I ordered the Holosun 507K Green sight for my CZP10-C Optic Ready 9mm with the corresponding CHPWS mounting plate…….perfect fit, no play in the plate and slide or with the mounted green dot. Lots of extra screws already dabbed with blue locktite. Great dealing with Freedom Gorrilla, very happy with the price and service. Shipping was quick. Very satisfied with their service , advice and pricing.
