===Locks===
There are several types of locks that serve to make it difficult to discharge a firearm. Locks are considered less effective than keeping firearms in a safe since locks typically do not prevent the removal or theft of the firearm, after which the handler can bypass the lock at their leisure.<ref name="safsell"/>  Some manufacturers, such as [[Taurus (manufacturer)|Taurus]], build locks into the firearm itself.

Some jurisidictions such as the US state of California require that locks be tested by a laboratory and receive approval for sale.<ref>{{cite web| title = Aroner-Scott-Hayden Firearms Safety Act of 1999| url = http://caag.state.ca.us/firearms/dwcl/12087.htm| publisher = State of California| year = 1999| access-date = 18 May 2009| archive-url = https://web.archive.org/web/20090704130907/http://caag.state.ca.us/firearms/dwcl/12087.htm| archive-date = 4 July 2009| url-status = dead}}</ref><ref>{{cite web| title = Pro-Lok: Professional Quality Tools - CADOJ REGULATIONS | url = http://www.gunlockinfo.com/s-53-cadoj-regulations.aspx| publisher = PRO-LOK| date = 2007–2009| access-date = 18 May 2009|archiveurl=https://web.archive.org/web/20110711133548/http://www.gunlockinfo.com/s-53-cadoj-regulations.aspx|archive-date=11 July 2011}}</ref>

There is controversy surrounding manufacturing standards, usage, and legislation of trigger locks. Supporters argue that they protect children by preventing accidents, whilst critics note some models have been shown to be easily removed by children with very little force and common household tools. Additionally, many firearms can discharge when dropped without operating the trigger. Trigger locks are not designed for use on loaded firearms as the locking mechanism itself may foul or manipulate the trigger if pressure is exerted on the lock or during installation/removal; critics argue that this may make the firearm more dangerous by creating the illusion of safety.<ref>{{Cite web |last=Peters |first=Justin |date=18 July 2013 |title=Trigger Locks, the Dubiously Effective Safety Measure That Gun Control Advocates Love |url=https://slate.com/news-and-politics/2013/07/trigger-locks-the-dubiously-effective-safety-measure-that-gun-control-advocates-love.html |access-date=22 May 2022 |website=Slate Magazine |language=en|archiveurl=https://web.archive.org/web/20230530201147/https://slate.com/news-and-politics/2013/07/trigger-locks-the-dubiously-effective-safety-measure-that-gun-control-advocates-love.html|archive-date=30 May 2023}}</ref> A former senior product manager at [[Master Lock]] was quoted as saying ''"If it is a loaded gun, there isn't a lock out there that will keep it from being fired...

====Chamber & cable locks====

Chamber locks aim to block [[ammunition]] from being chambered, since most firearms typically cannot be discharged unless the ammunition is in the correct position. They are used to prevent live ammunition from being loaded into a firearm by blocking the chamber with a [[dummy cartridge]] or a chamber plug.<ref name="sport-lockpick"/>  Another type is one in which a steel rod locked into the safety cartridge with a key.  As long as the rod and safety cartridge are engaged, the [[dummy round]] cannot eject nor can live ammunition be loaded into the firearm.  Chamber locks work with most firearm types including [[revolver]]s, [[pistol]]s, [[rifle]]s and [[shotgun]]s.  They are available in any [[caliber]] and length, and may include such features as unique keying, rapid removal.

Cable locks usually thread through the [[receiver (firearms)|receiver]] via the ejection port and magazine well of repeating firearms.<ref name="sport-lockpick"/>  These locks physically obstruct the movements of the [[bolt (firearms)|bolt]], and also prevent a [[magazine (firearms)|magazine]] from being inserted on magazine-fed firearms. preventing the cycling of the [[firearm action|action]].<ref name="sport-lockpick"/>
