Well, it's certainly not uncommon to see some folks get all worked up over what
other people may choose to lawfully carry for a dedicated defensive weapon.
While I've not made it my business to denigrate what other LE choose to carry for off-duty weapons (as long as it's within policy), or what non-LE folks choose to use for lawful CCW application, I've had my own thoughts on the matter over the years.
Until recently, the last .380 I'd briefly owned and carried was about 25 years ago, and that was a Beretta M84. Large for the caliber, thick (dbl stack mag) ... and nowadays I have 9's about as small, or smaller.
A while back a good friend of mine (another instructor) sheepishly admitted that he'd bought a LCP and had been using and carrying it. He loaned it to me, and I was pleasantly surprised by how well it could be slipped into some of the tighter jeans pockets (pocket holstered) in which I couldn't slip one of my J's.
Realizing the inherent capabilities of the .380 cartridge, as well as its practical & potential limitations, I decided the LCP could be used to fill a role. I ordered one of my own.
I test-fired mine using 3 types of hollowpoints. I tried a 25-rd box of the Remington 102gr BJHP (Golden Sabre), a 50-rd box of Speer 90gr GDHP and half of a 50-rd box of the Winchester 95gr RA380T (T-Series).
Although the rudimentary front sight is small and hard to see, especially in reduced light conditions, the little LCP was surprisingly (amazingly) accurate when using aimed fire. As long as I could see the sights, it produced very tight cloverleaf groups at 5-7 yards, and respectable groupings out to twice as far. Good enough for my intended purpose. Indexed groups were also respectable at reasonably close distances.
Due to availability, I'll probably use either the Speer or Winchester loads.
While I'd prefer to carry one of my compact/subcompact pistols, or one of my handful of J's, there are many times when I either don't feel like belting on a larger weapon, or I'm not able to pocket-holster carry one of my larger pistols or revolvers. The LCP will fill that role, and I'll work to maintain my skillset with it and continue to qualify with it.
Never thought I'd own another .380, though.
Never say never.
Granted, it's not what I'd want as a primary weapon if I were still being dispatched to continual calls-for-service, or managing a caseload where I was continually putting myself into stressful situations involving persons who might be armed, and who might be involved in criminal activities.
I'm retired, though, and I have much more control over where my daily interests and activities take me.
Doesn't mean I won't be carrying one of my larger J's upon occasion, or one of my assorted 9's, .40's or .45's, though. Just depends.
It's just that now I have an option to still be able to carry a weapon in circumstances where I otherwise might have decided not to carry one.
