Loading and firing is pretty simple. The safety is actually a transfer block with the safety located on the right side in easy reach of the thumb.
To load you have the safety on, cock the hammer, open the lever and drop your round in.
After loading with the safety still on you can lower the hammer and if it were to slip the MOA would not fire.
In this picture you can see the back of the fireing pin with the trandferr bar in the safe position.
To fire a round you cock the hammer and move the selector to fire position. The transfer bar will move up over the fireing pin. At this point the gun is hot.
In this picture you can see the transfer bar down. In this position you can unload the gun or lower the hammer safely over a live round.
And talk about a trigger, these things are sweet.
