Just wandering if anyone has had the opportunity to shoot the .50 caliber handgun by S&W, called the S&W 500? I have read articles that the 4 inch version can be easier to handle than the 8.5 inch version. It's a big gun with pricey ammunition, but control seems to be reasonable despite the power of ammunition. Also, interesting that Oklahoma will not let anyone carry larger than .45 caliber. Other states are free of this limitation. Any thoughts?
