So perhaps you can see your way towards going with a seven inch gun. Go for it and let us know how it works out for you. I have been looking at a six inch gun myself for a while. Have not been there yet.I have a couple 6" guns already. A 9mm and a 10mm.
My 6" 9mm is a Sig P210 - shown below, and my 10mm is a DW Bruin.
Taking out my Suppresed H&K Mark 23 usually gets some interesting looks. Just a bit less than eighteen inches overall.I'm still looking and trying to decide. I think maybe this year I've just got a few coins in my pocket rubbing together and I'm looking for something to do with them. There's nothing I need. Nothing in particular I even want. I had a wild idea that it would be fun to show up at a steel challenge match with a violin case and a giant off-the-wall 7" 1911 inside, but even then, it would only be a novelty. I can't think of any practical application for same - except for the 7" sight-picture.
