Bad idea. I live in Alaska - a place where you 'might' expect people to actually use a S&W 500 - however about nobody does. My wife and I both carry the 7.5" Ruger Redhawks in 480 Ruger....... the S&W 500 is much more power than that 480. About 2.5 times more. Most decent shooters can keep a 480 in the target black at 25 yards - but after 6-9 factory rounds are ready to put the thing down. I have watched dozens and dozens of new S&W 500 owners at the local Fairbanks, Alaska range. Most all will fire one round - scream, dance, swear - and they do NOT fire a second shout........ and they do NOT hit the target. I have only watched one guy in the past 15 years that could keep a 500 on target - and he was built like a brickhouse. Still, after 18 rounds he was done with that thing. Most all of those 500 new owners were military from the local base - going from a 9mm to the S&W 500 is like going from a motorcycle to a 18 wheeler.
Unless you learn to cast bullets and reload to make light loads - there will be long afternoons at the range for you and your 500. This will be a gun that comes out the safe, you get to show it off - and then it goes back into the safe. My guess, you might fire one or possibly two factory rounds - then you will either quit or make an appointment to see your doctor and have your wrist examined. You could do permanent damage.
The only plus side - perhaps this will be the gun that forces you to learn to reload. You will have a ton of fun firing those big pieces of lead a lot slower - and when they hit the ground you will love how big @ss chunks of earth jump into the sky, even with light loads. Me - I started to reload in 1975 and it has probably saved me $50K to $60K in ammo over the decades. And every year - especially the past decade - ammo has so jumped in price!
I am not sure what is worse. Buying a pistol you cant shoot. Buying a pistol you don't want to shoot. For me, that 500 is both.
