Bob, me too. When ever I have actually had any dealings with HK CS they have done fine by me. They have replaced USC mags that were busted and USP and Mk 23 floor plates that were cracked with no bitching at all. My complaint is that HK knows the .45 mags springs are a problem and have been for at least the 4 years that I have been involved with HK, yet people still keep getting new pistols with mag springs that are shot from the get-go. That seems to me to indicate that HK knows of the problem (they must know because more than a few people have returned their mags to them for spring replacement and HK does it NQA) so why doesn't HK either test the springs to make sure they are up to snuff before building the mags or just dump the entire lot of springs and change vendors? That's the part that bothers me, you should not have to send back a brand new mag to HK for spring replacement. HK knows of the problem but would rather fix the mags after the sale than to prevent defective mags before the sale. Since HK-USA does not make or assemble anything here, the problem lies with HK-Germany (HK-JS) rather than with HK-USA, but it still seems HK-USA should be taking steps to assure that weak mag springs do not enter the market.
