need some advice building open glock for young girl. looking to have as little felt recoil as possible so the shooting is enjoyable. so i have a glock 17 with fastfire mounted with dovetail mount. looking to putting carver 2 port comp on it or possibly putting a ported barrel on it. please offer all advice except switching away from the glock. been practicing with 2.6 gr of titegroup with 148 xtreme bullet i know it does not make minor power factor but just getting her used to shooting. our normal load is 3.2gr. look forward to comments.
