I have a S&W M&P compact 40 and a cross breed supertuck deluxe. The holster was made for a Ruger P90. I'd like to reform the kydex but since my firearm is made out of plastic, (zytel), I'm concerned that I might ruin it.
Anyone do something like this? I don't want to take chances with the gun if this is iffy and will just buy another IWB holster.

Heat the kydex without the gun in it, and you'll be fine. Just placing a polymer gun in a 300 degree kydex sheet can't really do much to it; I've done it many, many times without any harm to the gun.

If you're completely re-forming the Kydex you'll want some sort of press. Knifekits.com sells one for $85.00: http://www.knifekits.com/vcom/product_info.php?cPath=41_57&products_id=636 or you can make something similar yourself and use wood clamps to clamp it down.
Use an oven (preferably one your don't use to cook your food (used toaster ovens are regularly available on Craigslist for $10 - $20) or a heat gun to heat the Kydex to about 250 degrees. Place the gun in the holster and clamp down on it with the press for about 10 minutes.
You can heat specific areas of the Kydex with a heat gun and form them with your fingers. I recommend wearing heavy leather gloves to do this.

heat the keydex with a heat gun ( I use the big orange chicago electric one from harbor feight) until it loses its edges and becomes as flexible as a Kraft Singles slice of cheese.
Put the gun in your hot holster, place foam over top, and stand on it. It will take a few trys to get it right. As long as you dont over heat the Kydex you can form it as many times as you want. I have a couple mag holsters that got formed over 10 times until I got the stupid mags to sit straight.
I use the knife kits press. I also stand on it to.
