You know what would be perfect? A Leupold 3.5-10x40 Tactical, but since the money is an issue you could go with the new VXII Leupold 3-9x40 Mil-Dot for $389.95. It has target knobs, mil-dot reticle (that you will need to get accustomed to) and multi-coatings.
The SS is also a good idea, it would be better for police training as it is a fixed power with exposed target knobs and a mil-dot. It is more of just a tactical scope, where the Leupold is more of a hunting/tactical scope with its variable magnification. I would not consider the Elite 10x right now as we have been getting a pretty high rate of returns on them with the complaint being that they will not hold zero.
I would go with standard Leupold rings and bases on your 10fp. Their system has been around for over 75 years unchanged, so its pretty sturdy. Just don't put cheap aluminum "Weaver style" mounts on it. One piece of the puzzle you don't want to skimp on is the mounts.
