I never trusted the 40 myself, again in my own opinion. Back in the 90's with all of the 40 craze going on, most guys wanted the new "super" round as it was kind of marketed to be. Re- member back in the 80's with all of the wonder nines coming out, and people were all caught up in the 9mm. Then the 40 turned up. A friend who had gun shop and range remarked to me after I asked his opinion of the 40, that he says it was ok but could turn out to be a problem as since he worked on guns, he was Leary that the 40 was being cranked out pretty fast by a lot of companies and they were at the time basically using a gun that was designed for the 9mm to now fire the 40. Remember the Browning Hi Power 40? That wasn't out too long before they had to beef it up to handle the stress. Also back then, a buddy of mine was a Chief in a next door city, and he would always laugh at me when I would say to stick with the 9mm......well he is retired now,, but his department and most others for that matter have gone back to the 9mm. Especially after the FBI went back to the 9mm, because it's a popular given that most want to follow the FBI......Yes. It has been said the the FBI also had more women hires now etc., But to me, with the improvements in the ballistics, and the basic cost factor of not only the ammo, but in the life expectancy of the firearms themselves and their reliability......Reliability is everything, IMHO.
