bigfatdave I was talking about David E's snarky comments of "anyone can do it"
You know what, I was wrong ... sorry about that.
I might have been fed up with the endless redundant threads (which this is not one of, really) and some truly difficult to read crap postings. Not really an excuse, just too much general annoyance added to what appeared to be an attempted slam in return for polite conversation.
Firefox is an all-around better web browser and has built-in spell-check, that's the best helpful suggestion for that subject I can offer.
If you're going to make your own, I think the biggest challenge would be the cutting steps, I think a bandsaw is the method used by people with a full workshop.
Other than that, you'd need "chicago screws" and/or rivets, belt clips and/or loops, and a heat gun or heavy-duty hairdryer.
I've never made Kydex goodies from scratch, but I've modified a few pieces with the wife's hairdryer set to the highest setting, then gentle re-shaping with a light leather glove on the hand or using a wooden dowel.
Try dropping an EMail to CrossBreed and KHolster as well, they've both responded to me within hours in the past.
I can take and post some pictures of my rigs if you like, for something to imitate, I have an all-kydex rig for some mouseguns and a CZ52 as well as CrossBreed SuperTucks for 1911 and Walther PPS ... nothing with a light though.
If I were setting up for a holstered handgun with light, I'd still make the holster grab the ejection port/trigger-guard/pistol's shape, leaving it useful for the same gun without light or a smaller light if you change up in the future ... in fact the KT P32 holster I actually use was built with room for a laser I don't have/want, it works fine with the gap.
