Have a quick question (I hope) that you all may be able to help me out with. I am building a CZ TSO as an Open gun for Steel Challenge. I already have a red dot, and I have a CGW frame mount on order. Last thing i need is a comp. I have seen a lot of threads about using the CM comp but I really don't want to hack my slide. I was wondering if anyone has a solution that does not include slide modification. EAA witness with a new barrel? Any assistance and or guidance would be greatly appreciated. Thank you.
