I sent my Colt Commander to my LGS to have the Wilson Combat Conceal Grip Safety& Hammer installed. While he had it, I requested my GS replace the front staked sight with a night sight. Well I got it back a couple of months later and the Grip Safety& Hammer looked and worked great, but the new front night sight wasn't glowing, so I had to return it. Well it's was about 2 1/2 weeks later and I got a call that the slide was ready. I picked it up, saw the sight was glowing, took it to the range and everything worked as expected. It wasn't until I got home that I noticed, my GS has not re-staked the replacement night sight, he cut in a dovetail! There was no extra charge, my GS said it was a much better way to go than staking and he wanted to do something extra because I had to return the pistol. I think it looks a little more classy.
