What is the difference between a CA Compliant pistol and one that is not? Specifically wrt to a P239.
The P239 is still in its original form from when the roster was created. Hence, the roster listing for it is vague (just as all SIGs were originally), and the gun has been unchanged. It continues to be grandfathered as SIG continues to pay the fees. Several SIGs (P225 and P228 for example) were removed because SIG did not pay renewal fees for guns they did not produce any longer. The P226 and P229 were required to meet the new requirements (LCI and mag disco) because SIG modified them from their original grandfathered form (short extractor). The new requirement is microstamping, and no one is able to do that, thus no Legions or Gen 4 Glocks in CA.Edit: Not the P239, apparently...
