Off the top of my head I believe that the 9mm JHP bullet in the 124-135grn range DID NOT expand fully when fired from a sub-compact (XD-GLOCK-TARUS)semi-auto frame into gellaton at 8yrds resulting in less than stellar performance by manufacturer's claims.
Muzzel velocity was greatly reduced to the 700-900FPS range being fired from a 3" barrel instead of the normal 1000+FPS (longer barrel) to achieve max. spread for max. damage/penetration.....
I'll get the aritcle and try to post it, cause I'm sure my facts are a bit "fuzzy". But I DO remember them questioning if buying "defensive ammo" was worth the cost.....or stick with FMJ target ammo to get better results.
I'll post it ASAP.
