Just do the G conversion. Its easy. While your at it install a Langdon Tactical trigger job in a bag. Makes a world of difference in the DA pull. Mine is about 6.5 lbs and super smooth.
Totally agree with the other recommendations for Silva. Have one for the last 40 years and managed to never break it all through Scouts and the Army. Got the job done for me all over the world.
