@RLSanders - if that 9mm is shooting low, try different ammo.
If you are using 115gr, try 124-125 gr. It makes a difference. When the 9mm was first developed, the ammo for which it was designed was ~125gr.
If you are using 125gr, try some 145gr.
Thank you. I’ll give it a shot. I used Browning Target ammo but don’t know the grain. It was $25 for 100 rounds.
