Lucky!
I have been pretty lucky in that I have never owned a crappy handgun, but I did own a Browning BP1000 automatic shotgun (I think it was a BP1000, but my rage at this gun has caused memory loss in regards to this truly awful gun) that was horrid in all respects. I noticed that a few of you have had problems with your MkII's, which honestly surprises me. I have had 3 MkII's over the years, two of which were the bull-barrelled "target" models, and one of which I still own, and I have never been anything but completly happy. I recently had some horrible luck with my MkII at the range (FTF, mostly), but thats attributed to a ram-line magazine finally breaking down. I started using my metal mags again, and my problem was solved.
