Yep, I get it. If only they weren't so damned expensive and near impossible to find around here, even in post-ban 10-round.

Pre-ban Ruger OEM 20's and 30's? Good luck with that!

I paid a king's ransom for the two pre-ban 20's I was able to obtain... but that source is now out for good.
I'm going to see what happens at Saturday's show. I see three possibilities:
1) No one will have anything in a Ruger Mini-14 magazine at any price other than maybe some new post-ban 5-rounders.
2) There will be a few random pre-bans with incredible "sky-high" prices on them just like on that certain gun auction website. Someone will jump on them (but not me!).
3)
It's always possible (unlikely, but possible) that some dealer has managed to come up with a batch of pre-bans and is willing to sell them at something slightly less than a King's ransom. If so, I'll be interested.
Chances are that I will come home from the show empty-handed... in which case I will turn to the Interwebs. Can't afford enough in genuine Ruger 10-rounders... so I may still be tempted to try a Pro-Mag or two and see how they run.
