A five shot cylinder is NOT a serious shortcoming...!
Howdy,
The 44 SPL, in any guise, cannot be considered by anyone to have any shortcomings. A 5 shot cylinder isn't a hinderance in a weapon which must be both 1) concealable and 2) effective.
Since most engagements where a snubby would be employed are typically spitting distances, even hipshooting will generate hits with this type of gun. Taking the time to line up the rudimentary sights will easily generate 'minute of felon' accuracy.
The 44 Spl, with proper bullets, will cut a .44 caliber hole which is VERY effective at bleeding out a 'target', better than any 9mm, 40 S&W, or 45ACP with traditional hardball ammo. The characteristics of hollow point ammo increases the effectiveness of all ammo, so you must consider that the 44 will not loose anything against the others with this type of ammo.
By shooting at center mass on your target, you cannot go wrong with a 44 SPL. Should you need more than one shot to completely incapacitate your opponent, a double-tap is always recommended in situations such as these.
Usually, the first shot does the job, the second is just for insurance. This leaves 3 shots for any 'others' who haven't figured out that you mean business, and wish to be left alone.
Just the plain fact that you've shown that you are armed and willing to defend yourself should be deterrent against any more unpleasantness. If the snubby goes 'BANG-BANG!', you remove any doubt about it.
Good luck!
