Thanks! My use will not be for self defense. I will use it mostly for plinking and some small game. I will also carry it along with my Remington 700 .308 for big game hunting. Having been primarily a bow hunter for many years, I am used to the stealth and close up shooting necessary with a bow. My last deer with a rifle was forty two years ago. My shoulders gave out so I am, at age 73, going back to rifle hunting but in the back of my mind is the possibility of a close up, ten or fifteen yard shot with my 617. That is why a laser sight is so intriguing. I live in Wilsonville, OR where Crimson Trace is. It is only three and a half miles from my house!
