Well its listed as 380 Plus P as is a couple of other manufactures, which is not really true.
There is no Plus P pressure rating for the 380 so it can't be plus P.
what it appears to be is a 380 loading that is very,very near the top presuure rating that is safe for the 380 cartridge.
This is designed for modern strong locked breech 380's, which the TCP 738 is, there are so many 380 pistols over the years that are not good qulaity that it certainly might not be safe in those however.
I personally do not use it or corbins ammo as there have been several reports of guns being damaged by these ammunitions.
now i do not nor have i seen this its simply reports on the web and different forums.
A 38 super site that i visit at times noted in an ammunition test of several companies that both Buffalo and corbin showed extreme signs of pressure in the 38 super, so thats enough for me to stay away.
its a decision that you must make as its your gun.
To me I had rather use a standard pressure round that i know will work all 6-7 shots than to have a magic super power round that may disentergrate of malfunction the weapon on the first shot.
In the end it may be best if you are not comfortable with the power of the 380 to simply move to a 9MM, its got twice the energy of the 380.
