So I finally got a 357 Sig barrel for my S&W M&P 40. I took it to the range yesterday and shot with both barrels at 5 & 10 yds. At 5 yds, not a huge difference in point of impact. However, at 10 yds, the 357 Sig consistently shot about 4-5" low compared to the 40. Since the gun is originally a 40, I know the sights are meant for that caliber and I figured there would be a difference in POI between the two calibers.
Does anybody else swap between the two calibers in the same pistol know some tips? Do you just keep the POI difference in mind and aim differently with the different barrels? Or do you do something else to account for it?
