The base pads have changed from a round retaining plug to a square retaining plug. I received a mix of different base pad attachments, which makes attaching aftermarket base pads problematic.
Great mags, but MecGar has apparently changed their base pad designs to a square retaining plug, from a round retaining plug. I received a mix of different base pad attachments, which makes attaching aftermarket base pads problematic. The Volker base pads don't work with the square retaining plugs. The markings on the magazines are also different, but that of course doesn't affect function.
