True did not look closely at the pic of the target now that I did I agree not a sight issue.
What the heck is wrong with my P225?

You might want to try a new set of rubber grips and see if that helps. And have someone else shoot it to see how it does for them.

Think so but I'll do it again and snap a pic.

Shot some .358-.3585" MBC smallball reloads that my P226 loves through it. Better... at least I could hold them all on a 12" plate. I hit 14 out of 16 8" plates which is better... but I was having to go quite slow and concentrate. With my other pistols they are an automatic hit.
But better. OD of barrel is .531" consistently, so no bulge. Hood has some normal-looking wear but looks symmetrical with no raised edges or galling. The only thing possibly out of order is the FRONT edge of the locking block, from the front edge maybe a 16th of an inch back and a quarter inch wide, has a kind of galled-looking or raised bit, juuuust slightly higher than the rest of the surface. Can't figure that out... any ideas what would cause this? Is that surface involved in lockup anyway or is lockup only the barrel hood against the slide, with the recoil spring and guide rod pressing back on the locking lugs?
Will slug the bore tonight.
Pressing down on the barrel hood in lockup produces barely discernible movement.

Slugged the bore: .357-358" depending which groove you measure.

I don't we'll really be able to render a meaningful opinion until you try something other than bulk ammo

Bulk ammo is sufficient to produce excellent results in other pistols. I'm talking relative accuracy here. What ammo would be acceptable to you?

going to try some federal XTP 124 +P and 115 gold dots...
I once had a gun with a lot of slop between the barrel hood and slide. You could see as much as 1/32" of space between the hood and slide at lock up. The result was 10" groups at 15 yards.
An aftermarket replacement barrel with a much tighter lock up fixed the accuracy problem.

My default is Federal 9BP...only because I have a bunch stocked up. If a 9mm won't shoot with that I know there is something wrong with the gun.
Speer Lawman TMJ is consistent and still reasonably priced.
While my Federal is a 115gr JHP, usually a better gauge to base accuracy evaluation on is something in 147gr.
Generally I'd choose Blazer Brass over WWB or UMC

That's funny. I looked at a box of Speer lawman at the store and wondered if it would pass muster. I got the pricey JHP stuff instead.

I have a P6 and have changed nothing on it. I am not the best shot in the world (I do manage to put them in the mid section of the target ) and my groups are tighter with my P6 than any other gun I own.
This is a bit of a mystery. I have a pair of P225s and they both shoot really well. They are without a doubt among my favorite pistols. I also have a P239 which is a tack driver.
Let me know if you need me to shoot some targets as a comparison. I have a good selection of 9mm ammunition from different manufacturers and with different bullet weights.

I'm keen to find out what the fault turns out to be (it's not the shooter or the ammo)

I dunno about that... might still be the nut behind the trigger. 
The only thing I can think of to trouble-shoot it down further would be to find someone in your local area that has a P225 or P6 willing to go to the range with you (or just loan it too you for a while). You could then fire both first from a rest. You could then swap complete uppers next and fire both from the rest and see if the issue follows the your upper or stays with your frame. If it goes with the upper, put your upper back on to your frame, but then just swap out the barrels and shoot both and so on to narrow which part(s) are causing the problem.

This is really an interesting thread. It seems that it should be something wrong with the lockup or barrel. Have you tried some of the good SIG forums for advice? Something else you can verify is a simple plunk test with your bullets, just to make sure they fit. With a standard SIG barrel it should not be an issue, but it is something you can verify easily. If it plunks, and you can rotate the bullet while it is in the chamber, and then it just drops out, then it is something else.

I sent you a PM with a bunch of wear pattern pictures. Hope it helps.

thank you for the kind offer. I'm in Utah. Sigforum is stumped as well. I suppose I could send it somewhere but I'd really rather it didn't come to that.

If you compare your other Sig's when pressing down the chamber in lockup...is the problem child moving more? I only have a 228 and it pretty much doesn't move when locked up. If the chamber is coming to rest in a different place with every shot...I could see that you'd get vertical dispersion. Not sure about how a real Sig Smith would go about tightening up the lockup...but you might be able to displace a wee bit-o-metal to snug up the lockup if that ends up being the culprit.
Being a Police turn-in, it would be likely that it has been slide dropped on an empty chamber thousands of times when clearing. Perhaps this could have battered the ramp pushing up the barrel into lockup?

It barely moves. Like my other SIGs.
