Over the weekend, I purchased a Beretta cougar mini .40SW. Among other brands, I’m a Beretta fan, And would like the availability to switch between .40 and 9 mm. Is it possible to switch these calibers? Are there manufacturers that make these conversion barrels? Has anyone converted a cougar in this manner?
My thanks in advance for your discussion And responses.

theoretically, you could swap barrels but that's not ideal. it's not common to find cougar mini barrels sold on their own so it's likely easier to just buy another mini in 9mm

I’d contact Beretta directly as I’ve never seen a Cougar barrel sold as an extra.

Does this one have the rotating barrel? If so I wouldn’t think you could swap...
