Do you like the Taiwan 5 round magazines? How many swipes do the factory 5 round magazines require?
I do like the Tawain mags so far. At $11 each they were a good price. They varied in how much filing I needed to do. As above, about 10-15 swipes with a tool file. After every swipe I check it so as not to over due the material being taken off. The mags give me that nice warm feeling as I hear the nice tight click sound as I insert the magazine. The only Mag to fit 100% was the Russian magazine that came with the shotgun.
MDarms Drums needed just a very little file (I used common steel tool file), One swipe.
10rd Promag need just a few strokes more, 2-3 swipes.
The six made in Taiwan 5rd Mags need the most, 10-15 swipes.
