I have a beretta 92, the sights are fixed. My gun shoots strights but the bullets hit low. To hit where I'm aiming I have to have the white dot on the front sight above the dots on the rear sight.

I'm thinking it might be the trigger pull.

When the hammer is back ready to fire, I really have to put the squeeze on the trigger to release the hammer.

I have a S&W Model 629, that when the hammer is back I just barely put any pressure on the trigger and it fires.

Does anybody know how I can lighten the trigger pull on my Beretta? Trigger kit? Spring kit?
