High capacity .45s are just too big and most of us want more than 7-8 rounds. That's where my affinity for the .40 S&W comes in. A slew of big bore slugs which would fit into a 9mm gun. That was genius!
hi-cap 9's and .40's have the same bloat problem.
And .40 is also a worst-of-both-worlds solution. It's a high-pressure round in a small case with no room for error, so it has the nasty snap & crack of the 9mm, without the full diameter of the .45. If I WANTED a .40 (ballistics are excellent), I'd probably get one in a single-stack platform anyway.
All of this has reminded me of a revolver which came out quite a few years ago. it was made in Conroe, Texas IIRC and could chamber and fire almost anything in the 9mm/.38 size. It used a strange spring loaded extractor system. The idea being you could shoot .38 specials in the US and 9mm in other parts. Cool idea, but I don't know what became of it. Maybe it was called "Medusa"? Anyway, it was neat. Take care.
Ah yes, I recall that one.
Too bad 9mm (.355") bullets shoot like crap in a .357 bore.
I like a strong, modern, single-action .45 revolver for this reason: swap out the Colt cylinder for a .45acp. That way you can get modern factory ammo, cheap or fancy, and handload whatever you want in .45Colt cases up to .44mag energy levels with less chamber pressure.
Back towards the original topic, one thing the .500 does offer as a revolver (and there are SO MANY big bore revolver choices) is handloading versatility. You can lob 750fps softballs with huge slugs or monsters at supersonic speeds if you can handle it. I'd take up bullet casting if I had one of these.
Personally I prefer subsonic handgun ammo. 158-180gr in .357 cases at 1000fps is my fav - huh, kinda sounds like 180gr .40 numbers but with better downrange ballistics...
If you're gonna restrict your velocity to subsonics, it makes sense to boost diameter, so .41mag, .45Colt, .454 and the exotics like .475 Linebaugh, .480 Ruger, .500 Linebaugh etc. start to make sense. But the .460 S&W and full-power .500's don't appeal to me. Chasing velocity in a handgun is a literal headache. I can't justify an iron-sighted handgun shot past 100yds (even that far is a stretch), so why blast myself to oblivion on the operator-end to do a rifle's job? And of all of those, the only one that easily swaps for affordable factory ammo (defensive ammo too) is the .45acp/.Colt/.454.
