shoots low

I currently own 2 Taurus Handguns. 1. Taurus 327 Federal Magnum Snub Nose Revolver. Same size as the 85 but it hold 6 round. 2. G2C which might be my biggest mistake ever. Really wanted to like this gun due to it's size & capacity, but the Damn thing Shoots 8 to 10 inches low @ 10 yard and there...
