.380 itself is disappointing lol.
Been there done that, its why my secondary is a .38 snub.
I don't have the ability to test the ammo for anything other then shooting it into milk jugs, but it runs well in my Rami which is a short barrel gun like the Shield is.
Here's a youtube vid of the 9mm 115gr version from G26:
I figure that at 25gr heavier the .40 load from a short barrel isn't going to be too bad.
I like it especially for my Rami, because it is running less velocity and is on the lower end of weight for .40, and it is noticeably faster on follow up shots.
That being said- I still prefer the heavier projectiles and in the extended MegGar mags I have for my CZ (14 rounders) I stoke it with 165gr or more.
But when you've got a really small gun with an abbreviated grip as in the 8 round mags that came with the Rami (even with the pinkie extensions lol), it doesn't hurt to tame the snap of the .40.
I think this is a very good load for short barrel .40's.
YMMV.
