[Super Demooner ... worth the money ?]

I just got started in ICORE with a new 627 in .38 Super and have already acquired 30 Hearthco Moonclips (new style), 10 Shoot-a-Moon Holders, and now I need a reliable demooner ... Should I buy the Plain one or go for the Super Demooner ... ? Also, any opinions on the Blade-Tech DOH Tech-Lok Holster for ICORE, USPSA, Steel, etc ... ? I don't plan to set the Revolver World on Fire, I just want to have some fun with good, reliable equipment ...

[Model 64 Barrel Swap Questions ......]

I have an older Bill Davis Custom PPC Gun on a S&W Model 64 K-frame and thinking about replacing the 6" PPC Barrel with a 4" barrel for IDPA .... My question(s) are : Will a Full-Lug L-frame Barrel screw onto the K-frame and will a .357 Mag Python Barrel screw onto a K-frame (without major gunsmithing) ?
