.44 Mag is overrated as a PD handgun caliber. It's okay for PD as long as it's a reduced charge and payload. One of my fav loads is 240 gr hard cast lead SWC at 1000 FPS. Ithits hard and is accurate too. Slow fire, .44 Mag can be very accurate and carry a lot of energy (relative to handguns) at 100 yds, but that's hardly a PD shot. But most guys with a .44 magnum want to shoot 240 gr at 1250-1400 FPS because a .44 Magnum is all about power IMO those loads are brutal to the shooter.

But like I stated, IMO .44 Mag is overrated. I went back to 9mm in a Glock G-19 for carry. The newer 147 gr loadings have plenty of penetration and the Gold Dot opens up nicely. That and it groups well for me with relatively mild recoil. YMMV, lotsa different valid opinions. $.02
