34. I highly doubt that.

Most gun nuts that I know (and I know quite a few) have far more rifles than handguns, which makes complete sense if you understand firearms and their uses. Handguns are generally a weapon of last resort, and are near universally employed against humans, so there's not very much cause to have multiple varieties of handgun, except to a collector.

Rifles, on the other hand, are employed against a very wide variety of targets, and naturally, a rifle well suited to hunting bears or mountain lions, for example, is probably not going to be very suitable for hunting rats or other small pests. There are LOTS of gun owners who, like me, have owned numerous long guns, but have never owned a handgun, simply because they are not very suitable to the things for which we actually use firearms.

You are most certainly correct to identify the unique threat posed by handguns, and I'd agree with you whole-heartedly on them being more strongly regulated, but I think your assessment that the majority of firearms in the US are handguns is badly mistaken.
