A while back I asked for seat bolt specs for the driver's side front bolts but didn't get any responses. The answer was M8x1.25. I've been working on a driver's side holster that either does not require drilling or is supported by the tub. I'm not opposed to drilling but I'd rather not if possible. After pulling the center console I came to the conclusion that attaching a holster to the plastic next to the transfer case shifter doesn't provide enough support for a loaded handgun bouncing down a rough dirt road. Ram Mounts happens to make a series of 1" ball mounts with a M8 center bolt so I replaced the seat bolt and ordered a 6" Ram Mount arm. The holster is a hard mount Dara custom kydex holster for a G20 and TLR1 light with 1" Ram Mount. You can move the holster around as well as change the arm to a different length if required for seating position. The mount is very solid.
I haven't done any drills yet but can already tell this is faster than drawing from a belt holster. Drawing doesn't require leaning over or moving from the relaxed seated position. The pistol is slightly below the seat and does not contact my legs. I can draw without sweeping my extremities or the passenger.
Here is the 1" ball attached to the seat frame:
Here is the mount adjusted with the seat moved rearward:
With the seat adjusted, does not contact the console or seat:
