help!! :-? my STI .45 with its dovetailed fixed novak night sights is shooting 2" low from its point of aim...what can i do to make it shoot dead center? thank you happy new year!!!

You probably need to install a shorter front sight. Novak has front night sights available in several heights. If it's a relatively new pistol and it came that way from the factory, you might try calling STI and see if they'll fix it.

or file it down slowly

You can try going to a heavier grain ammo if possible. If it's a .45, they probably sighted it in for 230 grain. If you shoot 180 grain, it will hit low because the bullet accelerates faster and leaves the barrel at a lower point of the upward recoil arc.

after replacing my front sight with a .165" height...it shoots now 1" from point of aim using 200 grs. SWC.

should i go for a .160" ( my rear sight is a fixed novak)

thank you :cry:

If you are sure that is the ammo you will always be shooting and the low effect is not due to operator, then I suppose you could lower the front sight again.

The sight radius on a 5" barrel 1911 gun is approximately 7" if I recall correctly, so getting POI to come up 1" at 25 yards would require a change of:

7 / 900 = .0077 (7.7 thousandths of an inch shorter front sight)

So a sight that is .005 shorter should get you REAL close.

For me, within 1" would be good enough, but I guess you want it dead on.

I would send the whole gun to Novak who will sight it for you and maybe even install one of their great gold bead front sights which I highly recommend. Novak is a great company to deal with>
