I feel like I'm going crazy. I don't normally buy Crimson Trace anything, but I caught a 75% off sale for a Crimson Trace RAD (Docter footprint) and a Crimson Trace CTS-1550 (RMSc footprint). I was going to use the RAD for a PSA Dagger and CTS 1550 for a 365 XL. I reached out to Crimson Trace with no response so here I am. The CTS fits minus this little plastic notch on the back of it. There is a sticker under this notch that says "do not remove". Can I just dremel this off, or will it expose electronics? The Rad looks like it fits minus this bevel on the front of the Dagger. Am I missing something here? Nothing came with mounting plates.
