Zero Range for a Glock 40 10mm

I just picked up a new Glock 40 and it's a beast. I'm going to be using it as a pig hunting gun with an Osprey 45 suppressor, adjustable suppressor sights, and an IR laser to go with NVGs; while pushing Buffalo Bore's 180gr JHPs.

Is there a specific distance I should zero it at?

The 10mm is a legit 100m cartridge. I wouldn't shoot a deer that far out, but I don't really care about pigs as they're a pest. I'm am SOT, so I may just slap a shoulder stock on it and really see what it can do.

That's a nice carbine you have there!
 
If you sight it to be at point of aim at 100 yd., you'll be just under 3" high at 50 yards. I'D be inclined to start with making it print 3" high at 50 yards, THEN test it at 100 yards to see how high/low it prints from point of aim. If you assume a 6" diameter kill zone on the hogs, you should be fine.

If you find that sighting it for 3" high at 50 yards makes it print much lower than point of aim at 100 yards, it's likely that your muzzle velocity is substantially lower than what Buffalo Bore advertises. If the M.V. is within 10% of advertised, you can sight it to be 2" high at 50 yd. This will put it "on" at 80 yd. and 3" low at 100 yd.

It depends on how much vertical deviation from your point of aim you are willing to tolerate as insignificant. Choose that deviation -- for big game hunting +/- 3 inches is often used. Then, find an external ballistics calculator and use it to determine the zeroed-in distance that gives a bullet rise no greater than your chosen vertical deviation between you and that distance.

As I recall, when I had a .270 Win, I would sight it in at 2 inches high at 100 yards. This would give me a flat shot -- +/- 3 inches above or below the line of sight -- out to about 230 yards. This is referred to as the maximum point-blank range. It will be much shorter for a pistol, but you may be able to get it out to 100 yd.
 
I don't hunt, but sight in my 10MMs, 9MMs, 38 Supers for center of mass at 25 yards. These shoot relatively flat, for a handguns, and enable hits at 100 yards, and a bit more, with minimal hold over.......ymmv
