I bought a Marlin 7 shot mag at the local Gander and thought it would fit my model 25. It does not have the retaining clip on the side. The packaging had said it would fit several discontinued models. I don't have the packaging any longer. If there is anyone here that can use this magazine, PM me your mailing address and it is yours. I'll toss it in a padded mailer and send it to you. One note, only PM me if you have a gun this will fit. I want it to benefit someone who will actually use it. Don't PM me if you just are stockpiling gun parts.
