Hello. I understand this has been debated and run to the ground already, I'm not here interested in raising more complaints. I am interested in fixing a couple of tiny plastic guns in my spare time. If anyone has already done so I'm quite interested in following instructions in how to open these things and installing a small spring. I believe in order to open SW's gun a sticker will have to be replaced since it circles it around at the tip. I could just try and buy the pieces off eBay too. But I'd rather try this myself.
