Installation is not too bad. I'm far from a gunsmith but I've installed several sets of these on both mine and friends firearms. I think the hardest part so far has been removing the factory sights. The instructions that come with the sights do a good job explaining how to install them. I just set my file flat on the work bench in front of the vise, test fitted, then ran the sight the length of the file, test fitted, and repeated till it slid in about 1/3rd of the way in. Finally, drift it in with the included non-marring punch.
