    i jus tbought a used hk usp compact .40. i allready own one and bought this one as a ccw/car gun. i took it out to the range to see how it shot. the gun shot very low (about 4 in. low) and to the left. i know i can correct the left by drifting the rear sight but was curious if there was an easier way to correct the low shots than changing the front sight?

    You might want to try a few other brands of ammo before making any changes (unless what you shot is what you intend to always use).

    Guns often have a preference for specific loads and maybe you were using one that was a bad match.

    If you need to shorten the front sight, here are a couple of options:

    Find something hard and flat to place over the rear sight. Use that as a guide to to file the sight. You can also cover the rear sight with tape, cover the rear half of the file with tape (one piece parallel with the file. Rub a little grease on the tape and lay it on top of the rear sight as guide. The trick is to be CERTAIN the file is square with the front sight.

    The easiest method is to use a drill press. Remove the slide and place in a machinist's vise. Place the vise on the drill press platform. Chuck a small flat grinding wheel in the drill and trim away. I use a Dremel wheel. Again, the trick is to be sure the surface of the grinding wheel is square with the front sight.

    I have successfully used both methods. If you need, I can email a couple pixs.

    thanks for the advise. i tried both wwb ammo and federal hydrashocks which i use in my other usp compact and the results were about the same. if i shot at the center of the target i would hit the bottom, if i aimed at the top i would hit the center. i used 9in paper plates and was shooting between 7-15 yards. so i'll most likely try the grinding method first, if i screw up i was going to have to get a new front sight anyway. thanks for the advise everybody.
