shooter1, you've figured out why lowering a hammer on a 1911 with beavertail is a pain. On the 1911-A1 pattern guns, the grip safety is so short that it doesn't get in the way of the thumb's movement toward the hammer spur. This is the one handed version, which I don't use. With two hands, things are more stable for me (that is, use your strong hand to hold the gun as if you were going to shoot and use the thumb of the weak hand to lower the hammer). The grip safety is also short enough to allow the thumb to pass around the back of it to cock the hammer on a condition 2 draw. Cocking on the draw is instinctive if you've done it enough with revolvers, and if you're already as slow on the draw as I am it won't slow you down any more.
In getting to condition 2, you must depress the trigger fully until the half cock notch is past the sear, otherwise you're either at half cock or have dinged your sear.
