4D4's right. Keith lobbied to make the 41mag the standard police round. More power than a 357mag, easier to handle than a 44mag. I have both, (Ruger Redhawk, S&W Model 29), and like them fine. The 41's a lot more well mannered than the 44. The 44's recoil is severe and second shot acquisition is problematic, even for an experienced shooter. That said, it's extremely accurate and fun to shoot, as is the 41. The down side, unless you load your own, both are expensive to shoot and 41mag ammo can be hard to find.
