As the title says it seems that, in order to fit my 30 round promag and 20 round tapco mags that I will have to file down the tang at the back by the trigger group. I bought the tapco mag when I bought the gun a couple months ago and it didn't fit well with the wood stock, but didn't worrie to much since I had an archangle on order. I tried to install them today and both mags have the same problem and seem to tight. Have I forgotten to remove something? Or has anyone els had this problem before?
