The Ruger Blackhawk Convertible is a single-action revolver chambered in .357 Magnum with an included 9mm Luger cylinder, allowing the owner to switch between both cartridges. The 6.5-inch cold hammer-forged stainless steel barrel provides good sight radius and velocity for both calibers. At 48 oz, it is a full-size, heavy-framed revolver with the rosewood (Altamont hardwood) grip contributing to recoil absorption during extended .357 firing.

Detailed Features 

The convertible feature means two separate cylinders ship with the revolver: one for .357 Magnum (which also fires .38 Special), and one for 9mm Luger. Switching cylinders is straightforward and takes under a minute. This makes the Blackhawk Convertible practical if you already have 9mm on hand or want to reduce per-round costs during range sessions. 
 
The adjustable rear sight and ramp front sight allow windage and elevation correction for different loads and distances. The stainless steel finish handles weather and outdoor use well without requiring the same maintenance level as blued steel. The single-action mechanism requires cocking the hammer before each shot, which produces a light, consistent trigger pull. 
 

Usage Scenarios 

The 6.5-inch barrel and .357 Magnum power are well suited for hunting medium game at handgun ranges. At the range, the adjustable sights and single-action trigger make deliberate target shooting straightforward. The 9mm cylinder extends utility to high-volume practice with more widely available ammunition.

The Blackhawk Convertible in .357/9mm gets positive feedback for its dual-cylinder versatility. Owners appreciate the ability to practice with 9mm and switch to .357 Magnum when needed, which is a practical cost management tool for range use. The stainless steel construction is consistently praised for durability and low maintenance.

Recoil management with .357 Magnum loads is noted as manageable given the 48 oz frame weight and rosewood grip. The single-action trigger pull gets favorable mentions for consistency and lightness compared to double-action revolvers at similar prices.

Critical feedback centers on weight — at 3 lbs, it is not a carry revolver for most shooters — and on the single-action requirement, which some find slower than double-action alternatives in time-sensitive scenarios. The 9mm cylinder occasionally prompts questions about headspace and reliability with moon clips vs. moonclip-free loading; most owners find it reliable once they understand proper cylinder seating technique. Overall sentiment is positive, particularly among hunters and traditional revolver enthusiasts.
