Yeah, true enough; different ergonomics on different handguns can affect your shooting.
Had a SA XD-9 that I was ALL over the map with. Traded it for a Glock 17, and that’s a tack driver, like my G19. Sat in my hand weird, and just never felt “right”.
Had a Beretta C92 for a while, but it never fit my hand too well, so I got rid of it.
Also shoot the G21 and M1911A1 pretty well too. Both strong and weak hand.
It’s all good stuff, though... depends on what “fits” you.

And especially “weight” for me. Too heavy or light? I ain’t no good no way, nohow : )
