Ruger SP101 (9mm, 5-Shot)

The Ruger SP101 is a series of small-frame, double-action/single-action revolvers known for their robust construction and durability. They are built to handle a steady diet of full-power ammunition and are often noted for their manageable recoil, thanks to their solid stainless steel frame and full-length ejector rod housing.

Key Features of this Model

  • Caliber: 9mm Luger (9x19mm Parabellum). This is a less common caliber for the SP101, which usually comes in .357 Magnum or .38 Special. A 9mm revolver offers the advantage of ammo commonality if the user also owns a 9mm semi-automatic pistol, and the use of readily available and often less expensive ammunition.

  • Capacity: 5-Shot. Standard capacity for the small-frame SP101.

  • Action: Double-Action/Single-Action (DA/SA).

    • Double Action: Pulling the trigger cocks and releases the hammer, providing a faster but heavier pull.

    • Single Action: Manually cocking the hammer first results in a much lighter and crisper trigger pull for more precise shooting.

  • Construction: Stainless Steel. This provides excellent corrosion resistance and strength.

  • Grips: This particular model appears to have an aftermarket or factory rubber grip with finger grooves, which typically offers superior recoil absorption and a more comfortable, secure hold than the standard small-profile grips.

  • Moon Clips: The 9mm version of the SP101 requires the use of moon clips (partial or full) to hold the rimless 9mm cartridges for loading and, most importantly, for ejection.
