If you’re searching for “BFR .45LC/.410 6-shot,” “handgun that shoots .410 and .45 Long Colt,” or “vent-rib BFR 7.5 inch stainless,” this page addresses the buyer questions and practical notes you need.

Overview

The BFR family is engineered as a magnum platform from the ground up: machined, stress-relieved, cut-rifled barrels, beefy stainless frames, and single-action lockup designed for repeatable accuracy and longevity. The .45LC/.410 long-cylinder model uses a 7.5″ cut-rifled barrel to deliver solid handgun ballistics with .45 Long Colt loads while offering .410 slug/shot capability where the chambering supports 2½” or 3″ shells. The vent rib reduces barrel glare and produces a consistent sight plane for faster target acquisition in the field.

Key features & buyer benefits

• Dual-role chambering: .45 Long Colt primary with the option to accept .410 shotshells (verify 2½” vs 3″ compatibility for the specific model).
• 6-Shot cylinder: Increased capacity for extended outings and greater flexibility in the field.
• 7.5″ cut-rifled barrel with vent rib: Match-style rifling for accurate bullet performance and a vented rib to improve sight acquisition and reduce glare.
• Stainless construction: Brushed stainless finish for corrosion resistance and long service life in harsh field environments.
• Included choke & wrench: Modified choke and wrench supplied for the .45LC/.410 configuration to support slug and shotshell use.
• Ergonomics & sights: Rubber or optional grip panels, factory fixed front and rear adjustable sights for quick alignment and field zeroing.
• Field versatility: Useful for brush-country hunting, camp defense, small game with .410, and heavy-hitting .45LC performance in one platform.

Practical shooting & load guidance

• Confirm your revolver’s .410 chamber length (2½” or 3″) before using 3″ shells. Only use shotshell lengths the cylinder is specifically chambered for.
• Use reputable factory .45 Long Colt loads or handgun-appropriate .410 slugs/shot loads. Test multiple loads to determine point-of-impact, feeding, and accuracy in your revolver.
• The vent rib helps maintain a consistent sight plane and reduces reflective glare for faster acquisition of moving targets—useful in hunting and close-in work.
• Expect substantial recoil with stout .45 Long Colt loads and energetic .410 slugs; train with progressively heavier loads to build comfort and follow-up speed safely.

Maintenance & care

• After firing shotshells, clean the forcing cone, chamber throats and bore thoroughly to remove wad and shot residues—use brushes and solvents sized for .45/.410 diameters.
• Inspect the modified choke threads and wrench regularly and keep choke threads lightly oiled during storage to avoid corrosion or seizing.
• Check extractor, crane/yoke, and cylinder throat condition periodically, especially after heavy use with powerful loads; consult a qualified gunsmith for any concerns.
• Store the revolver in a dry environment and re-check sights and any fitted accessories after shooting to maintain reliability and zero.

Buyer FAQs

• Q: Will this shoot 3″ .410 shells?
  A: Some .45LC/.410 BFR models accept 3″ shells, others are limited to 2½”. Always verify the specific model’s chamber length before using 3″ shotshells.

  A: BFR configurations can vary; this listing describes a 6-shot configuration — confirm with your dealer that the specific SKU ships as 6-shot prior to purchase.
• Q: Does the revolver ship with a scope mount?
  A: Unlike most BFR models, many .45LC/.410 long-cylinder variants are shipped without the MRI Weaver-style scope mount. If you plan to use optics, ask your dealer about mounting options or gunsmith installation.
• Q: Can I use heavy rifle-grade .45LC loads?
  A: Do not use rifle-pressure or non-handgun published loads. Use reputable factory handgun loads or established handgun reloading data; improper ammunition can be unsafe and may void warranties.

Safety & legal reminders

Always follow firearm safety fundamentals: treat every firearm as loaded, keep the muzzle pointed in a safe direction, keep your finger off the trigger until ready to fire, and be certain of your target and what lies beyond. Because this model can accept both .45 Long Colt and .410 shotshells, always confirm the correct ammunition for your particular cylinder/choke setup. Verify federal, state, and local laws regarding ownership, transport, hunting seasons, and shotshell legality before purchase or use. If shipping is required, confirm FFL/transfer requirements with your dealer.
