Ranger Marlin Ruger

Deal mags cost just under $8 each (I purchased when Sportsman Guide had free shipping)

Tripp followers cost just under $8 each with shipping

Total for each mag around $16.

I bought 4 cheap magazines from The Sportsman Guide that work very well in both my Taurus and my Ruger.  I bought a few more and not one of them would even go into the gun.  I sent them back in exchange for 12 of their stainless steel magazines.  They all worked in both my 1911s, sort of, they did not want to lock the slide back on the last shot.  To fix this I purchased 12 hybrid followers from Tripp Enterprises and they work perfectly in both guns.
