(I will preface this post by admitting I can be an idiot from time to time)
I spent the day at the range with my 3 P239s today - I realized awhile back that two of them always shot low - well of course they shot where I aimed them... but for some reason with the same ammo and the same shooter (me) at the same distance. One was perfect, well close enough - slightly low and to the right 1" or so... at 7 yards (21'). The others were at least 4" low at the same distance.
I could not remember which ones shot low, so went thru 200 rounds, wrote the serial numbers on each target so I knew which gun went with each target. And rotated thru the group twice, I mixed them up as to not get used to shooting one gun more than the other.
One is a SAS Gen 2 - One is a new one I bought a few years back and rarely ever shot, and one I picked up at a pawn shop used. Of course the one from the pawn shop was the one that I could shoot the best.
In the end - the two I had bought new, that I consistently shot low with had #8 rear, #6 Front.
The pawn shop gun had #8 rear, #8 Front. Not sure if it came that way of if the previous owner swapped them.
I just ordered three SIG SAUER Tritium Fiber Optic Front #8... I am hoping they all aim the same after I am finished.
I also have a P229 - it is a tack driver - but that has an adjustable rear sight that I have adjusted to its max. And a P938, which is perfect as well...
So not sure why the two P239s ar setup that way.
Ooh, and one of the reasons I am an idiot in this case - After I placed the order, I went looking for my sight tool. I found it, and in the box with my sight tool was a new set of #8 and #8 night sights, still in the bag. I must have figured this out years ago, and forgot.
