I use all standard 44 magnum loads from all the regular ammo manufacturers. I don't really want to comment on an open forum for reloads as Taurus will negate the warranty if they can link you to reloads.
There is a guy on ebay who makes wood grips for the M44. I am sure someone will be along with a link for you. I think Altamont (spelling?) makes them too.
