Hi all, just picked up my first ccw pistol (Glock 19 gen 6), went out shooting with it today and had a issue with my eyes blurring the iron sights together so I had a hard time seeing the target.. should I get a red dot for it, if so what do you recommend or should I change out the irons to a blacked out rear and something bright for the post..
Thank you
