Couple suggestions. If you flip your sight and BUPS. When using your BUPS you will have greater accuracy from a longer sight radius. By putting the sight on a riser, you will have better cheek weld and will be able to have a co-witness (with absolute or 1/3) with your fight sight, instead of the dot being blocked by the FSP. Remove the mag holder thingy. If you want a spare mag, put one on your belt or get a Readi-mag.
