Sig P-6 owner, chime in

[Mity2]

I'm trying to find some night sight for my Sig P-6.
My factory set is 8 on front, 7 on rear. I was told that typically, a .357SIG or 9mm will use a #8 front and #8 rear - .40S&W and .45ACP will use a #6 front and #8 rear.
So there for I can find boat load of #6 front and #8 rear, but I can't find #7.

What does everyone else's sight #'s on your P-6?

This isn't exactly the answer you're looking for, I'm sure... but my experience is that a change of one number on the front sight isn't going to make that much difference on POA/POI at most reasonable distances.

well, what do you define "reasonable" distance?
And whats the actual hight difference between say, #8 and #7?

Each number in front sights reflects a change of .005"

Each number in rear sights reflects a change of .010"

A #6 front shoots lower than a #7, which shoots lower than a #8. But as you can see, it's not at all a dramatic difference.

It's hard to estimate how much it'll affect your POI because I don't know what the sight radius is on a P225; however, if you have that number and understand basic geometry, you can get a rough idea on how far the POA will move at a certain distance.

Doing some quick math... let's just assume that your sight radius is 6". Dropping the front sight .005" will only drop point of aim .750" at 25 yards. I don't know how good a shot you are, but it's a damn good shooter who can shoot off-hand at this distance and realize that they might need to tweak their aim 3/4 of an inch.

By reasonable distance... I kind of meant something like 20 feet or less. At 20 feet, you're moving point of aim by two tenths of an inch. If a fly farts on the other side of the room, it could blow your bullet off by more than that.
