The Magnum Research BFR (Big Frame Revolver) is a single-action revolver chambered in .45 Colt that also accepts .410 gauge shotshells. The 7.5-inch stainless steel barrel has a 1:20 twist rate and a brushed finish that handles outdoor exposure without corrosion concerns. Capacity is 6 rounds. Total weight is 4.5 lbs, which is substantial for a revolver but helps manage the recoil from .45 Colt loads. Trigger pull runs 3 to 4 lbs.

Features 

The dual-caliber capability is the BFR's defining feature. .45 Long Colt handles most shooting tasks, and the ability to chamber .410 shotshells adds utility for small game or snake defense in the field. Factory black fixed front sight and adjustable rear sight let you tune for elevation and windage without aftermarket work. The stainless finish and robust frame construction are built to hold up in hunting conditions where revolvers take real abuse.

The Magnum Research BFR in .45 Colt/.410 with the 7.5-inch barrel draws a consistent split in owner feedback between appreciation for its capabilities and honest acknowledgment of its size.

The dual-caliber setup gets genuine credit. Owners who carry it in the field for small game or as a backup during hunting trips find the .410 option practically useful, not just a novelty. Build quality draws consistent praise — the stainless construction and overall fit feel solid for the money. Accuracy in single-action mode with .45 Colt gets positive marks at reasonable distances.

The weight and size are the main friction points. At 4.5 lbs with a 7.5-inch barrel, this is a large revolver to carry all day, and it generates real debate among owners about whether the heft is worth the capability. Recoil with .45 Colt is manageable for most; .410 shells in a revolver frame is a different experience that not everyone finds enjoyable.

Price relative to other big-bore revolvers comes up in discussions. Some owners feel it's justified by the dual-caliber design and build quality; others think comparable revolvers offer more for less. Aftermarket accessory options are a frequent discussion topic among owners who want to customize.
