short comparison from Hornady's website if you wish to cofirm for yourself.
9mm +P 125 gr. FlexLock bullet.
MV/ME = 1110/369
357 Mag. 125 gr. XTP bullet.
MV/ME = 1500/624
357 Mag. 140 gr. XTP bullet.
MV/ME = 1350/566
see not even close.
I guess what I said was taken out of context with no consideration given to chambering the cartridges in firearms of comparable size and weight. So, let me explain:
Glock 17 Gen 4:
4.5" Barrel (5" for me with a factory threaded barrel)
Overall Length: 6.5"
Magazine Capacity: 17 cartridges (18 for me with a flush +1 magazine extension)
Loaded Weight: 32 ounces (36 ounces for me with a SureFire X300)
Cor-Bon 124 gr 9MM +P JHP
MV: ~1250 feet per second
ME: ~435 foot pounds
Ruger GP 100 Stainless:
Overall Length: 8.5"
Cylinder Capacity: 6 cartridges
Unloaded Weight: 36 ounces
Cor-Bon 125 gr .357 Magnum JHP
MV: ~1250 feet per second
ME: ~450 foot pounds
Please note that what I stated in my post did not apply to +P 9MM ammunition, but rather 9MM +P+. I realize that +P+ ammunition is not standardized and some manufacturers make the ammunition hotter than others.
I make my Glock 17 Gen 4 equivalent in weight to the Ruger GP 100 by adding a SureFire X300 weaponlight to the accessory rail and a factory 5" threaded barrel. I use a Brass Stacker +1 magazine enhancement to give each factory Glock magazine a capacity of 18 rounds with no increase in the length of the magazine. I use a 5" factory threaded barrel to make the barrel extended to the point where the X300 weapon light stops at.
So, you can get a Ruger GP 100 and have a weapon that's 4 ounces heavier, unloaded, than a fully loaded Glock 17 Gen 4 with 1/3 the ammunition capacity, equivalent ballistics from simple +P 9MM ammunition (not the potentially more powerful +P+ that I advocated using for carry use), and your Ruger revolver will still be 2" longer than the Glock.
I guess if weight, cost of ammunition, accessory options, and magazine capacity are not considerations, then you can always put a longer barrel on a .357 Magnum revolver and achieve superior ballistics. If we made the length of the two handguns equivalent and gave the Ruger a 1" barrel, the 9MM +P ammunition would give superior performance.
All revolvers are not space or weight efficient in comparison to pistols chambered for cartridges of equivalent power. If there's an exception to this, I'd like someone to point it out to me. The .357 Magnum ammunition is considerably more expensive to practice with than 9MM ammunition is. The Chiappa Rhino is the only .357 Magnum revolver that I know of that's space efficient enough to be comparable to a modern 9MM pistol if length is equivalent between the two handguns. If you purchased a S&W scandium frame revolver, you'd simply have a .357 Magnum revolver that's painful to shoot and difficult to control for fast follow-up shots. Having shot various lightweight .357 Magnum revolvers apart from the Chiappa Rhino, I can say that it is not fun and I will stick with steel frames. The Rhino is the only controllable lightweight .357 Magnum revolver that I know of and it will still be 2 inches longer than the Glock if you want to see a ballistics performance advantage over an equivalently sized Glock using only 9MM +P ammunition.
