Having read FBI ballistics test reports, I can assure you that this is a “mine is more effective” comment.
The conclusions of the report very simply put:
In terms of incapacitation, Handgun rounds are generally inferior to rifle ammunition.
The 9mm was identified as being particularly ineffective.
The .45 and the .357 were determined to be the most effective SD handgun cartridges. (The study predated 10mm and .40 S&W)
I owned a S&W 5906 and traded it in on the Kimber.
Old data. Come over to my house and I'll put 16 rounds in a 3" circle at 7 yards in under five seconds.
To each his own. I can afford .45 acp weapons. I just don't like the caliber. Is everyone supposed to like .45 acp?
These caliber wars are stooopid.
The Navy SEALS don't seem to have problems with 9mm. But I guess you're more experienced than they.
The Kimber owners I know dumped them and went with Sigs and Colts.
