hello cabin4! bluegill festival is coming up! in all fairness, i (like you) have never fired a bfr. from those who have owned them have said they were unsatisfied with the gun. concerning the 45-70, 444, and 45/410; i just cant see how those guns would be viable hunting pistol options. when you look at the size and weight of one of those, you might as well be carrying a rifle. i would love to see how many options a fella would have for holsters (which i have learned before i buy a gun, try to find accessories for it first to see how availible they are). just guessing that a guy wouldnt have very many options. and i guess IF the gun lives up to quality standards, for me it would still come back to packing it. and my raging bull is about as heavy a gun as i want on my side; i think for my purposes, the bfr is about as impractical as it could get. and i think folks would be alot better served with a more viable option.
now as a novelty gun... i would love to fire one. if i had the $ to blow i would buy one just to play. but i dont, and from what i have heard actual owners say about them, i couldnt suggest them.
