While I'm waiting for my can to come in I'm trying to get my g21 gen 4 ready and have read a lot of different things about suppressor height sights vs regular height sights. I will be shooting the gun suppressed and unsuppressed so would tall sights affect my poi without a can on? I know I may have poi shift with the can. Should I just get regular sights and shoot through the can? Should I be looking at getting adjustable sights? Just a few questions I had I don't want to buy something and regret it later.
