'''Rose Hood:''' You're not bad, you're just no good.

Cult bombshells Beverly Garland and Allison Hayes star in this low-budget 1956 panthecolor feminist Western directed by Creator/RogerCorman.

When Marshal Hood of Oracle, Texas, is killed by a hired gunman, his quick-shooting widow, Rose (Garland), straps on his gun and star, puts on some pants, and aims to find out who did the hiring. She has her suspicions about the local saloon owner-slash-madam Erica Page, but doesn't have any proof. Still, Erica becomes worried about Rose interfering with her railroad real estate scheme, and sends for a hired gunman to take care of her.

The gunman, Caine Miro, hits it off with Rose soon after arriving in town, and begins trying to stretch the terms of his contract to avoid killing her. However, he has an old [[UsefulNotes/TheAmericanCivilWar Civil War]] grudge against the town's mayor, and Rose finds her hands full trying to keep the man alive and Cain out of trouble. Can Rose stop Erica's plan? Will Rose redeem Cane before it's too late?

!! ''Gunslinger'' contains examples of the following tropes:
* AbortedArc: The "seeking vengeance on her husband's killers" bit? Gets finished up before she even ''becomes'' a replacement sheriff!
* ActionGirl: Rose.
* AuthorAppeal: Creator/RogerCorman loves strong female protagonists, and regular castmember Beverly Garland continued to fill that role.
* ArtisticLicenseHistory: Caine puts a ''lot'' of importance on the Battle of Lookout Mountain in his vendetta against the mayor, claiming that losing that battle lost the whole war. The actual battle was a relatively minor engagement in 1863, ''two full years'' before the end of the war, and ''after'' the decisive Union victories at Vicksburg and Gettysburg. The engagement didn't even involve the entirety of the armies on both sides, and was fought solely between Hooker's Union XI corps, and three Confederate brigades under Stevenson. Of course, it could more because he lost his brothers there and blames Polk for it, but uses that idea as an excuse.
* BoomHeadshot: How Rose kills Caine. Though...
-->'''Joel:''' ''(as Rose shoots, his hat is knocked off and he slumps over.)'' Ohhh, shot him right in the hat.
* CaptainObvious: Caine, when drunk, tries to woo Erica by saying she has "brown eyes". Nothing significant about them, just "brown eyes".
-->'''Tom:''' ''[as Caine]'' And you got a neck.
* DatingCatwoman: The main storyline between Rose and Caine.
* DeterminedWidow: Rose
* TheExile: Erica's saloon dancers are kicked out of the town after their ambush on Rose fails when Caine rides up.
* FailedASpotCheck: How many people in this film hide in plain sight? At one point, Rose and the Mayor discuss how they've hidden him from Cane at a safehouse, while not noticing him sitting on a horse, spying on them, just a few yards away '''''in the center of the road'''''.
-->'''Joel:''' Apparently they hadn't invented ''peripheral vision'' yet.
** In the beginning of the film, thanks to the poor camera angle, Rose slips into the sheriff's office while two criminals are waiting around the corner!
-->'''Joel:''' Uh, cue the horses!\\
'''Crow:''' ''[Laughs]'' Corman...\\
'''Joel:''' ''[as the criminals ride up to the office]'' Boy, she is slick. How'd she get by us?
* GambitRoulette: Erica's real estate scheme amounts to gambling. She's buying up land in the hopes that a railroad being built through town will make her rich but there's no indication that she has insider knowledge (and if she does, its obviously bad information) and there's no indication that she's trying to sway or fix the results. She's simply betting on a possible outcome.
* HatDamage: Caine's hat is shot off in the final confrontation as he's shot in the head, killing him, though, when shown on ''Series/MysteryScienceTheater3000'', we get this little gem:
-->'''Joel:''' ''[As Caine slumps over dead]'' Ohh, got him right in the hat.
* JobTitle
* TheLoad: Mayor Polk. He talks about how bravely he fought in the war, but when the actual pressure is on, Caine's depiction of him as a stinking coward comes true and he needs Rose, Joshua, or his wife to protect him.
* LoveDodecahedron: Rose, Caine, Erica and Jake. For those keeping score, Rose and Erica love Caine, Caine loves the both of them, Jake loves Erica but Erica will never give him the time of day.
* MurderTheHypotenuse[=/=]YouHaveOutlivedYourUsefulness: When Jake blows up at Erica, Erica sends Caine after him. After a gunfight, Jake is killed and Erica claims self-defense when Rose confronts them.
* NumberTwoForBrains: Jake can never live up to Erica's expectations.
-->'''Jake:''' Want me to do it?\\
'''Erica:''' Do what?\\
'''Jake:''' Kill 'em?\\
'''Erica:''' No, Jake, you're too stupid.[[note]]To be fair, she's saying the ''suggestion'' is stupid, because Jake is well-known as her assistant and would make Erica the prime suspect.[[/note]]
* ReformedButNotTamed: Caine thinks of himself as this. [[spoiler: He's not reformed either.]]
* ReplacementLoveInterest: How long is Marshall Hood dead before Caine comes along? A month?
* StuffedInTheFridge: Rose's husband is dead before the opening credits roll, and he only seemed to exist to motivate Rose to seek vengeance against his killers.
* TooDumbToLive: Mayor Polk.
* TroubledButCute: Caine.
* ZanyScheme: The Mayor sees Erica's plot (buying up all the land in town in hopes that a new railroad will make property values skyrocket) as this. Particularly since it's not even guaranteed that the new railroad will run through Oracle. [[spoiler:It won't.]]
