Probably have the 9mm perfected and strong market.
Try another caliber guns may not work as well need to change tooling etc. I’m sure if sales slow they may adapt.
With that said I just bought a tp9sf last week shot it and love it been eying them for about 2 years I’m a 1911 guy and impressed with the Canik trigger felt good gun shot good and accurate. Reliable as well. Great bargain my local places been sold out found one place who had some. I have a Glock 20 and 43 too but they are single purpose guns. If they come out with a 45 I may buy it too.
