I had an Uncle Mike's kydex IWB holster laying around I bought last year and didn't like. I was getting ready to put it on the EE when I decided to try a little project. Total cost was $0, since I already had the holster and assorted nuts & bolts in the garage.
First I removed the belt keepers which were screwed onto the holster itself. Then I positioned the holster where it felt most comfortable and marked the spots where the screw-holes were on the center console of the car. I drilled two holes and then screwed in two short screws. I had to flex the holster significantly to get the screwdriver in the correct position, but in a few minutes I was done.
Once I slid the weapon in for the first time, I noticed two problems.
1) I couldn't comfortably get the fingers of my right hand between the pistol and the console. The space was simply too narrow.
2) The rear sight and back of the frame hit the underside of the dash when I drew the pistol.
Neither of these problems completely prevented me from drawing, but they took time to get around. So, I removed the holster again and drilled a third hole, rotating the holster down to avoid the underside of the dash. I also mounted a pair of 1/4" nuts on the screws between the holster and the console, giving me a wider corridor to slide my hand around the pistol grip. Finally, I removed one of the adjustment screws on the bottom of the holster and drilled a long drywall screw through into the console instead. This pushed the bottom of the holster towards the console, further widening the space up top for my hand. You can see the white drywall screw in the top picture.
This pic shows the two nuts acting as spacers, and the drywall screw which helps angle the top of the holster away from the console.
The whole project took less than an hour and I am one of those guys who barely knows a hammer from a screwdriver. A few test draws left me very comfortable that I can draw much more quickly from the driver's seat with this holster than from my hip holster, or the center console compartment I've been using up until now.
It isn't pretty, but I am happy with the way this turned out.
