P320 40cal conversion
Good day, fellow Sig mates!

Looking for some insight here..

I built a P320 9mm but am wanting a .40... Do I need to buy a conversion or can I just buy the .40 barrel?? Or do I need a .40 slide as well as the .40 barrel??

Greatly appreciate your time!

If my memory serves correct, I'll need both barrel and slide?
Or am I thinking of 40 to 9?

Ok. If I understand your question correct.
You can not go from a 9 mm to a 40 with just a barrel change.
You would need a conversion kit that has a 40 slide , barrel and a new magazine for the .40

Now the other way of changing from a .40 to a 9mm could be possible with a aftermarket barrel change like from . Here

Yeah...need a .40 top end. I have a P32C 9mm. Bought a P320 .40 X-Change kit. Works just fine.

Did you go stock .40 x change kit or after market?

Stock OEM. Was an early adopter of P320 9mm back in January 2015. Bought the .40 X-Change kit several months later. Has always performed just as well as the original/native 9mm pistol. Accurate and 100% reliable.
