adjust sights

What ammunition are you using and at what distance are you hitting high? Have you tried ammunition other than what's hitting high for you?

All other things being equal, if your sights were factory regulated with "high speed" ammunition and you're shooting lower velocity stuff hits will be higher.
 
^^ Along the same lines, bullet weight can make a difference. If the gun was factory-sighted for 115-124-ish grain rounds and you're using 142-grain stuff, your POI (point-of-impact) will be lower than POA (point-of-aim), too.

Once you determine that your gun is indeed "shooting high" with the ammunition you intend to carry, to get it on POA, the rear sight needs to be shorter, or the front sight needs to be taller. I'm not sure about the 24/7 sight's adjustment abilities (if the rear can be elevation-adjusted.)

Yes, used a rest , 10 yards and triedseveral types of ammo (brands and weights).
The rear has two white dots and the frount blade has one white dot. I don't see and elevation ( up or down) adjust at all. I think it will have to go to a gun smith to change the the sights. Thanks for the replies

If your gun is truely shooting high, you need to either raise the front sight or lower the rear. I you have fixed sights, the cheapest way is to replace the front sight.
 
Before changing anything, move your target to 7 yards (21 feet) that is where most guns are sighted in to. Also try putting your 3 dots just under the bullseye and try a 6 O'clock hold.

Good luck

As another of the responders noted, lower velocity ammo (which tend to have heavier bullets) will tend to hit higher...

That's because the barrel lifts more with recoil before the round has left the barrel, which has the effect of raising the point of impact.

I've personally not shot enough of the heavier rounds to ever notice that much difference with my guns. (At first this explanation seemed counter-intuitive -- that a heavier bullet would hit higher -- until I considered recoil and barrel tilt or lift.)

RE: original post...

1) Get someone else to shoot the gun, preferably an experienced shooter.

2) Move your target closer and use a rest, to make sure it's the gun and not YOU causing the problem.

3) Check your owner's manual to be sure you're sighting properly for your model. As suggested above, a 6 o'clock (sight picture/target) hold make be the easiest solution.

4) if you're using a heavy round, try 115 or 124 gr ammo (assuming your gun is 9mm).
