I recently picked up a Kel-Tec PF-9 to conceal-carry, mostly for in the truck. I've been trying to find a good place to keep the gun that a) is out of 'plain sight' (per Texas laws) and b) I can get to in a single motion without my hands being seen by a would-be carjacker. These criteria eliminate a number of places (console, glove box, door pocket, etc) as they either require too much time to access, or can be seen through one of the windows.
Looking at my pistol, I realized it was smaller than the coin tray in height and width and just might fit with some modding. I took to the coin tray with a razor blade (wish I had a dremel for this part) and by removing a bit of plastic from the tray and a bit from the dash, I was able to get it to fit with no visible changes from the cab. Note, if the gun was any thicker, I don't think this would work, so I'm guessing the sub compact Glocks, etc won't work in this position. The Kel-Tec is one of the smallest 9mm semi-autos out there, so no promises that this will work with bigger guns. The .380 subcompact crowd shouldn't have a problem though. Ok, without further ado, here's the pictures:
1) Trim plastic from the coin tray to fit your pistol:
2) Trim A bit of plastic from the bottom of the opening in the dash:
3) Put the coin tray back in and test fit
4) All done
