Great metal night sughts
These sights are nicely machined and with some of the brightest tritium in the industry.... The original factory sights were a little stubborn to remove with the nice supplied punches, plus I was doing it at the range in Alaska where it was about 12 degrees F tonight. I eyeballed the centering of the front and rear replacements and then put several magazines through a S&W Core Pro. I always worry about non adjustable sights patterning too high or too low for me but these babies were right on at 20 yards. I'll see what they do at 25 and maybe 30 yards tomorrow in the light as it is getting dark up here at about 4:45..
I have to highly recommend Dawson's sights. If you do this as often as I do for myself and customers I would invest in the big MGW professional sight pushing tool with the inexpensive "shoes" for every pistol you work on. I got mine at Midway when they were on sale for about $350 a couple of years ago.
