you know the 35-40 dollar range is normal for most mid to upper level guns.
My sig pro 2022 mags are 39 plus shipping
my magnum research eagle 40 bucks for one, if you are at a gun show you can get two for 70 if the guy wants to deal.
but again 35 each
so that is pretty much in line with most of the other mid price range pistols I'm familiar with personally
