Wish there was a 10mm craze.
A couple dozen LEAs do carry and issue 10mm handguns primarily the Glock 20 to their officers.
That's also my winter carry gun. A Glock 20, stock barrel, 24 # Wolff recoil springs and rod, and a hi cap loaded with 175 grain Win Silvertips. 600 fpe in a concealable gun.
Also have conversion barrel in 357 sig and 40SW for the Glock 20 too. Very versatile gun. If the chips were down and a 300 pound crackhead in a heavy parka rushes you, that setup will save your bacon.
Many other caliber will not penetrate deep enough or dump enough energy into the threat. That's why many cops still have shotguns with slugs on board.
No craze. Just talk. But 10mm is a reloaders round. Seen boxes at sproting goods stores for $25. But it still reloads just as cheap as 45 ACP at less than $4 a box for quality compenents and accuracy like no other.
The key is most people talk about 10mm and few actually shoot it.
Get a friend with a 10mm to take you to the range and test various caliber out on old pumpkins from Halloween. 10mm just explodes that puppies.
I have carried most of the below and happily choose 10mm due to its pentration and expansion in almost any conditions. don't HAVE to go through glass but I know 45 ACP has those problems. That's why the FBI carries 40SW.
And the FBI would carry 10mm but too many agents are former professional collegaues of mine and are literally still "afraid" of their guns after graduating from the Academy. So they modified the 10mm case and cut the charges down to get the 40SW.
I'd feel comfortable with 40SW, 357 sig, and 10mm on the street in that order.
9mm and 45 ACP are great competition rounds but are too light and too slow respectively.
So if people are asking for more, that's why 10mm keep scoming up.
It's a REAL smack down go back from whence you came get out of my friggin face and my house and don't come back round. Not that I'm biased or anything
