I'm a really big fan of both Glock and HK. I have the HK P2000 and the HK P7M8. I also own the Glock 36, 19, and 26. I truly love both brands. I started off with the Glock 36 as my very first handgun, and even though it only has six round capacity (stock) it feels great in the hand. I have had no problems with any of them. The Glock 36 had a couple of FTE problems after I shot about 2500 rounds through it. I replaced the recoil spring (provided free from Glock) and haven't had a problem since. If I had replaced it sooner like I was supposed to of, then it wouldn't have happened.
I personally carry the HK P7M8. It is a very safe, simple, genious design that allows me to always keep it loaded while I carry. It also allows for very quick follow shots. A little on the expensive side for a 9mm but I believe it to be worth every penny. Try gunbroker.com for a good deal on one. You can't go wrong with either brand. Glocks are cheaper...9mm are cheaper. That's all I can really say, except i'll take a 45 over a 9mm any day. Good luck.
Life is just full of hard decisions...I really feel sorry for you.
