The GP-100 is a great gun but it's also a heavy tank of a gun.
It's built like an anvil. That's a good thing for me but it might be a bad thing for some (weight).
For my own uses, I absolutely love the 3" SP-101. It's as close to a "do-all" handgun as I can imagine. But it does have fixed sights. So far, that hasn't really made much difference though - After I got the sights adjusted they seem to put just about every round I've tried to the same POI regardless of what weight it is or how fast it's going.
