I've been looking for low-profile slide release levers for my H&K P2000. They are readily available at an online specialty store that shall remain nameless. The price is almost $80, plus shipping. That seems incredibly high.
So I called HK USA, and was informed they were out of stock. Then the CS rep went online and checked the same online specialty retailer that I had previously checked. He almost choked when he saw the price. Long story short, he "found' a set of the levers within HK's inventory and sold them to me for $23, plus shipping.
I know HK has a tarnished reputation for customer service. But I'm just some dude, just a random customer, and HK took really good care of me. I'm impressed.
