Got to say I like the feel of my gst 9 better than the p80 both are great but I think if your hands are med to smaller size the get fits better
Nice job!!
FWIW, I have large/xl hands (but not terribly meaty or fat), and I too, find the GST9’s grip much more ergonomic than the PF940C’s grip (we have both frames); albeit just a tad on the small side ( I’d prefer just a wee bit more girth)…installing the Hogue Handall Beavertail grip for Glock 19 really brought it where I like it. Amazingly so.
That same grip I’d originally installed on a P80 to mitigate the blocky nature of it, but removed it as it was a bit too much, in spite of making it it far more ergonomic than the oem bare P80 grip…but installing a talon grip decal on the P80 did make an improvement and I left it on. YMMV.
