About
What it is, and why it matters
The Cimarron Model P Jr is a single-action revolver chambered in .38 Special, a roughly three-quarter-scale reproduction of the Colt Single Action Army pattern distributed in the United States by Cimarron Firearms and built in Italy by Uberti. Where the full-size Model P retains a standard grip frame, the Junior shrinks the frame, cylinder and barrel around smaller cartridges, producing a lighter, trimmer sixgun well suited to the .38 Special. The traditional single-action lockwork requires the shooter to manually cock the hammer for each shot, feeding from a six-round fluted cylinder loaded one round at a time through a hinged loading gate and cleared with a spring-loaded ejector rod. The pre-war-style color case-hardened frame, hammer and loading gate contrast with the polished blued barrel, cylinder and ejector housing, and smooth walnut grip panels wear Cimarron medallions on both sides. Fixed 19th-century-style sights, a rounded blade front paired with a rear groove, complete the period-correct presentation. Offered with 3.5-inch, 4.75-inch and 5.5-inch barrels, the Model P Jr appeals to cowboy-action shooters, collectors and recreational plinkers who want authentic frontier styling in a more compact, comfortably shootable package.
Cimarron Firearms built its reputation on historically faithful reproductions of Old West firearms, and the Model P Jr scales down the iconic Single Action Army silhouette for shooters who find the full-size Colt pattern too large. Chambered for gentle, plentiful cartridges like the .38 Special, it has become a favorite for cowboy-action competition and casual range use.
Approximately three-quarter-scale Colt SAA-pattern revolver. Made by Uberti (Italy), distributed by Cimarron Firearms. Also offered in .22 LR/.22 WMR and .32-20/.32 H&R Magnum convertible chamberings. No transfer-bar safety; uses traditional single-action lockwork.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
