That site has a short article about using a product called "Clipdraw" as a point shooting aid. I ordered one for my model 1911 & it arrived in just 2 days. It's designed so that you can carry a handgun (which you should only do lawfully, of course) inside your waistband without a holster. The clip slides under or over your belt to hold the weapon in place.
It does away with the need for a holster, and my .45 clings to my side with no telltale imprint. The big bonus, though, is that it provides a rest which keeps the index finger away from the slide (or force cone gap) when you're point shooting. I've not tried it with live fire, but as I've experimented dry firing at various ranges, it appears -- to me, at least -- to be hard not to line up dead-on with this item.
I'm not a big fan of shooting gadgets, but the clipdraw is simple, it's low tech, it required no modification to my weapon, and it was a snap to install. It might even motivate me to work on improving my draw (especially after my last post).
If you're interested to check it out for yourself, here's the link:
