Recommended sights from SIG :
For 9mm and 357SIG : #8 front and #8 rear
For 40S&W or 45ACP : #6 front and #8 rear
Info found on another forum:
"For rear sights, the higher the number, the taller the sight. For front sights, the higher the number, the shorter the sight. This can be confusing to remember.
The easiest way to think of it is, numbers up, groups up; numbers down, groups down. This is true for both front and rear sights.
Each number change on the rear sight will affect POI 2" per 25 yds. Each number change on the front sight will affect POI 1" per 25 yds."
Hope it helps..
