I just wanted to be a smartass.Gee thanks, I wouldn't have known that fact.
I was replying to @bcannon about the ergo's between the two pistols.
The p10 has more of a palm swell to it, compared to the p09 which as you know is pretty slim, both have back strap systems which is nice. The p10 has (in my opinion) better grip texturing too.
That’s about all that I’m aware of, I’ll leave the floor open to others with more experience than me.
