I recently found a company that has factory 3.5 lbs connectors and other parts for very good prices. I wanted to share this info for those of you that may need factory parts. He sells the factory 3.5 connector for $11.99 shipped, just register on Glocktalk and let him know you are a member. The address and website is:

I don't think you can order from the site but I think he answers his phone late. In my opinion he ships very fast and is a pleasure to do business with.
