Ordered a couple of mags, and figured I'd give the WC checkered frontstrap insert a try, as I wasn't a huge fan of the smooth frontstrap on my ACII. Went on pretty quick, and feels quite secure. I have yet to see how it holds up to actual firing, but even if it doesn't work out I won't be out much. I know actual checkering would be incomparably superior, but I don't have the patience to do it myself, and it just wouldn't be worth having it professionally done on a $450 gun. The shiny black frontstrap doesn't match the matte frame, but again, $450 gun, don't really care, as long as it feels good (and so far it does). Sadly I forgot to add some hex grip screws to my order, and don't really want to pay exactly as much for shipping as the screws themselves cost Wanna kill these ads? We can help!
