Since my last post in this thread I've removed the medium back strap from my 19 and I've been practicing dry fire.
The distances at my range are marked but I'm not sure where they start the measurement. I was shooting from approximately 8 yards. I drew from concealment and fired two shots each time.
This is the beginning starting cold. The first 5 shots

This was halfway through. Still 8 yards with Blazer Brass 124 grain.

This is when I changed targets .

And this is the end

One thing I've noticed is that whatever I'm doing wrong I am apparently doing it very consistently because I appear to be hitting the same point over and over and over and over again it just seems to be to the left.
ETA: The target is 18 inches tall by 12 inches wide.
The Gray is 4 inches wide
The orange is 2 inches wide by just a little over 3 tall
