to copy a previous post of mine, but this would still be my answer:
I have purchased a very large variety of handguns over the last several years. Lots of HK's, some Sig's, Glock's, Walthers, etc...
From Sig, i purchased two of the P220 Carry models right before they decided that the external extractor design was better, and I had to send BOTH of them back to Sig for repairs due to horrible feeding performance. it was a known issue for Sig and I have no idea if it has gotten any better because i am uncomfortable buying any more of them.
From Glock, I really liked the texture on the Gen 4 grips, and purchased 4 of their guns, only to find that Glock had known issues with their models after the Gen 4 was released and ALL four of mine have been sent back for their fixes. Feeding is fine, but extraction is so weak i could catch the brass in a pouch hanging on my right side if i wanted to, else it would hit me in my face. Who wants a gun to SLAP YOU IN YOUR FACE???
I have two Walther PPQ's, a regular one and one of the badgered up "First Editions"... The regular PPQ that i got has a very uneven and blotchy finish. the worst looking finish i have ever seen on a factory gun from any brand. It shoots fine, and I will keep it, but you can count me as an "unsatisfied" customer as both of the Walther PPQ's that I received had "issues" that Walther and S&W were aware of, and they sold them to me anyway. edit (I have purchased 2 more and they have been perfect from the get go)
In each of these cases, i have felt somewhat "screwed" as the consumer, and not because i was being "picky", but because the product was so obviously sub-par, and in each of these cases, i was buying guns that were more or less intended for ME to be the consumer, i.e. they target the American civilian, and don't just produce guns to just throw at military and police contracts.
In each case, the Customer Service was supposed to be good, or at least better than the Internet says that HK's customer service is. So far, I would rate my frustration with Walther and the PPQ (selling me one gun with aweful finish, and selling me another one with a damaged slide) as worse than with Glock or Sig, and I have high frustration with them as well. As for Walther, i am not sure how good their CS is, because i dont get to deal with them. If you need CS on your Walther PPQ, you have to deal with S&W, and THOSE are the guys who damaged my slide (and the slide of all 6 First Editions i have now seen in person as well as dozens of others) while installing the night sights incorrectly. There just isn't anything i can do about it, and so i will be selling it off. I purchased the "First Edition" as a collector, and it is crap, doesn't even feel like S&W or Walther care about these issues or had tried to make sure their product met their standards.
I have even purchased two special order Nighthawks that both had to go back to the shop for repairs, one was delivered to me with the grip safety not functioning (gun would fire without it depressed), that is flat out unforgivable.
Enter HK. The company that isn't supposed to care about ME or my experience. Yet they are the ONLY firearms manufacturer who has always produced a perfect product for me each and every time i have purchased one. And their CS department has been FAR superior to my experiences with the others. (Sig tried to say that I was making up the issues, Glock said i wasn't using good ammo, and Walther said the damage was a "burr" and to find a pistol smith to fix it). I have never NEEDED HK CS to solve "issues" with their guns. but i did convert one to LEM once and sent a few more in for them to install the Night Sights. in every case, communication was spectacular and the gun was back in my hands on the THIRD day from when i shipped it to them. The LEM install was done the same day they received the gun and the armorer called me on my cell to let me know he was getting started.
I love HK, their guns, AND especially their dedication and commitment to quality and excellence. They may not target ME as their consumer, but they are the only company out there who seem to be making products that represent what their reputation has earned them. HK appears to take pride in what they do, and what they produce. I think that sort of thing has been lost in many other manufacturers lately.
For these reasons, I would happily encourage anyone to spend their hard earned dollars on an HK. You simply will not be disappointed in what you get.
