Fellow seemed very put out to have to talk to me and take my order. "Did you try our parts website, HKParts.net?". Umm, yes I did, the parts are not listed there. He did not even want to talk about the larger HK45C mag release lever, just told me "out of stock". Then he informs that I have to pay an extra shipping fee on orders under $50. All I wanted/ordered was 2 little springs. Shipping is more than the parts cost. S&W and Ruger have sent me small parts gratis numerous times. And I thought Glock CS was bad. On the plus side, I didn't have to give him part numbers. As soon as I told him was converting to light LEM, he knew what springs I wanted. I'm thinking my next new gun purchase will be an M&P 40, certainly no more HK's Wanna kill these ads? We can help!
