That makes sense.

I'm eating nothing but triple cheeseburgers, everytime, all the time....

Less wear on the gun, less component cost, familiarity with the same gun, power on reserve aren't bad things.

Makes more sense to some people (who aren't handgun junkies) to cover a lot of ground with one gun.

Besides, everyone knows there are few reasons to shoot nothing but full power 44 loads. Getting jacketed hollowpoints to work right, shooting very large animals, long range, silhouette, or just because you want to all come to mind.

Some guys simply want to brag/argue about how they have a handgun for every 100 fps. and 10 grs. of bullet...Go figure.
