Man, I -really- need just a single one of those single stack PC marked 4506 mags to mate up with my 845 Limited.
Mine is the slightly less attractive (but more scarce) second run Model of 1998. I got mine used with zero of the original box & etc. So I cannot say definitively whether the second run 845 originally came with those magazines. However, I can say that the first run 845 Limited from Lew Horton did indeed.
Sure would like to swap you something for just a single one of those.
