Probably silly question from newbie

So. I want to put a bar end mirror on the throttle side
I have the larger turmsio touring grips. My question is:

Do I just take a razor and cut the end of the grip creating a hole for the bar end mirror?

Or bore the end of the grip

Yes, on the throttle side you have to cut all of the grip away so it doesn't interfere with the throttle closing.

I don't know about the throttle side, but to accommodate the clutch side bar-end mirror on my Vincent, I heated up a properly sized (cheap) socket and carefully melted a hole in the grip end. It worked well.

That would reduce the chances of doing a ragged cut. The heated socket would leave it smooth like it were molded. Good idea.

There is no such thing as a silly question mate
Just ask away
I have cut the end of the grip with a knife
I think one time I tapped the end of the grip with a hammer until the handle bar came through, using it like a wad punch
But I may have imagined that

A grommet punch would be nice but they aren't lurking in every tool chest. You can make one from EMT conduit or iron pipe. If you sharpen the bevel on the outside of the pipe, the inside diameter will be the size of hole it cuts. So 3/4" pipe or conduit would provide a 3/4" hole. If you sharpen the bevel on the inside of the pipe then the outer diameter will be the size of the cut. EMT conduit is 0.92 inches, iron pipe is 1.050". A Dremel tool makes fast work of cutting the the bevel.

PS - for every silly question there are at least a dozen silly answers!

If you don't know the silly part is not to ask.

Doing the punch thing is my usual course of action because of the shakes and having trouble keeping my hands from twitching about, but I really like the heat method even though it probably wouldn't work well for me either.... I'd end up dropping it on my seat or gas tank anyway, so best use nothing hot.

This is an excellent solution.

Ive used a rubber mallet to tap the grip against the bar end on my Triumph. A bit of copper pipe etc can also be used off bike.
