Talk:Submachine gun

message: I'm not a firearms expert by any means, but the carbine article defines carbines as being larger than SMG's in the intro section. Additionally, the personal defense weapon article refers to PDW's as hybrids between SMG's and carbines. Since I can't read Russian, I can't find the basis for defining an SMG as a carbine in citation 1; additionally, linguistic discrepancies may exist in the definition of a carbine.
Unless somebody can bring a citation defining SMG's as carbines, I would advise removing the definition of them as such.

replies: text: I realize a typical SMG is lighter and shorter than your average carbine, but the point of the lead is to succinctly explain the article subject. A carbine is just a shortened rifle; there's no other connotation. Thus, using the term "pistol-caliber carbine" is the easiest way to explain that an SMG is a shoulder-fired weapon that's shorter and lighter than a rifle but chambered in a pistol caliber. The British call SMGs "machine carbines", if that's corroborative at all. Vintovka Dragunova (talk) 17:20, 20 August 2014 (UTC)
thread_title: Definition as Carbine

message: "A submachine gun (SMG) is a firearm that combines the automatic fire of a machine gun with the cartridge of a pistol, and is usually between the two in weight and size. An assault rifle, in contrast, uses an intermediate-power cartridge with more power than a pistol but less than a standard rifle or battle rifle." (wikipedia)
The P-90 does NOT use a pistol cartridge, it uses the arguably smallest rifle cartridge ever put into standardized use. As such, whatever it IS, it is NOT a "submachinegun" any more than the L85A1 bullpup rifle was adopted by the British Army L85A1 or the french FAMAS.65.102.43.164 (talk) 15:58, 24 August 2009 (UTC)
replies: text: The 5.7x28 is not a rifle round. It's a purpose-built PDW round, like the 4.6x30 used by the MP7, designed to produce rifle-like velocities from a pistol-sized cartridge. In power and range, it falls above most pistol calibers but well below most military rifle calibers. The firing platform however, is unequivocally an SMG in form and function.

message: I altered the Villar Perosa reference to LMG; though it used a 9mm pistol round, its tactical use indicates that was its intent, not SMG.  See Military Smallarms of the 20h Century & The Encyclopedia of 20h Century Weapons & Warfare.  --squadfifteen, 23/11/05
The round is close to a 9mm short (.380ACP) it is a failure of doctrine rather than the weapon, apart from aircraft weapon it was issued as a twin mounting for postal cycles. The Italian front was mountainous which I think discouraged the use of the short range weapons. - Breeze  —Preceding unsigned comment added by 188.221.207.100 (talk) 20:11, 1 October 2010 (UTC)

message: I came to this page looking for information on the basic workings of submachineguns. My impression is that, like automatic pistols, they do not lock their breech and that, like automatic most anything, they are actuated by gas pressure. I could be wrong both on the pistols and on the SMGs.
A related question is the heat budget. How long can a SMG fire at auto rate with a good chance of not jamming? What is done to help (besides keeping the magazines small)? How is the exterior kept cool enough not to burn hands? Are there exceptions?
Many thanks in advance.

In general, subguns do fire form a open breech. Some, like the MP-5, do not, but they are the exception. Most larger automatic pistols (9x19mm and above) do in fact lock their breech. Additionally, almost all submachine guns are, like automatic pistols, recoil operated. A gas system would be unnecessarily complex. 
As for your second question, you would find your self hard pressed to overheat any magazine fed weapon under normal circumstances. Unless one feeds mag after mag into it a SMG won't overheat enough to effect anything other than accuracy. To really overheat a gun it has to be belt fed. As for barrels, one does not usually hold onto the barrel of a gun that is being fired, because they do get hot. In the future, this is not really the place to put questions like this. A gun forum would probably be a better setting. SirBob42 13:21, 14 April 2007 (UTC)

