Okay, thanks. I think your loads are probably fine. They're within Lyman's data, though at the max pressure of 32,500 CUP (SAAMI max CUP is 33,000 for 9mm).
The Zero RN JHP measures 0.525" long, and the data was for a Hornady bullet that measures 0.545" long (my samples), and you're loading them a little longer than the Lyman's load at 1.090", which should help to reduce pressure, all else being equal. As long as they fit okay in your Glock barrels, you should be fine.
But here's what I'd do. Load about 10 rounds with 6.0 grains of True Blue, and about 10 rounds with 6.4 grains.
Try those and watch for pressure signs. In this case, what you're most interested in is excessive bulge in the unsupported region of the chamber. Are you familiar with this? If there is no excess bulging with those loads, try your 6.7 grain loads, watching for the same thing. If they look okay, you're good to go. The bulge is usually an issue with the gun, and not the ammo, when working within the normal pressure range. If you get excess bulging, they are too hot for your gun. They might be fine for the 17, but not the 19, for example, or vice versa.
But, next time work your loads up with a few samples, and check for pressure signs, before loading a bunch of them.
