Sig Pro mags.

Does anyone know if Sig Pro mags are the same between the 2022 and 2340 pro models?

I think I remember reading on here that all Sig Pro mags are interchangeable.

Edit: Found it

They have their own mag vis-a-vis the other SIGs, like the P229. I believe the SIG Pro mags are interchangeable between the SP2022, SP2009, and SP2340 - even between the three calibres.

The 9mm SP2022 and the (9mm) SP2009 mags are definitely interchangable (in fact they are the same, as I understand it) - as are the .40S&W and .357SIG SP2022 mags with the SP2340 mags.

You can get them from Brownells (under "Factory Parts" then "SIG"). Some Canadian sellers probably have them as well.
