Erich:
Thank you for your very good information and advice on the .380 ACP. I had been carrying the Golden Saber in my P3AT, but upon reading your advice, I just now switched it out for the WWB flat point FMJ's, which it has shot reliably with in the past. My P3AT had problems with the AE FMJ, so I won't carry it. I have some Prvi Partisan FMJ but I haven't tested it yet. So, I'm now loading with the WWB. Hopefully it will get the job done, should I ever need it. It is a tertiary weapon, so the odds are against needing it, thankfully!
Oh, and to drift the thread a little, I also carry the 135 gr. Speer SB load in my 442-2. That's my secondary/weak side gun, with a Kel-Tec PF-9 loaded with 147 gr. standard pressure HST as my primary. Someday I hope to replace it with a Glock 26 or 27.
Keep up the good work!
