Today was my first range day with my new glock

At 10 yard it shoot like 6 inch too low , i got the glock factory night sight on it ,
I try to bench the pistol with sandbag , sane thing shoot to low

Any idea how to fix this ?

ok, before your edit I thought it was new with factory sights on it, from the factory. So did you put on a different set?

You can compare the height of the sights to see if they are the same. Even a very tiny difference can make the shot be way off at 10 yds, even if you perfectly pull the trigger without moving the muzzle.

Interesting. The Shadow will shoot a bit high with 147 grain bullets, so they recommend a FSP change. Seems like your Glock may be the same. Call them to confirm.
 
One more question:

Are you aligning the three dots, or the flat black tops of the front and rear sight posts?
 
What sight picture are you using? Sounds like perhaps you’re using a classic bullseye sight picture with the sights leveled at the bottom of the black rings on the target.

Heavier bullets will generally shoot high in 9mm, it isn't a manufacturer specific "problem". The OP states that 148gr is dead on which means the gun is shooting low if it's being shot properly.

I see it a little differently, (or maybe the same), but what if Glock put on sights from the 147 grain parts bin? Then technically all is well. Same if I changed the sights on my Shadow to work with 147 gr bullets, and then it would shoot low with 124 gr.
