What do I have to do to my 365 to get a six o'clock hold sight picture instead of the dead on "combat' sight picture? I really like the X-Ray sights, I would just rater have it regulated the same as my other handguns.
I am not particularly interested in changing colors or anything, although I do like Trijicon sights on other pistols.

Thanks,

A taller front sight would be required. Too many variables to determine which one would work. The size of the target's bull would make a difference.

And of course the distance to the target.

Wouldn't he need a lower front sight?

Just like a rifles front sight.
Up is down and down is up.
Screw it down to raise the impact and turn it out to bring it down.
Sig pistols are 1" per. 010" @ 25 yds
A #6 front is .230" and # 8 is .220"

The rear is opposite.
Taller raises impact and shorter lowers it.

So is that a lower or taller front sight?

I find this site (no pun intended) to be helpful. While I do have Dawsons on a few of my pistols, no connection to the company.

A lower front sight will raise the point of impact (assuming, of course, conventional sight alignment).

A six o’clock hold involves aiming lower than the desired POI while using sights regulated to hit higher than the point of aim.

The usual reason for a six o’clock hold at the bottom edge of a conventional black bull’s-eye target is because if the front sight is also black, black on black makes it difficult to know exactly where the sight is aligned on the target. If, however, the sights are regulated so that aiming at the bottom edge of the bull’s-eye results in the bullets’ hitting the center of the target, then the “pumpkin on a post” sight picture will provide more precise and accurate results.

A lower front sight also lowers POA, which is what he wants if going from a combat hold to a 6:00 hold.

Use one of the on line "Sight Calculators".
Google search on "Sight Calculators".
There are several to choose from.

Basic measuring and basic math wins the day.

Not necessarily. The point of aim is what the shooter chooses. Regardless of what sights we have, we can aim wherever we wish. How the sights are regulated will then determine where the bullets impact.

If the sights on a gun like the P365 are regulated so that point of aim = point of impact (as they should be), but the shooter wants to hit higher than the POA (e.g., to use a six o’clock hold), then he will need a lower front sight and/or a higher rear sight.

Well, I meant it lowers POA if everything else remains the same. Obviously if you change what you're aiming at, it's different.

Anyways, I think we agree that to go from combat hold to 6:00, you need a shorter front sight (or taller rear sight).

Yes, we do.

Anyone with an Idea of what number sights I should order?

I wouldn’t be confident that you will find what you need in fixed sights, but in order to perhaps answer the question of what would be needed, it would be necessary to know the size of the bull’s-eye and the distance to the target.

Additionally, if you intend on staying with the X-Ray sights, it's going to be tricky since Sig does use combat sighting. They weren't designed for sighting over the top, so you'd have to take some measurements as to where the gun's POI is with the current sights using a 6:00 sight picture. We know it's going to be lower, but the question is how much lower?

When you use a 6:00 sight pic on the gun with the current sights, how low do you hit?

If your 365 has a #6 front sight (it is marked on the sight) then going to the #8 front sight should raise the point of impact by 2 inches at 25yds according to a Sig sight adjustment graphic I downloaded from somewhere. For the xray sights I think they only make 6 and 8 front sights and 8 rears.

Obviously it’s your gun and you can do whatever you wish but I have to ask. On a clearly ccw style small gun why would you want a 6 o’clock or bullseye style sight picture. Unless your goal is to shoot bullseye matches with a pocket gun what is the point? I wonder if what you are looking for is more of a tip of front blade impact rather than drive the dot. And yes you need a lower front blade.

Yes, according to the SIG site, the X-RAY3 sights are available only in limited sizes. At one time fixed sights for the Classic line guns covered a much larger range, up to 9 at front and 10 at rear.

I don’t know what sights are standard on the P365, but I suspect it’s the common SIG 9mm standard of 6 at front, 8 at rear. If one could change that set to 9 and front and 10 at rear, that would raise the point of impact by about* 7 inches at 25 yards, or about 4.2 inches at 15. Depending upon the size of the bull’s-eye target being used, that could be sufficient for use with a six o’clock hold.

Unfortunately, anything other than 6 and 8 either front or rear have always been uncommon at best even long ago when they were still mentioned in factory armorer manuals. And of course such sight sizes are not available in the X-RAY3 line. Changing the front sight height from 6 to 8 would raise the point of impact by only about 2 inches at 25 yards and about 1.2 inch at 15.

All this discussion is of course applicable only to the SIG sights. For example, I discovered that when a Trijicon XR front sight only was used with a factory P220 rear sight that the POI was changed by several inches at short range. I can’t recall now if it was up or down, but something like that might be a solution.

* I say “about” because the 1 inch per front number and 2 inches per rear number have always been cited in factory literature for all Classic line models regardless of slide length, but the actual effect of changing the height of a sight varies based on slide length. The shorter the slide, the greater the point of impact difference would be for any particular height change.

Sig guys, Thanks!
I believe that if I change the front sight from a 6 to an 8 I will accomplish what I am after...which is bullet holes appearing right on top of the front sight at 7-10 yards.

Thanks!
