JLaw,
http://www.smartcarry.com has pictures. It's a cloth holster that rides right behind your 'fly'. As long as you keep your finger off the trigger when you draw there won't be any problems.
Heck, I like mine. It works fine for the times that waistband carry is not an option. I wear dress slacks that are pleated in the front and it is very comfortable. For me it works with 'relaxed fit' jeans also, but they need to be on the big side, but you would need that for IWB anyway.
I have a Hoffner Hybrid, which is a kydex tuckable IWB. I have tried tucking in my shirt to cover the gun. It is probably just me but I can't get my shirt untucked and get at the gun in a reasonable amount of time with out looking like Houdini trying to get out of a straightjacket.
On the other hand the draw from a SmartCarry is reasonably quick and smooth.
Butt pack is an option too, sometimes, but not for a family portrait!!
Iknow, Iknow, butt pack "screams gun" and it's not manly etc. I saw a Scottsman on TV the other day in a kilt and they wear something around the waist to take the place of pockets. I thought, hey a kilt........., never mind!
Regards, OE
