If any of you have had a chance to really compare the two, your opinion would be appreciated. I am thinking of one for my Glock 27.

I'd go with neither. I've found picking up the dot is much slower than a normal front sight picture, especially under many lighting conditions. Ended up I've got 600 bucks in laser grips that I don't use at all. Just an expensive novelty. Other than that, I think Crimson Trace makes a nicer product. But that's just my 2 pence.

I do like Red Dot and Holo sights and I've found lasers to be near useless for me. Playing hunt for the dot instead of just putting the sight post where needs be.

I suppose they might intimidate some people in some defense situations but they might also point right back at where you are standing in other situations.
