Just thought I'd like you Mini-30 owner that Ruger's Mini-20 20 Rd Mags actually work, unlike most aftermart mags. I have an older (but mint) Mini-30 and pretty much given up using aftermart larger cap. mags. Until I saw Ruger was offering 20 rd mag, so I said what the heck I'll give'm a try and they worked great. And to think I was ready to get get of that rifle.
