Several ex-military with ccw licenses who are members of my church have been requested by church officials to consider quietly start carrying concealed during Sunday services. If I wore a jacket I would carry belt or paddle and my SIG P220ST. However, I wear long sleeve dress shirt and dress slacks so am thinking ankle holster and my Glock G30SF. My first question is if the G30SF is too large/heavy for a good quality ankle holster. If the answer is it is not too large, then my second question becomes what manufacturer/model holster do you experienced guys recommend. If the G30SF is too large/heavy, what is a more reasonable choice. Thanks.
