A '''flare gun''', also known as a '''Very pistol (sometimes spelled Verey)''' or '''signal pistol''', is a large-bore handgun that discharges flares, blanks and smoke. Today, a flare gun is typically used to produce a distress signal.

== Types == The most common type of flare gun is a Very (sometimes spelled Verey),<ref>{{cite book|title=Chambers 21st Century Dictionary (revised ed.)|url=https://books.google.com/books?id=D37Cd3Ad7eIC&pg=PA1578|year=2005|publisher=Allied Publishers (P) Ltd.|location=New Delhi|isbn=81-86062-26-2|page=1578}}</ref> which was named after Edward Wilson Very (1847–1910), an American naval officer who developed and popularized a single-shot breech-loading snub-nosed pistol that fired flares ("Very lights").<ref>{{Cite book |url=https://books.google.com/books?id=n3DxAAAAMAAJ&q=%22Edward+W.+Very%22 |title=Pyrotechnics: from the viewpoint of solid state chemistry |last=McLain |first=Joseph Howard |publisher=Franklin Institute Press |isbn=9780891680321 |page=87 |year=1980 |access-date=4 January 2018 |via=Google Books |quote=Another historically famous flare, still in use, is the ''Very'' light, invented by a U.S. naval officer, Edward W.

Flare guns may be used whenever someone needs to send a distress signal. The flares must be shot directly above, making the signal visible for a longer period of time and revealing the position of whoever is in need of assistance. There are four distinct flare calibers: 12-gauge (18.53&nbsp;mm), 25&nbsp;mm, 26.5&nbsp;mm, and 37&nbsp;mm{{spnd}}the first three being the most popular for boaters.<ref name="Firearms News" />

=== Pocket mortars === In World War II, Germany manufactured grenades designed to be fired from adapted flare guns known as the Sturmpistole in its final form. Fragmentation rounds and anti-tank HEAT warheads were produced for the pistol, however the latter only had 80&nbsp;mm of penetration (RHA) requiring it to be either fired on lightly armoured targets or used on the sides and rears of heavily armoured targets such as the late-war tanks that were beginning to enter service.<ref>{{Cite web |url=https://www.armymuseum.co.nz/kampfpistole/ | title=Kampfpistole | date=16 June 2023 |access-date=2023-10-21 | archive-url=https://web.archive.org/web/20231021222609/https://www.armymuseum.co.nz/kampfpistole/ | archive-date=2023-10-21}}</ref>

The Soviets developed the Baranov pocket mortar during 1943, which fired a 175&nbsp;g round with an 8&nbsp;g explosive charge out to a range of 200-350&nbsp;m (it was also proposed to increase this to 600-700&nbsp;m).<ref>{{cite web | url=https://www.tankarchives.ca/2018/07/personal-artillery-for-downed-pilot.html | title=Personal Artillery for a Downed Pilot }}</ref> A later development was the PSA/PSA-1/ASP, a copy of the US issue M8 flare pistol. This fired an experimental grenade which was 40% more powerful than that used with the Kampfpistole.<ref>{{cite web |title=Secret Army Projects |url=https://www.secretprojects.co.uk/threads/firearms-secret-projects.3265/page-3 |website=Secret Projects |access-date=25 July 2025}}</ref><ref>{{cite news |last1=William |first1=Chris |title=They lit up the night: Military “Very Pistols” |url=https://www.militarytrader.com/militaria-collectibles/very-pistols-illuminated |access-date=25 July 2025 |work=Military Traders |publisher=© Active Interest Media |date=21 June 2019}}</ref>

=== Conversion kits === Conversion kits are available intended to convert flare guns to accept conventional ammunition by use of barrel inserts. There are also 12 gauge inserts intended to allow use of rifle or pistol ammunition in conventional 12 gauge shotguns. Use of any of these devices in the Orion plastic 12 gauge flare gun is not recommended by the manufacturer and ATF tests have demonstrated that sometimes a single use results in a catastrophic failure. In the United States, if these conversion kits are used in a metal flare gun, the converted gun is considered to be a firearm by the ATF. If a rifled barrel insert is used, the converted firearm is classified as a pistol; if a smoothbore barrel insert is used, the converted firearm is classified as an AOW subject to the additional requirements of the NFA.<ref>[https://www.atf.gov/firearms/docs/open-letter/national-may2006-open-letter-flare-inserts-any-other-weapon/download "Flare Insert – Any Other Weapon"] {{Webarchive|url=https://web.archive.org/web/20170427215028/https://www.atf.gov/firearms/docs/open-letter/national-may2006-open-letter-flare-inserts-any-other-weapon/download |date=2017-04-27 }}, ATF Firearms Technology Branch, May 4, 2006.</ref> Flare cartridges are low pressure compared to conventional ammunition and even metal flare guns are not designed or intended to be used with conventional ammunition. Conversion of a flare gun to fire conventional ammunition may also be restricted by local improvised firearm laws.
