I traded into this Colt from a member here on this forum. It had a some damage to the slide where it had been dropped. I was lucky that the damage was in a place that was easily removed by doing a simple meltdown to the slide and frame. I plan to use this as my new carry gun and love the meltdown look. So, this worked out great. I bought a Les Baer beavertail and a fusion MSH with magwell. Any thought I had on these parts being drop in was quickly shot down. The magwell had to be fitted to the bottom of the frame and the well had to be beveled into the frame. It took me about 2 hours for this. The beavertail was a major project. I had no idea what I was getting into. I took it out of the box and there was no way this thing was going into the pistol. After a little research, I found out why. It needed to be hand fitted to the pistol. A better statement is that the pistol need to be cut to fit the beavertail. 6 hours latter I had it done. Just need to hit the pistol again with the bead blast. So, if you take pride in your own work, give it a try.
