I love my P6! Was a gift from my father - excellent condition, shoots very well. Very concealable little gun! I currently use a Don Hume IWB holster, but I've got a BladeTech UHC on my Christmas list. I've also used the shoulder rig that my particular pistol came with during long car rides. The DH doesn't provide a great deal of retention, but it's comfortable enough and slips into the waistband real quick if I'm going to take the dog out, find myself late to get somewhere, etc etc.
The feed ramp issues were rendered moot after a certain date cutoff. If you wind up with a pre-"fix" feed ramp, it can either be polished, or you can carry a specialty round for self defense. I use Powerball, and have run more than a hundred rounds through with no issues whatsoever. For polishing, I'd check out the SigFourm - IIRC there's a gentleman there who will do the work for you in the $40 range.
The only problem I've ever encountered with my P6 is with the aftermarket "ProMag" magazines I bought for range days - they often fail to feed the last round without some coaxing. If you buy ProMag magazines to go with your P6, do not count on them to save your life. Handy for the range, though. =)
