guess my question would be, have you shot it yet? If so do 'you' have any concerns on flash?

I have a PC Shield, and in darker inside range lanes have not noticed much if anything that would concern me. Not saying it doesn't exist just that for my needs it is a non factor.

So my humble suggestion would be to run some ammo thru it in it's stock format and see what you think and feel about it, then go from there.
