== Development ==

In 1963, [[Elmer Keith]] and [[Bill Jordan (Marine)|Bill Jordan]], with some help from [[Skeeter Skelton]], petitioned [[Smith & Wesson]], Remington, and [[Norma Precision|Norma]] to produce a [[pistol]] and [[ammunition]] in .41 caliber which would fall between the extant [[.357 Magnum]] and [[.44 Magnum]] cartridges in [[External ballistics|ballistic performance]], and at the same time address perceived shortcomings with those loads.{{Cn|date=March 2025}} While as early as 1955 Keith had suggested a new, medium-powered "[[.41 Special]]" cartridge, this idea was passed over in favor of the higher-powered "Magnum" option, and the Special survives only as a custom [[wildcat cartridge]], bearing roughly the same relation to the .41 Magnum as the [[.38 Special]] does to the .357 Magnum and as the [[.44 Special]] does to the .44 Magnum.<ref name="Ready"> {{cite journal | last = Pearce | first = Lane | journal = [[Shooting Times]] | date = April 7, 2011 | title = Ready For The .41 Special? | url = http://www.shootingtimes.com/ammo/ammunition_ready_for_the_41_special_040711/ }} </ref>

The .357 Magnum suffered from restricted [[Terminal ballistics|terminal ballistic]] effectiveness in the early 1960s, as [[Hollow point bullet|jacketed hollow point]] bullets were not yet commonly available, and the [[Manufacturing|manufacturers']] standard loadings consisted of simple [[Bullet#Materials|lead]] [[bullet]]s. The powerful .44 Magnum, primarily a heavy hunting round, was considered overkill for [[police]] use, generating too much [[recoil]] for control under rapid fire. In addition, the revolvers chambered for the .44 Magnum were considered too large, bulky, and heavy for police to carry.<ref name="doover">Smith, Clint. [http://findarticles.com/p/articles/mi_m0BQY/is_4_51/ai_n11840297 "The .41 Mag: If only we could do it over"], ''Guns'' magazine April 2005. BNET Web site. Accessed August 6, 2008.</ref>

Keith's original vision called for dual power levels in the .41, a heavy magnum load pushing a {{convert|210|gr|g|sing=on}} [[Jacketed hollow point|JHP]] at a [[muzzle velocity]] of {{convert|1,300|–|1,400|ft/s|m/s|abbr=on}}, and a milder police loading which was to send a {{convert|200|gr|g|sing=on}} [[semiwadcutter]] downrange at around {{convert|900|ft/s|m/s|abbr=on}}.<ref name="doover" />

These plans went awry due to an ongoing fascination in the firearms community with high-powered cartridges; Remington was swayed by this community's influence and instead of following Keith's [[blueprint]], chose to emphasize the performance of the new cartridge. As a result, the .41 "Magnum" load was released at an advertised {{convert|1,500|ft/s|m/s|abbr=on}}, and even the "light" police loading was introduced with a {{convert|210|gr|g|abbr=on}} lead semiwadcutter "warmed up" to about {{convert|1,150|ft/s|m/s|abbr=on}}. However, the police load as delivered was regarded as overpowered by most [[Law enforcement agency|law enforcement agencies]], many of which were still using .38 Special revolvers.<ref name="doover" />

Additionally, Smith & Wesson had simply adapted their large N-frame revolvers for the new cartridge, which did not address size and weight concerns.<ref>Taffin, John. [http://findarticles.com/p/articles/mi_m0BTT/is_166_27/ai_109264984 "The .41 Magnum Turns 40 - The Sixgunner"] {{Webarchive|url=https://web.archive.org/web/20100327225455/http://findarticles.com/p/articles/mi_m0BTT/is_166_27/ai_109264984/ |date=2010-03-27 }} ''American Handgunner'' magazine, Nov-Dec 2003. BNET Web site. Accessed August 6, 2008.</ref> The [[Smith & Wesson Model 57#Smith .26 Wesson Model 58|Model 58]], targeted for the law enforcement [[Market (economics)|market]], was introduced on July 10, 1964. Weighing {{convert|41|oz|g|abbr=on}}, the Model 58 compared unfavorably with other revolvers available at the time, such as Smith's own {{convert|34|oz|g|abbr=on}} [[Smith & Wesson Model 10|Model 10]] in .38 Special.{{Cn|date=March 2025}}

These combined factors mostly eliminated the .41 Magnum from consideration for its intended market as a law enforcement firearm, although it continued to be touted as such and was adopted by a few law enforcement agencies.<ref name="doover" />

For a handgun cartridge, the [[bolt thrust]] is considerable at [[C.I.P.]] conform maximum loads and an important factor in weapons design. The greater the bolt thrust, the stronger the locking mechanism has to be to withstand it. Smith & Wesson produced a high-end, premium revolver in .41 Magnum, the [[Smith & Wesson Model 57|Model 57]], identical to the .44 Magnum-chambered [[Smith & Wesson Model 29|Model 29]].{{Cn|date=March 2025}} [[Magnum Research]]'s [[Desert Eagle]] division produced a .41 Magnum in their semi-automatic Mark VII. Sturm Ruger also produced their [[Ruger Blackhawk|Blackhawk]] single-action revolver in .41 Magnum.{{Cn|date=March 2025}}

A couple of manufacturers have produced lever-action rifles chambered in .41 Magnum. [[Marlin Firearms|Marlin]] produced four variants of its [[Marlin Model 1894|Model 1894]], but no longer offers any model chambered for it. [[Henry Repeating Arms]] introduced a .41 Magnum variant of their Big Boy Steel model in 2016.<ref name="Henry">{{cite journal | last = Alberts | first = Kristin | journal = Guns | date = July 27, 2016 | title = Gun Review: Henry adds .41 Magnum to Big Boy Steel Lineup | url = https://www.guns.com/news/review/gun-review-henry-adds-41-magnum-to-big-boy-steel-lineup-video}}</ref>

== Market reception == The .41 Magnum never enjoyed the popularity and success of either the .357 Magnum or .44 Magnum cartridges, but is still prized by [[Handgun hunting|handgun hunters]] as some feel it generates somewhat lighter recoil and slightly flatter bullet [[trajectory]] at long range than the .44 Magnum.<ref>[http://www.notpurfect.com/main/m57.htm "S&W Model 57"], Notpurfect Web site. Accessed August 5, 2008.</ref> Nevertheless, the .44 Magnum still catalogs a greater variety of heavier bullet weight offerings which are more effective on larger game, and boast a slight edge in power when using the heaviest [[factory]] loads, or if pushed to the edge by handloading (heavier bullets or bullets of different types).<ref>[http://pdf.textfiles.com/manuals/FIREARMS/vihtavouri.pdf VihtaVuori Reloading Guide, 2002]</ref> Marshall and Sanow called the .41 Magnum "one of our most unappreciated calibers".<ref>{{cite book|title=Street Stoppers|first= Evan|last= Marshall |author2=E.
