Which mounting plate will this use to fit on a hellcat pro? — 1 Answer

The Hellcat Pro will not accept the 407K or 507K models directly to the slide cut. The Hellcat OSP has indexing lugs on the slide that interfere. The rear indexing lugs would need to be removed and the front indexing lugs would need to be shortened as the 407K and 507K will not accommodate rear lugs and will only accommodate very shallow front lugs. There are some machine shops that will do the modifications, but this red dot will not fit out of the box. CHPWS makes an adapter plate that will convert your standard Shield RMSc footprint to the Holosun "K" footprint needed to mount this optic. The plate is available on CHPWS's website and will not require any modification to your optic cut.
