Very few folks are listing their carry load for either gun.
I'm sure I'm not the only one interested in what you're loading these guns with.
Fair enough, although over the years I've gradually come over to the mindset that if you have to rely on some specific bullet/load for some caliber, you might be trying too hard to make it into something it's
not.
Then, there's the occasional concern that someone may be trying to rely on some special bullet to offset their lack of skillset.
I'll go first.
In .38 Spl I tend to lean toward any of the better 125/130/135gr loads offered in +P, and yet will sometimes fall back on using one of the better 158gr LSWCHP/LHP +P loads in a pinch.
I have boxes of Win RA38B (PDX1) 130gr +P bonded JHP's; Speer 135gr +P GDHP; and Rem's 125gr +P HPJ/BJHP (Golden Sabre). Even some Win 125gr +P STHP, but those have mostly been used for range quals & practice, as more modern JHP's are available. I prefer the Rem 158gr LHP +P load for its softer swaged lead, and possible better deformation/expansion, but don't lose sleep if forced to use the Win SPD load.
In my M37-2 I've used one or another of a couple of standard pressure 110gr JHP loads, but would still use a good 158gr LSWC standard pressure load, if needed.
Placement, placement, placement, all said & done.
.380 ACP?
Mostly it's been either the Speer 90gr GDHP or the Win 95gr RA380T. Why? Because those are the 2 loads most easily available to me as either issued or easily purchased loads (from a Win LE distributor). I've also tried the Rem 102gr GS (when it appeared in the training inventory for a brief time), as well as the standard Win 85gr STHP (for the same reason).
Again, I worry
less about the specific modern load, and
more about it actually running in the gun (LCP, for me), and doing so while I've effectively running the gun to make rapid, accurate hits in a controllable manner.
I like the heavier bullets in the .38 loads, for bullet mass & momentum, but the lighter .380 loads aren't a compromise that causes me too much loss of sleep when I'm able to use the slimmer & lighter LCP at times.
Neither the snub .38 Spl nor the .380 ACP are what I'd carry as a primary plainclothes weapon (aside from being a secondary weapon). For off-duty & retirement CCW? Mostly not a problem. Nice options for low risk assessment situations and conditions.
No, I don't have a crystal ball, but more than 3 decades of carrying a weapon with a badge has given me some experience and confidence in choosing something to meet my expected needs, and being able to assess those needs.
I certainly don't denigrate the choices of some folks to carry larger & heavier concealed weapons, though. Just like I don't care how they feel about my choices.
