Re: Before you replace your sights

What weight bullet were you shooting? M&P 40 is sighted in with 180 gr to hit point of aim at 25 yds. If you are shooting 155 or 165 gr bullets you will hit low. A good rule of thumb to remember is the heavier the bullet, the higher it will hit. So if you are shooting low with 155 go to a heavier bullet before replacing your front sight with a lower one. If you have to change you can get a taller rear sight to raise point of impact. Look at the Burwell or Dawson.
I am so glad I found this post and confirmation of what I though was to be true about my MP 40.
Just came back from the range with an almost embarrassing session. As a fairly competent shooter I was dismayed when my shots were all going low. I readjusted my grip, shot slow, readjusted aim and I couldn't correct my shots.
I was afraid that maybe my bore was off somehow or my sights not lining up right.
Luckily I searched this forum for some answers before running off and getting a stand and bore sighter.
As it happens, I was shooting with some new ammo. 165gr FMJ Winchesters that I got from Wal-Mart of all places. I had originally had poor experiences shooting with lower grain ammo, but thought i'd give this ammo a try, especially at 21 bucks / 100 rounds.
Anyway, I'm glad to know that it's not a major problem with my weapon and it isn't because I've completely forgotten how to shoot.
