I've found this to be the case as well. Folks have attributed this to the tighter lockup of the shorter slide + dual recoil spring (difference now attenuated somewhat with the dual springs being standard in all Gen 4s)
And yeah, I say this in every G26 thread, but they're probably my sleeper favorite of the Glock lineup. Very shootable as noted by many here, and also highly versatile. Throw on a +2 baseplate and you suddenly have a bobtailed Glock 19.
These threads always remind me that I need to buy a backup to my 26. I'll poke around for good deals on gunbroker this summer.
