This product is one we get a lot of request for. Here's the problem: The factory blued steel drift pins (B-35 magazine release and the ejector) fall out of the trigger housing because they are held in place only by gravity and some friction. The solution: Hornet Custom oversize stainless steel drift pins fit tighter and thus hold their position better. Rust resistant and gives smoother action. Keep a spare set in your tool kit in case you lose these critical parts in the field. Set of two.
