I honestly don't see what you need to do. A 7 3/4 lb DA pull is from 2/3 to 1/2 the weight of a DA revolver pull. Other than maybe a little polishing to smooth it out I personally would consider it good and just start practicing with it as is. Lighten it too much and you may start having failures to fire. Personally I would just work on the transition from DA to SA from low ready. My range doesn't allow work from the holster. Decock and fire 2 or 3 shots and repeat until you've got it down. It looked sweet to me as is. But hey it's your weapon, more power to you.
Never argue with an idiot for he will drag you down to his level and beat you with experience!!!
