.38 Spl is certainly effective, but a 9mm does have a bit more “oomph.” Now, a .38+P is another story. Out of a snubbie a .357 magnum has pretty much the same ballistics as a .38+P (in order for the .357 to rise to its full potential it needs at least a 4” barrel).
I have .38, .38+P. .357 magnum, and 9mm. I do not feel under-gunned with any of them.
Although I shoot a LOT of 9mm,I never have had much respect for the caliber.It’s great for plinking,but I’ll fall back on my .357 or .45 pistols for life and death .Or better yet my 12 gauge or MP5.
