A few years ago, I shot both a [9mm] Glock 17 & a [.45cal] Glock 21 at a local shooting range.
FWIW, I was able to get a tighter cluster with the more massive .45. The 9 simply felt too light to me. :dunno: I understand now why many referred to the 9mm Glock as "Combat Tupperware" upon its release.
Just thought I'd share my limited experience.
