I can't argue against a G36, owning one myself. However, I would suggest you factor in a few other considerations.
1) Maybe we're talking semantics here, but in your first sentence you call your choice "an HD pistol" - generally, "HD" denotes "home defense". However, in your explanatory points, you go on to describe the characteristics of a concealed carry weapon; sometimes called a "CCW". There are HUGE distinctions between a weapon meant for HD and a weapon meant for CCW. An HD weapon should be chosen less for size, weight and capacity, and more for firepower and ancillary attachments (e.g.: weaponlights, laser sights).
2) As stated, I own a G36 along with several other Glocks. I bought my G36 from a co-worker who simply couldn't get it to shoot reliably for him, yet I had no problems with it. We compared our shooting stances, and we decided his style caused sufficient elbow flexing as to almost replicate limp-wristing. The G36 does not like to be limp-wristed. I would suggest you attempt to borrow or rent one and put about 100 rounds through it to make sure it will be 100% reliable for you.
3) How well-trained and experienced are you with a Glock, and how much are you willing to train? I love Glocks and feel perfectly comfortable carrying one concealed. However, IMO, the Glock is the most dangerous CCW weapon there is for the uninitiated. That 5.5 pound, 3/8" trigger pull is the only "safety" you've got. If you screw up the manual of arms, particularly during re-holstering, you can put a .45 caliber hole in your lower extremities.
4) Who else besides yourself will have access to it? If you are going to give it double-duty and also have it standing by as an HD weapon, all the considerations in point #3 apply equally to anyone else who may have access to it.
Bottom line: if you want a great concealed carry weapon with small but adequate capacity and .45 ACP power, a G36 is hard to beat. But you really, really need to know what you're doing.
