With the changing of the weather, so changes how most people dress. Colder weather mean big heavy coats, gloves, and other things that could change what and how you carry, and/or how you might access your gun.
Do you practice with these changes? Can your finger enter the trigger guard with those thick gloves on? Can you get all that coat and clothing out of the way and perform a clean and fast draw? If you’re using a different gun, are you familiar and proficient with it? If you don’t know you should find out. Fifteen minutes of dry fire in your garb will tell you much.
My coat has a Makarov pocket, so I’m not too worried. 😉
