I'm still struggling with this issue as well and as SeattleMike mentioned, our other thread on this hasn't come up with a solid answer. I sent Console Vault an e-mail today asking if the 5th Gen 4R was being considered for their product - I'd like to get one of those.
I have made the false bottom for my console as someone in the "better SAFE than sorry" thread mentioned, but alas, my G23 doesn't fit as I'd hoped.
Still considering a square lock box under the rear seat, but was hoping someone had a model that was tested and approved before I spent money on trial and error.
I have a question about cutting the inside of the existing console to make the G23 fit, but i probably need to attach pictures to best explain. The short of it is, what is under the raised portion of the bucket portion of the console - say right under where the coin holder is (side opposite the 120v plug)? I was thinking of cutting a hole so that the barrel of the G23 could stick out a 1/2", allowing the item to completely fit below the false bottom. If that question makes sense without pictures, I'd love an answer or a link to pictures of the console disassembled (the diagrams aren't clear to me). I'll find some pics and update so this makes more sense in a bit.
Thanks!
