its a start. Hard to coment at a stage like this. One thing I did notice though is you have no edges going to what I belive is the thumb hole there. This could make it nearly inposible to work with there, make changes etc. As the hole is lost in the one big face that acualay serounds it. On your triger hole you have a edge going to it.. If you redo that spot I would sugest befor makeing the hole to have a edge going acrost there to split the face up in to 2 to give that hole something to bit in to sorta speek.