Uhm could you tell me which police force uses actual submachine guns so I can avoid that country ?
Or do you mean some kind of a special force and not the regular police ? Taw 20:22, 15 July 2006 (UTC)

text: Virtually every police force in the world has submachine guns at their disposal. They are of course not used on a day to day basis but rather in heightened risk situations (like chases after armed bank robbers or whenever there's a terror alert). Those police forces that do not use submachine guns, generally use assault rifles instead. --Sus scrofa 09:50, 28 August 2006 (UTC)

message: More like "a list of my favorite SMGs".  Who decides what is famous or not and what is their criterion?  The Suomi?!  Its article is only four paragraphs long.  Pull your heads out of your asses.—The preceding unsigned comment was added by 67.79.10.226 (talk • contribs) 10:44, 2006 July 29  (UTC)
:That is the problem with fame, how to quantify it.  No, this list should not be a list arbitrarily created by people adding their personal favorite SMG, but it should include SMGs that are historicaly important, such as the Tommy Gun and some of the others. Should it have the Suomi or Glauberyt on it? I have no idea, I am no expert in SMG fame, but many of the recently removed SMGs probably do have a place on the list.  Though, checking with the Assault Rifle article, it can be seen that no "Famous Assault Rifles" list is included, which is probably how it should be done here as well.<BR />—Asatruer 19:23, 29 July 2006 (UTC)
thread_title: "Famous" submachine guns

message: This is starting to bug me. Searching through the images on the US Army website, I came across a picture of a US Soldier using what's apparently called a "PK3" 9mm SMG . This has me interested because I've never heard of a PK3 and this gun does not look familiar to me. However, researching this thing brings me to dead ends, as Wikipedia doesn't have an article on the PK3, and Google searches just bring me back to other US Army pages that host the same picture. I can't seem to find any SMGs that would look like a PK3 when I go through the list of SMGs on the "Submachine gun" Wikipedia page either.
Think anyone would have some info, or at least give a clue to what it could be? SouthernStang93 06:35, 9 December 2006 (UTC)
replies: text: Oops...Cache wasn't loading some images properly, and I must have missed this last night. Someone pointed out that the PK3 is the Polish PM-98, an upgraded version of the PM-84 Glauberyt. I'll still leave this here for future internet reference.

message: Am I right in thinking that submachine guns fire in bursts of about 3 bullets pur trigger pull? If so this should be added. (If I am wrong then sorry & please could someone explain)—Preceding unsigned comment added by 217.43.95.185 (talk • contribs) 
:Fully automatic weapons such as submachine guns fire for as long as the trigger is held down. Skilled shooters can fire single shots from weapons that have full automatic mode only by releasing the trigger quickly. Weapons with built in burst fire usually fire a set number of bullets, I think three is the most common number. --Sus scrofa 19:31, 9 August 2007 (UTC)

message: "Also, SMG's are still widely used by police SWAT teams and other militarized police, because their pistol caliber bullets are less likely to shoot through suspects and walls, causing unintentional injuries to civilians."
There is no citation for this, probably because it isn't true. Pistol cartridge is know for over penetration compared to rifle cartridge because of the shape. The long shape of a rifle round causes the round to slow down immediately when its turns to the side, whereas a more spherical pistol round will not encounter as much resistance.  — Preceding unsigned comment added by 74.137.180.96 (talk) 03:16, 16 July 2016 (UTC)

message: The caption under the MP-40 characterizes it as "iconic", a personal opinion which is of no significance. It was the least produced SMG of ww2 among the major nations (PPSh-41, Sten gun, Thompson). If anything, "iconic" in a ww2 context is the PPSh-41, used in mass up until the second Iraqi war in 2003.

message: Though American troops during the war did call the MP40 the Schmeisser, is it 'popularly' referred to as such? I very rarely see it called that, compared to, 'Tommy Gun', which is a very common term.
It's mentioned that the M3 is "no more effective" than the Thompson, but what are they referring to here? Ballistic performance? An absence of ergonomic improvements? Would be good to elaborate.
