S&W M&P Pro 5" 9mm & M&P15x Range Day

I am going to shoot my M&P 5"Pro9mm this weekend in a competition so I thought I would get some practice at 10 yards. Looks like I should aim left.... My M&P 15x needs to have the iron sights checked after putting the rear flip up sight back on and taking off the optics. I start shooting at the center & try to work down 1" each shot. I never adjusted the sights, just my POA. Thanks for watching & please comment, like, favorite & subscribe. Peace
