So, a couple weeks ago I go to my gun range with two of my Ruger P95's and my Sig P226.... shooting at about 15 ft I'm 3" to the left and so I adjust all three pistol rear sights over to the right and get everything pretty much on center... then later on that night I'm looking at one of those correction targets that shows what you are doing wrong that causes a round to hit off center...and I start thinking.. how could all three pistols shoot the same to the left? Chances are it was how I was holding the pistols that caused this... and so I go back today and shoot the Sig with it sitting on a pillow... yep... everything is to the right ....... So, I knock the rear sight back over to line everything back up... was shooting at 50ft today. Trying to get the Sig right for the class I'm headed to the first of Dec.
