I've seen it bandied about and I think there is an intuitive sense of what is and is not a "snowflake" gun. But I want an answer for those that use the term -
What constitutes a "snowflake" gun?
How much or how little support does a firearm "platform" need to be considered for snowflake/non-snowflake status?
If you're not a snowflake are you a raindrop?
Does caliber matter? I.e., a Glock 19 is a raindrop, but is the Glock 32 a snowflake?
