I have to disagree with the masses...I LOVE my HK's (including my HK45). You won't see me trading it for a 1911 any time soon, and I like 1911's, just not for the job of an everyday chips are down weapon. Not saying they can't handle it but if you're carrying why not get the one that weighs less, recoils less, and carries more while being ultra reliable??
HK Cust service...call me a fanboy but I've met alot more folks that have "heard" HK customer service is bad than have experienced it. I've dealt with them on some upgrades and they were nothing but excellent to deal with...
