While I won't say that what you've got is a bad loading, I too would be hesitant to trust my life to something that so little is known about.
sub-100gr 9mm loadings don't have the best track record in the world as, with JHP's, they usually expand violently and/or fragment at the expense of adequate penetration. Conversely, JSP's don't have a particularly good reputation against people as they typically expand little, if at all, in upright bipeds.
It is possible, I suppose, that perhaps the combination of a 90gr 9mm with a JSP bullet might work OK as the increased velocity possible with such a light bullet might facilitate rapid expansion while the less-aggressive bullet expansion might alleviate the typical retardation in penetration. I would not, however, count on this hypothesis as JSP's at similar higher velocity than that you cite (1350 really isn't all that fast for a 90gr 9mm) still have reputations for lackluster penetration. Such loadings include the 125gr .357 Magnum and 180gr .44 Magnum JSP loadings from most major U.S. ammo makers as well as the 100gr 9mm +P+ JSP loading from Hirtenberger.
The Hirtenberger loading in particular is quite interesting because, as I understand it, the point of the JSP bullet was not expansion in soft tissue but the prevention of ricochet when striking hard targets like car bodies and pavement. As a side note, I've shot that particular Hirtenberger loading in both a Sig Pro 2009 and CZ-75B and it was among the most accurate 9mm ammo I've ever fired.
Basically, I agree with others that you'd be better off to simply load your gun with a proven 115-147gr JHP like Winchester Ranger, Winchester PDX1, Remington Golden Saber, Federal Hyrda-Shok, Federal HST, or Speer Gold Dot. Use the 90gr JSP's for the range.
