What kinda holster are you using?
If anybody is lacking a printer or B-8 the 9 ring is about 5.5".
Good point about making your own targets.
My holster is a paddle holster from G-Code Tactical Holsters. (

Much of the year it's fairly dark when I am walking to/from my vehicle, hence the light. People get quite upset at some decisions that I make, and I fully believe that they are capable of attempting something stupid as a way of expressing their anger.
In my experience guys can/do slow down with lights and optic but only if they stay with their traditional type draw.
If you're stuck in forward cant mode and raise your front sight to eye level in an arc, lights and optics cause problems. But if a guy uses a proper draw that comes straight up n out, there is no change in the time it takes to put first round on target.
If anything, they get faster.
