My first red dot was a cheap one I picked up to try on a Ruger 22LR pistol. After some adjustment I started to really like it. I put it on a SW500 and it only survived one 5 round volley. I picked up a Leupold Delta Point Pro recently and mounted it on my HK45. I’ve not really put it through significant testing yet, but I really like it so far. It allows me to practice aiming and eye discipline without firing a round.
