Explain the "tuckable iwb" please...
@Sport45 - There's a reason many trainers are now considering firearms training more of a martial art. Most self defense shootings occur at contact range...cover usually isn't an option. Ideally you'll find cover, but most of the time that isn't the case. A fast draw can easily mean the difference between life and death.
Look up Hojutsu for more info on what I'm talking about.
Back on topic, Sundays are the only day I'll wear my IWB with my a shirt tucked in. That's at church. It's a compromise so I can still dress nice. I just have to blouse my shirt out a bit at he waistband, and by doing that, the gun is nearly invisible.
