Hold on
I bought my S&W 500 the week they were released. I started looking for a speed loader the same day I got my pistol home, and gave up until this morning when I happened to see a post to 5 Star Firearms. I didn't buy my S&W 500 for any practical reason, but more for a show piece.
I have fired my S&W 500 many times, and some of the production shells I’ve run through it have burned hair off my arms. I have managed to empty the cylinder as fast as I can pull the trigger, but the experience is quite brutal one handed. I stand 6’ 3” and dress out at 205 pounds, and I’m a United States Marine Nam Era Veteran who is accustomed to big guns.
I actually bought these speed loaders as a novelty paper weight, but will get another set for several other revolvers I own. If you ever happened to use the S&W 500 Magnum in a defense situation, even if you miss, your target would probably be vaporized by muzzle blast. I can’t imagine needing a speed loader for a second set of shots out of the 500, but their fun just for havin!
