I made a short day trip to visit a friend yesterday and we did our normal gun shop run plus lunch after. I scored these two for a song. I've got other examples of both models and a ton of Sig mags, but only a couple P5 mags and need to find more. Seems they're MIA these days.
and bonus, the P5 was threaded 1/2-28. Such a good job, it looks factory but of course is not. Same date code as my other example.
