In my humble opinion, your best bet is to replace your front sight with a taller one and then file it down until you are hitting where you want at the range you want to be dead on. I wouldn't sight it in at anything farther than about 50 yards and even that is a bit far for a .32. If it were me, I'd sight it dead on at about 35 yards.
When you go to order a new sight, they will want to know how tall you want it. Here is how to determine how much to add to your front sight. First, measure, in inches, from your rear sight to your front sight and let that be "A". Then measure from your muzzle to your target in inches and let that be "B". Now, measure how many inches you want to lower your POI and let that be "C". Okay, now divide "A" by "B". You will get a very small number. Carry it out to 4 decimels. Then multiply this number by "C". This final number is how much more front sight you need.
Here's an example: Let's suppose that you have a 42 inch barrel and the sights are 34 3/4 inches apart. Then assume that you are shooting at a target that is 25 yards from your muzzle. 25 yards is 900 inches. Let's also assume that your POI is 3 1/2 inches above your POA. So, to determine how much higher your front sight needs to be, divide 34.75 by 900 and you get 0.0386. Now, you multiply this number by 3.5 and you get 0.1351. So, in this case, we kknow that we need a sight that is at least 0.1351 inches taller than what you now have. When you call TOW or whomever you buy from you can tell them that you need a sight that is more than .01351 inches taller than what you have. They will tell you how to measure your front sight. They may want the measurement from the top of your barrel to the top of your front sight or they may want to know how tall your front sight is measured from the bottom of the sight base. They will also want to know some measurements of the sight base so they can send you the correct one that fits the dovetail on your barrel.
To remove your front sight, use a soft metal rod such as a brass rod or aluminum rod to drive the front sight out of the dovetail from the left to the right as you look down the barrel when you are shooting. The dovetail has a slight taper to it so it will have to be driven out the correct direction.
When you install the new front sight, take it to the range and fire a couple shots at about 10 or 15 yards to be sure you are on the paper. Then it is just a matter of driving your front sight in the opposite direction from what you want to move your POI. Small movements by making light taps on your font sight base using your rod and hamer that you used to remove the old sight. Once you get it centered, you are ready to start filing. Take a few strokes with a file counting the strokes. Then fire a couple ronds and see how much you have lowered your POI. Take a few more strokes with your file counting the strokes and fire again. By now, you will know how much each stroke of the file has moved the POI. Just keep doing thiss removing a slight amount of metal off your front sight until you have your POI where you want it. This is a matter of finesse. You do not want to hog metal off your front sight, you want to sneak up on the proper amount to file off. Take you time and enjoy the fun of adjusting your front sight. :thumbsup:
