All right folks, I'll just say that to me the meaning "great customer service" is somewhat dual. It can mean either greatly written policy to protect and accomodate customers or, in case if it's not, a pure luck of getting a nice person on the phone who's willing to make one extra step and satisfy one's needs.
In both cases, however, the opposite is true just as well. Despite a good policy, one can always run into an irritated rep who's...well, we've all been there more or less. Or, a good and understanding rep may be highly restricted by his/her company's rules.
My experience, in fact, is a combination of both.
1. Steyr Mannlicher-- they'll send you gun FOR FREE and reimburse your own shipping costs in case if your pistol as little as simply mulfunctions (Glock, Inc., on the other hand, charges over $200 for KB!ed guns!). I've been told "Well, you shouldn't be left with an unreliable pistol..." In their case, it's both great policy AND great folks who work there.
2. Kahr -- extremely curteous and supportive, but customer service policy is not on par with that of Steyr Mannlicher (you must admit it's hard to beat
). I was, nevertheless, extremely pleased with their service; one of the technical guys there (gunsmith?) ran everything on a very personal level, and we spoke for almost 30 min. on the phone.
3. SIG Sauer -- very nice people (my experience) although with high demand for these fantastic weapons, the company policy on customer support could be a bit more accomodating.
4. S&W -- a good combination of both. It's been a while though, and I simply don't remember all the details.
I know quite a few experiences with Glock from many other people but never dealt with this company directly myself. Thus, except for the aforementioned fact above, I won't say anything.
