Anybody offer these..?? I think Pearce and one or two others have extended plugs for Gen 3 and earlier, but I haven't seen any for Gen 4, so far the only ones I've come across for Gen 4 just plug the hole with a flush fit, but they don't extend below the frame. Specifically I'm looking for extended plugs for my Gen 4 G23 and G30. Any info is appreciated thanks
