablity of Thompsons and, I expect the reluctance to thread the original barrel on one, are probably the main reasons I haven't seen any to date.

Thanks John Jr www.silencerresearch.com John Jr, Haven't seen you around for awhile...good to see you back! I know of no company or person that makes them for the TSMG, but I have seen a couple of "home-brew" versions on the internet? I guess finding a full-auto rated .45 can would be the first step to fitting one to a Tommy! Does anyone know off hand if regular .45 ball ammo shoots sub-sonic out of a 10.5" barrel? This make a BIG difference on just how silent a TSMG could be! Norm Link to comment Share on other sites More sharing options...

deerslayer Posted July 7, 2009 Report Share Posted July 7, 2009 I took an old semi auto barrel that had a bulge near the muzzle and wacked off about 8 inches. I have a coastal can, and sent them the barrel to be threaded to fit the can. Haven't got the barrel back yet but as soon as it comes back, I'll screw it onto a gun and report the results.

emmagee1917 Posted July 7, 2009 Report Share Posted July 7, 2009 In years past , someone made a quick-change bbl set-up for the Thompsons. It used a recessed set screw from underneath which hit the threads of the bbl. That part of the thread was filed flat to lock into the screw. You just backed out the screw and unscrewed the bbl and screwed in the other and retighted the screw. Chris Link to comment Share on other sites More sharing options...
giantpanda4 Posted July 7, 2009 Report Share Posted July 7, 2009 JJ - where you been? Suppressor! Not Silencer! By now you know I mean Doug Richardson.... and he is right too. Doug has a whole publication on Thompson supressors. I know there are a few of them floating around - but I have never seen one in person of his design. Only one I saw was on a 22 at a TCA show several years ago. Addictive.... Link to comment Share on other sites More sharing options...
TD. Posted July 8, 2009 Report Share Posted July 8, 2009 John Jr. Glad to have you back on the Board. I hope you still tune in from time to time. How is Sam doing? I bet he is still enjoying that first Thompson! Please give him my regards. If the Thompson had a quick change barrel, I believe this would be a great accessory. Unfortunately, this is not the case. I have seen where PK can make a quick change barrel for a Thompson, but only those owners with a West Hurley or shooter grade Colt's or WWII Thompson's would dare go this route as it does modify the receiver just a little bit. I believe PhilOhio has also modified his Thompson for a quick change barrel. Changing a Thompson barrel is not a lot of trouble if one has the Richardson tools, but this does add to the cost of having another barrel with a silencer. I have an old book by J. David Truby, Silencers, Snipers and Assassins, that has some information on the Thompson & M3 Grease Gun with silencers. I bet you have it as it was published in 1972. The book states the Thompson is a "noisy gun and unsuited to a silencer." I would have to withhold my judgment until I could actually witness the operation of a Thompson with a silencer. However, I do agree the open bolt action of the Thompson would probably be a bit noisy. Please join us more often. If you don't have this book, I will be glad to photocopy the pages on the Thompson and Grease Gun and send them to you. TD. Link to comment Share on other sites More sharing options...
Shattered Posted July 8, 2009 Report Share Posted July 8, 2009 I did the quick change barrel mod on my WH M1A1 as the previous owner had already cut the receiver to accept unmodified drums. So originality be damned, now I don't worry about it and it only cost $1700 a couple years ago anyhow. SO now I can play. I did the 9mm conversion and use Soumi 36 rd stick mags, 50 round Suomi coffin mags and 71 round Suomi drums. With the 9mm mags separated from the gun you cannot tell it isn't a 45. I picked up the .40 cal barrel from PK and have that now running 90% as well. Mag needs a bit more work, but it's getting there. The 7.62x25 conversion is almost finished. Uses the same bolt and ejector as the 9mm setup and just requires a barrel change from 9mm to x25. The x25 system uses Ppsh-43 sticks and Ppsh 72 round drums. Time required to go from 45acp to 9mm/7.62x25 is about 4 minutes as it requires a bolt swap. So now I'm thinkin'.... I've got plenty of 9mm barrels and a 9mm can not really doing anything. http://www.hunt101.com/data/500/DSC011781.JPG Link to comment Share on other sites More sharing options...

emmagee1917 Posted July 9, 2009 Report Share Posted July 9, 2009 Never had or shot a supressed Thompson. I do have a Ciener (sp?) on a 45 M3 greasegun. The sound of it firing is about like an empty gun feeding brass cased dummies. It is quieter than closing the bolt on an empty gun because the brass case prvents metal to metal bolt/bbl contact. My first shot out of this at the range , I let the bolt drop on an empty chamber to get an idea of how quiet it was compared to justt the gun action. I then put in the mag and aimed at a target 50-75 yds out. I tapped the trigger , and the bolt fell , and I thought it failed to pick up a round! Then the brass case hit the table , then the "thunk" of the cardboard came back from down range ! A quick glance confirmed the bolt was locked back. WOW!!! This blew me away.

