No, sorry I didn't explain well. On the new style G the right side lever portion can be machined away. Approximately at the red line.

But the remaining small cylinder shaped part must stay since the spring is inside there. In this pic the spring at the lower left fits inside the lever at the left.

Here you can see new style on the left and old style on the right.

The old style right side lever could be removed by pushing out the two small pins. The gun functions just fine w/o the right side lever.
