I recently picked up a Kimber Pro CDP and it's great. My plan is to use it year-round IWB. At one point, I thought of switching back and forth between the Kimber and one of my smaller pieces (Glock27, etc.) based on weather and clothing. It then occured to me that almost all my guns have a different manual of arms. Do I really want to have to remember which has the safety, which is DA, etc? Bottom line, I've decided to carry the Kimber year-round in a Milt Sparks VM2. I know lots of you guys do switch off. Am I being foolishly cautious? Is this making sense???
