looks like avery ncie build there,. I had a few fo the rem factory guns(xp100's) , have to admit I don;t think I ever got very good at shooting them LOL
or not up to what they could really do

few friends I have had some built up, and boy, they always impress-me with how accurate they are with them,
I love long range shooting, but mostly stick to my rifles for it once distance gets past 200 yards any how!
takes a lot of skill IMO and practice to shoot far with hand gun , out far as you have been doing
my hats off to you!
keep up the good work!
