For that pistol, I'd go black, or black w/silver flames. The last one was discontinued, but you might be able to find a set on Ebay.
Laser grips are quite useful for not only training, but for self defense. Those who are not truly experienced pistol shooters, like me, are likely to forget the tennant of "front sight, front sight, front sight". For that reason alone, a laser sight is extremely useful. If they were useless, the military wouldn't be using them on rifles in many cases.
That said, I do feel that it is important to not become dependant on the laser sight; it will only degrade or destroy what sight skills you have if you do so. When I would run my dry fire drills, I always started with sights alone, and then went to the laser to check my steadiness; it will quickly show you if you are pulling off of target.
