I don't own one (yet) but I have shot and admired them. If I see a 5" 945 for sale at store or show locally I will likely buy it.
However, it is NOT a 1911. The trigger, thumb safety and grip safety are 1911 parts. NOTHING else will interchange; not even magazines, it is a natural 8-shot. It is a bit heavier than a 1911 and the grip shape and angle are enough different to tell. It is a S&W, not a Colt clone. If you want a real 1911 for the same or a bit more money, look Wilson, Baer, or Rock River. If you want a S&W with the safety in the right place, I think the 945 is a good gun.
