9mm familiarity
I got my first gun in the late 90’s. Then, as now, Glocks were big. .40 was too, unlike now.
I shot friends’ Glocks, but recall not being impressed. Don’t remember the exact reason.
Recently picked up a G22, a .40 caliber service sized. My first Glock. Have taken it to the range twice now. Both times I carried my 940. This second time, it occurred to me that shooting a 9mm stainless steel J Frame revolver is a similar experience to shooting a polymer framed service sized .40. Similar recoil and time to reacquire the target.
.40 is the sweet spot for me. I suppose that 30 years does that to a person. But it might help explain my affinity for the 9mm revolver.
