The SA magazines are 13rnds since they are based on the Hipower, and the DA are 14 just like the early M59 mags they are copies of.I've heard the exact same thing about the PJK's and P9M's in regards to the trigger pin and the magazines. One of the models has a different barrel lug as well than the standard HP lug. I believe it's the later model, but I can't remember for sure, I think it's the PJK. I did examine a PJK magazine up close once and did notice the exterior was a bit rough and this was a new gun. But the finish on the gun looked nice. I don't remember how the spring was as it was a long time ago. IIRC the magazines were advertised as 14rd, but more likely I would say they should be loaded with 13rd like the original HP magazines with the solid follower. Though I don't have a PJK/P9M magazine spring to count the coils on, I don't think the followers are hollow like the 15rd Mec-Gar version where the spring sits up and inside the follower for more room against compression.
They are not interchangeable......
