For that kind of money you can buy a S&W 357 and a S&W 9mm and skip the trick cylinder switch. I personally love moon clips and the easy reloads and brass pickup that comes with them.

Wouldn't be so handy a set up if you bumped the yoke latch and found your cylinder laying on the ground when you really really wanted it in the gun.

Gimmicks and guns don't mix that well for me.
