Ljutic:
I am one who strives accuracy, but you have caught an embarrassing mistatement in my original post when I referred to the Winchester Ranger T .380 Automatic ammunition as "+P." I should have used instead the term "Law Enforcement." According to my understanding, there is no SAAMI standard for +P in .380 Automatic, and SAAMI specifications rate the .380 at approximately 950 fps velocity and 200 foot-pounds (ft-lbs) energy for JHP bullets.
Winchester rates its Ranger T Law Enforcement 95-grain .380 as providing 1,000 fps muzzle velocity (length of barrel not reported but assumed to be 4"):

Mea maxima culpa, and thank you for pointing out my erroneous use of the +P term. The ammunition I was describing is the same one you tested, Winchester Ranger Law Enforcement .380 Automatic 95-gr. T-Series, Product No. RA380T.
In closing, I notice that your test of the Ranger T Law Enforcement .380 showed 896 fps from the 2.53" barrel of a Kahr P380 with 10.5" of ballistic gel penetration:

And believe me, I have an open mind on this subject.
Thanks again for catching my misstatement and giving me the chance to correct the record. Also, thanks for the compliment on the "blinger." It was my EDC before the R9 came along.
