A co-worker of mine just bought a new Para Ordnance Tac-4 double stack. He wanted to put crimson laser grips on it, however, being a double stack would make the grip to fat. I don't know anything about this model and I don't believe it has a accesory rail .

Questions: Para Ordnance Tac-4 double stack Laser.
Any suggestions for a laser on this gun?
Trigger mount laser? any good?
