P07 issues - sight drifted pretty far right

I did everything in the first tuning thread yesterday afternoon.

I will look in to the disconnector clearance. I fired another 50 rounds today. Groups were better, but still about twice what I do with my SP01.

Backstrap is what ever came on it


I'll post pcis later. The sight position bugs the hell out of me. But it feels really controllable.

Whats the budget upgrade here? springs and a roller?

I tried different ammo, no real change. I fell like Im shooting well but then I get a group all over the place.

You might find a fired case that has the most centered primer hole (looking from the front of case). Then put that in the chamber  & using a good light source look down the barrel from the front.

Line the barrel  primer hole up to be centered on the barrel crown hole, now without moving the gun see if the front sight lines up with the rear notch.

If it all lines up then that is where the rear sight needs to be for POA/POI. If the rear sight notch is off to the right then it is probably your trigger control or hand to grip position.

Since you have the suppressor sights, another thing to check is your front sight.  Is it straight up and down vertical relative to the grip or tilted to the right when viewed from the rear?  See if it is straight in the front dovetail.  Just a thought.

medium backstrap may be worse?

WTF is going on here... Im really starting to lose my patience with this firearm.

So I think I may be on to something.

On a whim, I dug in the cabinet and pulled out a box of 115 gr tula brass max . (I shoot reloads almost exclusively - mostly 147's over TG, or 124's over ETR7 or E3 or 231) I only have 147's at the moment.

I loaded up the tula brass max 115s and got this

5 rds each diamond as usual


10 rds


Now - these reloads work superbly in every other firearm I own. Why would they NOT work well in this gun? What could I be missing here?

Switched back to the 147 reloads and got this 5 shot group:

 what distance are you shooting?

I think the P-07 Urban grey normally come with the Small backstrap installed. What size(glove) is your hand?  You may find simply changing the bacstrap will tighten your groups. Hey, it's worth a try and costs ZERO$.

I went into the range yesterday to buy a target prior to shooting and mentioned I liked the Range Officer course I took, but should have used my S&W as I am still trying to get use to my P07.  One of the range personnel asked what back strap I was using ..I said the small due to my hands not being all that large.  He changed the strap to the med one (mine has no lanyard) he showed me how much of a PITA it is with out the lanyard and my grip became much more comfortable and the range results were amazing. It gave so much more area for my support (left hand) to grasp.

Something is not right.

Even my 124's suck in this gun. Different seat lengths, etc etc. Nothing works. But by god it will shoot those 115 Tulas like lasers.

Don't understand the problem with ammo unless All You Shoot are your own reloads. I haven't had any problem with 115 124 or 147 Freedom Munitions or federal hst 147hp

[Borsig]

pretty much all I shoot. yes.

I may runs some HST thru it just to see.

every reload I run thru it is trash. Im going to try some WWB next?

I think you answered your question when you said
"" every reload I run through it is trash"" !!!
I think you better double-check how you're loading..
Truth is I know nothing about reloading but sounds like a problem.

[Borsig]

Then why does every other gun I run these in shoot them like tacks?

THAT is my point - If other guns did this - the problem would be obvious. They dont. Ive been using these recipes for years with no issues.

[Borsig]

WWB. The one flyer was my fault - its getting dark here - storms brewing

124's after adjusting the OAL to match the OAL of the Tula 115's
