CX 4 top rail mount?

[BerettaBill]

I have top rail mount ordered for my newly acquired CX 4. I noticed on the gun there is only one screw hole on the top. Will I have to have any holes drilled in the gun in order to mount the rail.

Yes, you'll have to drill and tap it. If you're not comfortable doing it, any local smith will be able to.

I've got a Drimmel and a power drill. I am pretty experienced/proficient with both in woodworking and home improvements. However I have never done any gunsmith drilling. Is there much to it or do you suggest I take it to a gunsmith?

The top rail comes with instructions on how to do it.