AlanDavid Posted July 10, 2009 Report Share Posted July 10, 2009 The British developed a suppressor for the Thompson in WW2. I am pretty sure it was developed by S.O.E, but it could have been a Royal Small Arms Factory Enfield design. I have seen a photo - which I will try and locate - it looks a bit ungainly. It was never put into production, as the Mk2S STEN was an easier option. The STEN was silenced, as opposed to suppressed.

emmagee1917 Posted July 10, 2009 Report Share Posted July 10, 2009 First is possible , second is impossible unless you are floating in a vacuum because there will always be some noise. Chris Link to comment Share on other sites More sharing options...
Gould Posted July 11, 2009 Report Share Posted July 11, 2009 The fact that the firearm is not "silent" notwithstanding; "silencer" is the correct legal term for the device. It's too bad it is so difficult to change barrels on the TSMG. I am torn between the classic look of my WHM1 and my desire to suppress every thing I own. It's also too bad I bought the thing last March...I have a lot more into it than Shattered has into his and I'm not about to start drilling holes into it just yet. Maybe I need an adapter than attaches to the front sight somehow...hmmm. Gould Link to comment Share on other sites More sharing options...
jim c 351 Posted July 11, 2009 Report Share Posted July 11, 2009 What's the difference between "suppressed" and "silenced?" Thanks. If you hear a sonic crack upon firing you have a suppressor. If what you hear sounds like a fat man blowing a fart, you have a silencer. Jim C Link to comment Share on other sites More sharing options...

Merry Ploughboy Posted July 13, 2009 Report Share Posted July 13, 2009 Hill's "American Legend" book has a photo of a WWII integrally suppressed British Thompson. I don't have a copy of that book or his new one so I can't give a page and plate number citation. Old Auto Ordnance catalogs listed a Maxim (looks like a Model 1910) design for the Thompson. The Maxim suppressor replaced the Cutts compensator. David Albert probably has a catalog with the proper page. IIRC, a few years ago (maybe 2005) at a TCA Shoot which I did not attend somebody had one of the Maxim suppressors. The gun was apparently rather quiet. There is nothing magic about a Thompson vis a vis any other .45 carbine size gun. Any properly designed .45 suppressor that has threads sized the same as the comp will work, just make sure it is rifle or carbine and full auto rated. IIRC, Gemtech and AAC both used to make suppressors for the HK USC. With the correct threads either may work. I think those designs were both HK three-lug connections so an adapter would be required. Any auto or semi auto gun will have some mechanical noise and any blow back gun will have a fair amount of breech noise. In some respects, 0.45 is harder to suppress than smaller calibers simply because the hole is bigger so more noise can and does escape; however, as a .45 is generally loaded well below sonic speed and the gas pressure from the .45 is pretty well down by the time the 10.5 in barrel length does its job, the suppressor can usually be pretty effective. I have no affiliation with Gemtech or AAC. I do not own products from either company. Not legal advice, MHO, YMMV, etc. Link to comment Share on other sites More sharing options...
emmagee1917 Posted July 14, 2009 Report Share Posted July 14, 2009 I have a WW2 M65 Reising USMC training rifle. I believe it was suppressed by USMC armorers to kill critters in the island supply dumps without waking any marines who had been pulled back to there from the front lines ( such as they were). Some units " appropriated" some to kill 2-legged rats , ergo the name "rat rifle". I believe they orig. had maxim suppressors on them. Although I stummbled into a rifle , I have been unable to come up with an orig. suppressor. Therefore I had a modern-guts copy made. The point is , though , that when using CCI mini-mags I get the sonic crack , when I use sub-sonic ammo , I don't. Therefore using that as the "difference" between a silencer and suppressor is wrong. Silencer is the old term used. Because it cannot achieve true silence , the term suppressor was coined to be more accurate. Now days , using the term silencer is "politically incorrect" . It's akin to telling your DI your rifle is a gun or that a ship is a boat in the navy. Chris Link to comment Share on other sites More sharing options...

Chris Chris, When I made the comment about the difference between a silencer and a suppressor it was meant to inject a little hummor into this post. As usual , I failed. Heres my take on the subject. A silencer doesn't totally silence a firearm, but attempts to do so. A suppressor doesn't totally suppress a firearm, but attempts to do so. A can is where you go to take a shit. A silencer is a silencer because Hiram Maxim says so. A Thompson is a submachine gun because John Thompson says so. Suppressor, machine pistol, machine carbine, can , ect ect ect, all for people who like to play word games , in a attempt to impress the newbees. What the hell, everyone needs a hobby.
