I have on one of my P-32's It works fine IWB for me. Not fastest draw in world but better than empty hand .
I always carry my pistols ready to fire . The long trigger on the LCP or KelTec is safe. If pistol is IWB or pocket It going to be darn hard for something to pull that trigger and you not know it.
Don't you think in to days sue happy world If this wasn't safe Someone would have had a discharge and sued by now. This type carry been around a long time in different ways. It's not just on a Ruger or KelTec.
