I don't carry this gun so I wanted tighter sights as the battle sight to quote someone from another forum "you could drive a bus thru it". The front is gold bead already, but the .165" wide battle rear the front just gets lost. I shoot for accuracy and competition with most of my guns so I did tons of research and settled on the adjustable rear Kensight. This one is .125" wide like most sights. I spent 2.5 hours fitting it and it came out great. It was definitely oversized as the measurement across the base width was .497" which is per spec, but the Wilson sight measured .473" and drifted out very nicely. So I had a bit of work to do to make this fit without touching the slide of course. Can't wait to get it to the range and I'll report back. I expect much tighter groups now! Also in fairness the battle sight is just that, close quarters protection and it does work quick.
