I am hoping to get a lively little discussion going on the virtues of these two pieces for CCW.
The SP101 is smaller and, therefore, more concealable.
The GP100 can handle heavy loads with less recoil; can be fitted with an Millet orange front sight for low visibility; and offers an extra sixth shot. It also has, however, a larger grip and a larger cylinder, which undermines concealability. In a hot climate, it might be difficult to conceal a GP100 under a t-shirt, without printing or dragging.
SP101s are so small that a CCW holder could carry a pair IWB for a "New York reload". That would give him 10 shots. The GP100 is so large that a CCW holder could probably not carry a pair IWB comfortably. That would give him only 6 shots.
Which do you think is the better CCW choice, and why?
