Hi from NE Ohio
Just learned about this forum the other day.
I have two G17's , a G17L a G34 and a G23.
I use the G34 for USPSA practical pistol in the production class. I have a C-more holographic sight on one of the G17's. I use the G17L for bullseye shooting.
I have only been shooting them about 6 months or so.
I have not done very much with handguns, most of my shooting experience is M1A and AR15 shooting the service rifle class of the national match course.
