i have installed several sets of XS sights. i love them but the front sight is somewhat tricky. like installing any gun part that requires filing to achieve the correct fit, you must go slowly.
i am not ashamed to admit how many i have ruined by being too heavy handed on the file. the bottom of the the XS front sight is 'U' shaped, not flat, so filing removes material quite a bit faster than on a simple flat surface.
the trick i use is to place my file in my vice and then gently run the sight across the file. if you put some color on the bottom of the sight, you will notice immediately if you are grinding flat.
XS sights rarely take more than a few light strokes to prep them for installation. as with anything, reading the instructions iscrucial. you will notice that they say to remove just enough metal so the sight just starts in the dovetail. put the unfiled sight in the dovetail and make a small mark to indicate how far in it goes, take a few strokes on the file and try again. compare marks. when it just starts to move into the dovetail, you are done filing.
pounding the sight into the slide before it has been sized correctly will be an exercise in frustration and you might damage either the slide or the sight.
the plastic 'punch' supplied with the sight is useless for all practical purposes. i use a brass drift with a piece of tape on the end.
if you manage to take too much material off the bottom of the sight, don't fret. i have done this at least twice. go to the nearest auto parts store and pick up a set of feeler gauges. cut a small piece of the .003 and place it under the sight as you push it in place. you may need to experiment with different thicknesses of shim to find the proper one. make sure you cut it smaller than the width of the sight so it doesn't stick out.
it should be hard to push the sight into the slide. not pound on the hammer hard, but it definitely should require some effort to get it in place.
i dropped the $100 for a sight pusher -- which is an invaluable tool if you do this a couple of times. sweating to hit the sight in the right spot is very stressful. if you nail your slide or the top of the sight you are going to feel miserable.
i can't overemphasize the notion of just taking a very little material off at a time with the file. it may take you an hour to fit, but you will be very proud of the effort and the result.
