I made a Kydex press that is really better suited for a Pancake holster than a Taco style but I think it should work for both. I'm using .080 Kydex.
Foam held in place with Velcro:
I made this stand to preheat the gun if needed. I believe it will help retain heat to obtain high definition during the molding process:
I prefer the 2 screw clips from FOMI - wider and more stable - than a single screw design. They should hold better on the belt.
Spacers and sight tunnel.
The sight tunnel is created by the piece of yard-art plastic tubing with the ends modified to fit the front and rear sights. This worked pretty good but I believe in the future I'll let this piece extend a bit beyond the front and rear site to maintain a better straight line.
The wood piece under the trigger is about 1/8" thick - just enough to allow for a rubber spacer for retention adjustment if needed.
I don't want to do any cutting until I verify the couple of areas that need improvement - sight channel and clip mounting.
The right side of the gun (not shown) has 2 rubber faucet washers taped to create space for nuts where the FOMI 2-screw clip (common for IWB holsters) will attach. I have these slopping the wrong way. It would place the gun at negative cant so this will need repair/modification.
Results:
Right side:
Left side:
I believe this style can be used for inside or outside carry (providing they do NOT have a body shield on either side) by moving the clip to the right or left side. I'd like to see someone put the dimples and holes on both sides for this flexibility. I may do that if I can find a good clean way to add space for the t-nuts inside.
I also think this could be made "Tuckable" by a simple 3" deep U shaped piece the same width as the clip between the clip and holster.
I liked what I have seen from Overwatch/Treadstone Holsters (PastureOfMuppets) in what he is doing. Very high quality holsters.
