Reverse Engineering

They've been around for a while, but today Caleb mentioned a metal frame for your Glock.  Glock is probably the most responsible for bringing plastics into the serious handgun game, freaking out the libbies all the way (ZOMG IT GOES THROUGH METAL DETECTORS!!!11)

I was going to say the only thing that they need is a steel frame for your Glock that mimics the 1911 grip angle, but then I noticed-

One of these backstraps duplicates the factory Glock grip angle. The other is flatter, resulting in the pistol pointing more naturally for the vast majority of users and mimicking the grip angle and feel of a 1911.

I have to agree with one of Caleb's points though, if you must have a metal framed pistol, just stick with a Sig or something.
