Most often it's a Kahr cw9 in a Gould & goodwich iwb holster at 4:30. If I feel like it I'll wear a glock 19 in a bianchi allusion iwb holster also at 4:30. When I need more concealment or just to save time I'll use a s&w 442 in a bulldog pocket holster in my front pocket or in my jacket pocket.
Glock 27 Gen4 in a Little Foxx IWB holster at 4 o'clock position, always with a round chambered. Mostly use the 10-round mag but will go to the 9-round mag if it needs to be completely concealed in warm weather.
