Made my first trip to the range with my new P365XL today. Shot 100 rounds of 124gr Blazer and 20 rounds of 124gr Sig V-Crowns. POI seemed consistently low with both.
Presumably, Sig calibrates these to have POI be POA at 15’ using combat sight picture. I replicated that sight pic, but was at approx 21’.
I am certain that the operator is to some degree at fault. But, is it all me or are Sigs low shooters?
My sights are numbered 8 on rear and 6 on front. Is that the standard sight setup?

Will continue to practice, but looking to hear what others have experienced. TIA

#6 front/#8 rear is standard issue on P365s. Many shooters find Sigs shoot low if they are used to using 6 o'clock hold or center hold. With Sigs, the front dot is supposed to cover your target.

There was a thread a few months ago from a member who had the same problem you did. Replacing his front sight w/ a #8 fixed it for him.

I'd say have at least 1-2 competent shooters you know shoot your gun from a rest and see if they experience similar low POI to see whether it's you or the gun.

This is a little bit of a tangent, but one of the advantages of red dots is that their adjustable. You don't have to live with the factory sight calibration on fixed sight guns. You can dial them in how you want them. And, yes, I know you can get aftermarket adjustable irons if you wanted also.

Maybe someone can chime in on my thinking on this issue. But I think with iron sights, you have to figure out at what distance your POA equals your POI for your ammo. Then see where the POI changes with distances shorter and longer than where the POA = POI to give you an idea of how much to adjust as needed by the distance.

My first couple times out with my P365X (same #6 front and #8 rear) seemed to shoot low. Recently had it with at the range and was quite surprised when it seemed on target. First time shooting my P226 Pro-Cut (just bought in January) seemed about 4" low! Need to get out with that one again. The P226 has #6 front and #6 rear? I know more shooting time is needed; I also know I'm not the best shot but probably more because I had many years of just working and other things that kept me away from shooting.

Just this year I've bought three 9mm pistols, and a fair bit of ammo. This has rekindled my interest, so I'm hopeful for improved accuracy.

A lot of things can contribute to vertical POI. Most every Sig I've ever shot with OEM sights were configured as combat hold, where the sights completely covers the target center rather than intersecting it. Good or bad, that's how they are, and I personally got accustom to this configuration.

Smaller lighter guns like the P365 series invite recoil anticipation which will push hits lower. If this is the case, it can be corrected with practice.

For an XL?

I went through this six mos ago and posted about it. I have a P365 and a P365XL. AFAIK, there are no replacement rear iron sights for the P365XL. The MOS plate does NOT (edit) have a dovetail cut. You have to go red dot. It'd be nice if someone made an aftermarket MOS plate with a dovetail, as I prefer Trijicon Bright and Toughs on all my carry guns. But I have been working with my Holosun and am pretty accurate with it. I just have a natural aversion to battery-powered stuff on carry guns.

That’s why you buy the X Comp version. Yum. They have separated the dovetail from the optics plate.

I just shot my new Xl today after no shooting for about a year.
I agree, the sites, if all three dots are aligned perfectly, shoots low. I adjusted to putting the top of the rear site line at the center of the front site dot and that's pretty close.
Doing that, the thing was instantly amazingly accurate and a wonderful gun to shoot.
I put a Magguts +2 in one magazine to try and it had 2 failures to load the last round early, but none later. I may use the 12 round standard version until I get to shoot more to be sure it was a break-in issue. Another way to look at it is that using the +2 with the last one not loading is like carrying a +1 since it had no problems until the final round and it didn't jam, just slide locked back open like an empty mag would normally do.
I shot around 150-175 rounds of a variety of ammo that ended with the Gold Dots I intend to carry.

I've got a lot of Sig handguns and most of them don't shoot low, but a couple do. I'm not sure why that is though.

The iron backup sights on my 365 Romeo Zero shoot to point of aim, though.
