Looks like they're out of stock right now but this will save you a lot of trouble.

so with the couple of views of funnels, that are not in stock, i drilled some pilot holes and used a piloted 1/2" counter bore to remove material in steps, and then used a hand hispeed grinder to blend it all. now have a functioning drop port. cosmetic and clean up work needed.
thanks

I match the port the best you can, Some you cant go all the way or you cut into the trigger gaurd. Two reasons. I have seen cases wedge in a funnel shape. And if you ever drop a case ass first down the port and it gets stuck you want to be able to fit your finger in the port to push it back up quickly.
