I don't have the one from the Prop Palace, but I have heard lots of bad things about them as a whole. In fact, back in the day (Oh- alllll the way back in MAY!) I ordered one from them- never got it. After almost two months I told them to cancel and refund my money. By then I had one from Biggerkid. I just got the V2.0 one of his- its PERFECT! It fits my Rubies pistols great as well as my Metal Westars.
If you want to save money, go with Rubies. They are good for the price. But if you are going to spend the bigger doe- go with one from Biggerkid.
