I got a Little Bear tuckable that works great. Others out there too I suppose but Dave calls and discusses your height weight body type and customizes your rig.
With the size of the LCP and a tuckable, I can wear dress pants that are sized normally and tuck in my shirt. I read where some carry a mag holder made from a small camera or phone case, or just in there weak hand pocket.
No prob sitting down or driving and the pistol is usually muzzle toward the earth if that is a consideration.
You can't go wrong with IWB LCP carry.
