Oh...I dunno...I've toted both and the Jaybird with it's rounder curves seems to tote a little easier in the pants pocket than the G27 does.
Now if we were talkin' about "shoot me first" vest pockets or even pants cargo pockets, then yeah, I would give the G27 the nod.
But it's just too damned square and bulky for front pocket, pants carry.
I always giggle when I hear 'em called that.
