I can't say I enjoy the external safety personally. I don't like the double action pull for the first shot. (Meaning, drawing from holster, taking off safe, and firing. The way the Army deems the proper way.) I like the Sig decocker personally a lot more than the external thumb safety that the Beretta's have. Being in SUV's almost 90% of the time, I was always finger fucking my M9 to see what position that damn safety was in. Most of the time I was red with the safety off (Round in the chamber for civilians) which made it a point and draw weapon. Taking the weapon off safe after the draw, breaks your grip even for just a split second. But, I borrow my dad's 92F if I want to get a little brush up on the M9 style pistol. I put a set of hogue grips on mine, and it made a world of difference to me.
