well, today i receive new recoil spring from HP. while changing the spring i notes my feed ramp look funny and i don't remember how is suppose to be. sorry for the poor picture. i use my cell phone camera. there is a semi-circle chunk missing on my feed ramp. it seems like the tip of my ammo sand off that chunk. if any one can be so kind check their c9 for me or even post their feed ramp on here, i'll be very grateful.
