Ruger SP101 KSP-321 .357 Magnum 2.25-Inch Stainless Revolver, 1995 Production with Crimson Trace Lasergrip
This 1995 Ruger SP101 KSP-321 is a compact, 5-shot .357 Magnum revolver built on Ruger’s one-piece stainless frame. A factory-pinned 2.25-inch barrel, triple-locking cylinder, and transfer-bar safety give it strength well beyond its size. The revolver wears a Crimson Trace rubber lasergrip for enhanced ergonomics and point-ability, making it a notable example of a durable, concealment-ready wheelgun from the mid-1990s.

What’s Included
- Crimson Trace rubber lasergrip (installed)
Produced in 1995 (serial prefix 571-), this SP101 represents the early era of Ruger’s compact magnum revolvers. The KSP-321 designation indicates a satin stainless finish, 2.25-inch barrel, and full underlug—features valued for their balance of strength and concealability.
The revolver’s one-piece frame lacks side plates, eliminating a common flex point found on other designs. Combined with Ruger’s triple-locking cylinder that secures at the front, rear, and bottom, the SP101 is engineered to handle full-power .357 Magnum as well as .38 Special +P ammunition with confidence.
A pinned serrated ramp front sight paired with an integral rear notch offers a snag-free profile for daily carry. The external spur hammer supports both double-action and single-action fire, giving the shooter flexibility for different scenarios.
The factory satin stainless finish resists corrosion and simplifies maintenance, while the compact five-shot cylinder keeps the profile slim. Even with its stout construction, the 2.25-inch barrel keeps overall length minimal for waistband or ankle carry.
The Crimson Trace lasergrip, though currently non-functional, adds a tactile rubber surface and an extended grip profile that helps manage recoil without increasing bulk.
