Red dot

Best optic to put onto my 47 mos?

I’m looking to put a red dot on my 47 mos but am stuck between a few. I’d like to enter a pistol competition by the end of the year with it so ideally something that’s good for the range that still will work good in a competition.

Not worried about concealing it but also don’t want something that’s as big making it look like a rifle red dot on a pistol
