Looking and trying the crimson trace laser grips I think they would be your best option. Once sighted in they should stay that way. What I like about the laser is you can shoot from any position and as long as the 'dot' is on the target, you should hit it. It is also a good deterent. I know if I saw a little red dot dancing on my chest I would definatel stop what I was doing and say Yes Mamm or run like hell.
