See also .40 S&W.
Like bell bottoms, these fads come and go.
I see that round looking like a .45 GAP in a few years.
Everybody is trading in those pistols now.
The 40 S@W has been in the market place for well over 25 years with millions of pistols chambered for it and every major manufacturer having many models for this caliber.
More handguns then were ever chambered for the 41 mag and 44 mag 45 long colt.
Hardly a fad more like a major success story that took the market by a storm.
Not going away any time soon for sure
