    Good holster, kydex is thin and has alot of sharp edges .
    With some work I made it a decent holster.

    *DIY reply: the Boltaron used in these shells is basically the industry standard .080" thickness. We won't use anything less.

    All Good with a little TLC

    I have bought at least one of each that is offered. They are nice formed and with a little prep on the edges ready to fold and assemble. They can be a bit tight for my taste, so had to add a little heat for some. Would be nice to have an adjustable retention, but for the time it saves if your behind is great. Good Product will continue to buy.

    *DIY reply: stay tuned adjustable retention models are coming soon

    i ordered a test setup for the glock 43 and fitment is great, holster is finished with in 10 minutes! this is a great product to keep holsters on hand ready to ship. perfect filler holster to sell while also making time consuming custom orders. i would love to see more shells available maybe for p320s and 1911s?

    I came across this holster while searching for a replacement for my expensive holster that only lasted 8 months or so and when I realized that this company was offering what looked to be a quality shell made from quality material, I was willing to give it a try especially at the price that couldn’t be beat. The holster came in a few days after ordering and came with a belt clip as well. I reused the Chicago screws from my worn out holster and with a few minutes of carefully molding the shell to fit my firearm it was ready for use. A heat gun on low setting and some careful manipulation of the kydex and this holster fits better than some of my other $50+ holsters. Great purchase, would not hesitate to buy again.
