Hi, Some of you will remember a while back, I made an
IWB hybrid holster for my 3" GP100.
Well it's been a year and a half of pretty much daily wear and it's worked out really well, but finally the .06" Kydex body cracked. I may have heated & bent it a little too much.
I would've just made a new plastic shell, but my local gun store had this in the clearance bin, a
Minotaur MTAC, for $25.
SIG P239, Ruger GP100... close enough, right?
The Minotaur holster has different plastic bodies so you can swap them to fit different guns. They don't have one for the GP100, but I had a piece of Kydex that a friend was kind enough to give me, so I thought I'd give that a try. I'm proud of my homemade holster, but the Minotaur's leather piece, and its belt clips and other hardware, are much nicer.
Here’s the GP lined up on the Minotaur leather. (Oh, good, it looks like it’ll fit!

) Note the sight channel form, aka a pencil. Also note the screw posts in the upper right; I’ll need to mark where to drill holes for them in my wooden molding jig.
Boom! Marked.
Everything in place to have Kydex molded over it:
Into the oven...
...for 6 minutes at 350 degrees.
And here is my Kydex press in action:
The Kydex shell now has its basic shape:
Since my last holster project I've acquired a Dremel tool. They’re great for cutting plastic:
When I bought the cutting wheels I wondered why they came in pack of 36. Turns out they're easy to break.
Final trimming, sand the edges smooth, a touch with the heat gun to fine tune the fit, and ta-da!
I've been wearing daily it for a few weeks now, including a steel match and a couple of IDPA matches, and it turned out pretty darn good if I do say so myself.
$85 holster for $25 — life is good.
