My Colt Lightweight Government 45 was a snowflake gun if that's what we're calling carry guns that actually get shot regularly. But I recently bought a steel-framed Colt XSE in the same configuration to serve as its training counterpart so I guess the Lwt Gvt has lost its snowflake status.
I have to confess I'm still a little fuzzy on the definition. To me, having a carry gun that gets shot a lot is just an indication of lack of a training analog.
