Well, I have q DE, and I like it. But I'd second the no laser idea. There was one made for a short while that specifically fit it, but as far as i can tell it isn't made anymore and there isn't exactlya thriving used market for them. You'd have to go with any of the generic trigger guard mounted lasers.
I like my DE for the range, I could see hunting with it. I would never use the sucker for carry or defense if given a choice of something else. A laser will pretty much show off how much your hand shakes, and add more bulk to an already bulky gun.
Personally I'd put the money into more magazines (preferably older, as i picked up a couple and they are much less harsh on the fingers sharpness wise), or the high viz adjustable target sights, or the wraparound grips. All of which strike me as more useful than a laser sight for this gun. (heck or practice ammo)
