So I'm looking to upgrade the stock sights on my G20 and would like some input as to which route to go. It is mainly carried as a woods gun/hunting backup, but also home defense with a Lone Wolf .40 S&W conversion barrel. I've narrowed down my choices to either the Truglo TG131G2 or the TG131GT2 and need help deciding which one to go with. On one hand, I like the contrasting colors of the G2's (front is orange and rears are green) and they are about $22 cheaper... But on the other hand, I like the idea of having their TFO (tritium fiber optic) technology on the GT2's for home defense purposes. Any input or feedback would be greatly appreciated. Thanks.
