I would go with a Semi, I'm a big fan of the Ruger SR9c. Great trigger, good sights, 10-1 rounds double of 5 shot revolvers. Plus you can carry a 17 round back-up. You already have a semi so carring one is no big deal. Pick it up point & shoot, or pick it up swipe off the safety and shoot. Why limit yourself to only 5 rounds.
