I just ordered it, but i like to have it ready when i pick it up from the gunsmith. I will have the thin grips installed, the version i bought is with fixed sights. That was the only one left, so i have to have adjustable sights installed. I like à small front sight. Do you know à .90 front is production legal? And i'm free to pick any adjustable rearsight i want? I tought it is à production rule that you have the sights that the productionline of the factory makes.
