Matt did his homework while designing the Cheely E-2 metal grip. The beavertail is fixed (not a safety) and cut deeper in, the texture is much more aggressive, and it seems that the backstrap is slightly more vertical than the Legacy (original Cheely grip). It can be had in either stainless or aluminum and comes with a choice of 3 different magwells, mainspring housing, mag release, and beavertail.
