I shoot blazer with out problem Now as to the Plus P. Their is no Plus P in 380 SAAMI sets the standards for Plus P and they have never bothered with 380. I have shot Corbon JHP and DPX for 9 years from my Thunder It is a hot 380 and works well The Plus P came from Buffalo Bore Seems you say Plus P and more people will buy for Self Defense . I know of at least 1 other company that jumped on the Plus P wagon .
If you want a good SD round then the Corbon DPX should be your choice will do 1050fps and work Worst 380 I have ever tested and others also is the Remington 102 gr 50/50 on expansion and have saw as much as 80fps difference between shoots over clock That is bad quality control.
Critical Defense has also shown some lack of expansion and useless thru walls or glass. Their own writing says for self defense with no barriers In other words face to face
I have shot DPX thru ,dry wall , car door 1/8" lexan, demin , and it always expanded I carry in all my 380's 9mm 45's waiting on 32 at present.
