I would not carry / own it simply because I don't really feel the need to stockpile yet another caliber.
So far, it's...

9mm
12 Ga
.338 Lapua Magnum
6.5 Creedmoor, and...
22 LR, which is more of a "Toy Glock" given it's overall weight and "usefulness". (Translation: Not sure why I bought it?)
(Additional translation: Will be a gift to my oldest nephew as soon as I obtain permission from my sister and BIL.)

This new model by s+w seems to be put into a platform more conducive to concealed carry. The 5.7 was designed to replace the 9mm. That was 1990. 33 years later, it's not only not replaced the 9mm in that time by any police agency in a pistol. The federal agencies nor any local lea I can find carry that caliber in any platform in pistol configuration.

Yeah exactly. I don't believe 9mm is going anywhere in my lifetime, probably several times over.
It is probably the most popular (by numbers produced) than any other caliber?
