BevrFevr, When you do the mod you are still left with two safeties: 1. firing pin safety, which requires trigger to be pulled aft to remove firing pin block and 2. The slide mounted safety, which makes it impossible for the hammer to strike the firing pin. With the safety on you can drop the hammer with the trigger , but it won't fire. It is similar to the DAO setup, but includes single action cocked and locked as an option.
Another thing to try is using a 19lb hammer spring from a 1911 in the 92/Vertec. You will find the double and single action pull move to a very sweet range.
