Well I do think they are both great sights, you have a valid point ad far as a bigger sight maybe getting banged or caught up more. To me... the strikefire is super light for its size, I just feel it might look better on my SR22 also seems it would have a better FOV than the sparc, im going to do some more research kn both of these before I jump into a purchase, plus I gotta wait more than a week before I have the cash so it gives me some time. I wonder if I can find a pic of a SR22 with both a sparc and a strike fire, I think that would help considerably.
