I'm also leary about buying stuff like this on eBay or Etsy - I did find someone on Esty that makes great metal parts though "QuestDesignCanada". I got his Metal Darts for my RoTJ Boba Maker Gauntlets - Now I just need the Gauntlets (According to BM, They've been shipped and are on the way). And I plan on getting his Gauntlet Rocket too.
Thanks! Glad you like them! I am on here too! And yeah, i will replace the belt (not ammo pouches) should anything happen to it, including weight gain. They are 100% vinyl i make them custom to each wearer.
Here's something i'll be making available by next week!
