I'm lazy and cheap. For sighting in any semi-auto, I made a target from a scrap of 1/4" plywood and a 12" piece of 2x4. Nail the plywood to the end of the 2x4. For targets, I just use a Pentel and draw a horizontal line on a sheet of typing paper and three vertical lines. Masking tape holds the paper to the plywood.
I set up at ten yards and get centered and an inch or two low. It's pretty easy to get on the paper and then get a better alignment. Then, go to 25 yards and get centered. For any centerfire, then, at 100 yards I'm commonly around three inches high and within an inch or two of vertical center.
