Uncle Mike's "kydex" (plastic) holster... how hot to reform?

Maybe some rough sandpaper wrapped around the gun will loosen it. As to temp. I think around 300. probably not hair drier but maybe. Its a gamble because its easy to make it too loose or completely wreck it.

Bake at 350, let cool before removing.

TO reform a small area you could use a heat gun, or really hot hair drier.

I use the long BBQ style lighters to warm the piece, but I make a wood mold of the shape I want to reshape to it, warm the Kydex and stick the wood in and let cool, might take a few tries though, but I have made room for thumb safeties and stretched out rigger guard like you want.

Heat gun/hair dryer. About 4-6" from holster. Heat up slow. When barely pliable, insert the handgun and do your thing. Can be done over and over. Get a small hot dish pad and use to shape the area. You will have a minute or two.

1Kperday, just read your post. I do this with Kydex that I make at the shop. Kydex is easily reformed. I have "changed" some areas on other holsters but I cannot speak to the injection molded plastic. Never asked the customer

Uncle Mikes isn't kydex. Mine was nylon. Heat=puddle of goo.

Try sanding it. Make sure it isn't your belt that's the problem. Weak belts can make pistols hard to draw. When youre ready, get a KT, Bravo, or Raven for OWB:

Read this. Guy says he sets a toaster oven to 250F and uses a heat gun.

I use a small toaster oven set to about 250. Just set a piece of scrap kydex on a block, when you see it warp, pull it out and see if it's as flexible as a Kraft Single Am cheese slice. Then make sure the oven shuts off at that moment.

Since decent holsters are $45-60, I no longer make holsters. Except for cellphones, scuba, or tools. It's $10-20 kydex, $15 for plastic loops, $3 in rivets and screws, and 3 hours to get it just right.

Good catch - didn't consider the brand not being made from kydex.

When I said cool before removing, I meant before removing the pistol from the kydex. To loosen kydex, a guy can bulk up the tight area with tape, reform under heat, then let cool in situ, so there is relief when the tape is removed.
