I prefer a compact light/laser combo.
I may still buy Laserlyte's laser mount without the laser and cut the lower section off so I can mount a short picatinny rail to the underside.
Frankly, it perturbs me greatly that many firearm manufacturers are so concerned about making a few extra bucks that they lock us into a very limited or virtually nonexistent range of choices for add-ons. They make it a PITA to modify what we really want to fit their guns. They really need to think about customer satisfaction and loyalty rather than that little bit of extra profit. In fact, my inclination right now is to never again buy a firearm that doesn't have standard common Weaver or Picatinny rails. >
