Ya know I've been wanting those sights for months, and I recently made up my mind- instead of $100 for the xs (I wanted their BigDots) I'm gonna add a few bucks to it and get the rear-sight laser. When I really got to the serious part, layin' down the bucks, I just couldn't do it. I know ya need regular sights, too, but with the 3-dots and the laser..never mind, rambling now.
