The Bulldog FSN21 Extreme OWB nylon holster is a straightforward, hardworking choice for Ruger Mark pistols with 5–6.87" barrels. Built for shooters who want a reliable outside-the-waistband rig without overcomplication, this ambidextrous holster pairs serious durability with practical comfort—the kind of gear that performs whether you're at the range, in the field, or carrying daily.
Construction matters in a holster, and Bulldog designed the FSN21 with a water-resistant outer nylon shell backed by top-grade fused padding to protect both gun and shooter. The soft, scratch-resistant inner lining keeps your pistol's finish unmarked, and a built-in spine protector runs along the back—a thoughtful detail that shields your gun's sights from snagging or tearing the lining. That kind of attention extends to retention and fit: the holster is molded specifically for Mark-series pistols in the 5–6.87" barrel range, so you get a secure seat every time.
The ambidextrous belt loop and metal clip design means you can carry strong-side or cross-body, right- or left-handed, without buying a second holster. Adjustment is honest and direct—no gimmicks, just proven materials and a form factor that works. If you shoot a Ruger Mark and value a no-fuss, durable OWB holster that protects your investment and stays put, the FSN21 Extreme is worth a serious look.
