Help me find this cowgirl movie
 

I saw it "once upon a time", so I barely remember anything, but I DO remember a KEY momentum:

the heroin had on her saddle some golden-coloured granades what she could fire from her pistol (attached to the end of the tube fired instead of the usual bullets from the barel). Of course this happened only at key moments as she had limited source (maybe even purposefully, as westerns usually have vendetta as motivation against a group of bandits).

I ask this here too just in case:ouch:


Got the answer! It was "crazy westerners"
