Here you go, between the ice we have going on I got out to the range today. Was a ton of fun to push for accuracy. Long time precision rifle shooter, but never did this much with pistols.
My red dot was a tad off, I was shooting left, but did pretty well. About a 2" group minus my 4th shot at 10. Got excited and didn't focus on trigger press and pulled it off. I shot a 5th but know that doesn't count.
Just because I like to win, I tried it with my 686. It's old and love that gun. I think I got you with that gun. The way I measure it, right at 1.605"!!!!
Now I will agree not really in the spirit of your challenge. However, it's a no dash gun, so technically it was a carry gun when it was made
Thanks for the challenge it was fun and think I'll add in a tad more accuracy work during my range times. I will get my red dot a little better zero and I may be able to get all 20 in the X ring
