What you are describing is a Colt style ambidextrous safety. The left and right thumb levers each have half the pin that holds the grip safety and fit together with a tongue in grove. The right side lever generally has a milled edge at the front that fits into a slot cut into an extended sear pin. This holds the right lever in place without requiring modification of the grip panels.

The safety system can be replaced with a standard GI type 1911 safety and sear pin. However, the sear block on the safety has to be fitted to the individual gun for 100% safe operation. This is not a drop in job.

If you want to try it yourself, there are videos on YouTube demonstrating the process, but it isn't always as easy as it looks. If in doubt, have it done by a qualified smith or armorer.
