This may sound stupid but everyone keeps telling me that my P239 .357 can be converted by simply changing the barrel. I get that part. What I am unsure of is will the 40 SW fit in my magazines? My mags actually say sig .357 on them and I've seen online ones that say 40 and others that say both.
Is there really a difference?! I mean its the same cartridge, so it should work, right?
