Winter requires that we adapt our clothing to the conditions. When we are required to wear more layers of clothing and gloves, we find ourselves at a distinct disadvantage.
Wearing a heavy cover garment can be a wonderful advantage to concealment, however it can also hinder a rapid draw. Some things to consider are length of the coat if you zip it up, as well as how tight the coat fits. If your coat is too long and it is zipped, accessing a belt holster can be very problematic. If the coat is too tight, it may bind during the draw. Drawstrings are also a risk. The drawstrings at the bottom of your coat can offer another snag point on the draw. I recommend that you cut these strings off or, at a minimum, tuck the excess.
Have you practiced in your gloves? Will your glove fit inside the trigger guard? Finding out now if your clothing is compatible with your carry gear is an important step. A thin set of gloves, while not quite as warm, can make the difference in being able to use your firearm.
Always be safe and remember the 4 gun safety rules!
