Pathfinder,
All current 20 round Ruger mags were diverted from law enforcement distrubutors. Tha't why they are so high. Ruger hasn't seen fit to crank up production and sell them to the general public until now. Remember Old Man Ruger's support for the 10 round mag limit, don'tcha?
I did not know any of that - ex-wife wouldn't allow any guns and I lived close to Chicago - I'm fairly late to the game and have missed a lot of the history. Thanks for the knowledge.
PS: I just bought my first big safe cuz I outgrew the two smaller ones I had, so I am making up for lost time. Let's see, a 1911 will go there, the 6.8 AR I'm building will go there, and where in the heck will I put the Masada?

? Oh yeah, next to the Sig 556 . . . .
