Just as an FYI & I was checking into "wimpy" 9mm bullets by Remington/GS ...
Talked to the chief LEO sales guy at Rem (mumble = his name) for about an hour an a half quite a while back.
GS appear, by all the imperical data (penetration tests, etc. which, at the time, were not published by any other bullet mfgr), to be as good or better, than any other bullet out there.
The rep did say that LEO reps had a real problem with jacket separation - even tho' the lead core still penetrated to the 14"+, etc. (as an aside, I couldn't care if the jacket blows off to create a secondary wound channel & actually, it sounds like a good idea, IMNSHO).
Anyway, Rem does a LEO-only bonded core to jacket that us mere mortals can't get (through normal channels anyway). The LEO only bonded jacket doesn't penetrate any better than "ours," the jacket just doesn't separate. Whoop.
Like I said, just an FYI re what I got outa the Rem rep ....
I carry 124 +p in my BHP/9 & most certainly stake my life on 'em. If I had GDs, I would feel just as secure. Mind-set to not become a victim & bullet placement if you do are probably THE most important aspects.
Kinda wish Barnes would do a low-drag sabot 9mm round ... say a 95gr HPBT at about 1800 with 25" pentration at 100yds.
