The 9mm you posted shows a capacity of 7+1.
What that means is 7 round mag, and 1 in the pipe (chambered).
CCW = concealed carry weapon
Home protection means (IMO) the ultimate attack. Your safe place is being threatened.
You’re not in public for some random event. You’re not getting attacked by random drunk guy in the bar (which of course you don’t carry a firearm into anyways.)…
Home defense = last stand.
Last stand means you may need maximum available force.
Maximum stopping power (to many) means .45
(look up ballistics gel tests to see the difference between a 45 and a 9mm.)
I prefer more rounds, in case it’s more than one person attacking. But a 45 packs quite a punch.
Oh! And JHP = jacketed hollow point.
As opposed to FMJ (full metal jacket)
