Just wanted to share this info. Hopefully its helpful to others.
My wife was having some bruising form using 1cc 29G x1/2" when shooting Glow and Reta. So i switched over 1cc 30G x 5/16".
The new 1cc 30G x 5/16" seem to be causing less bruising on my wife's belly. Also the 1cc 30G x 5/16" seem to be cheaper. I was able to purchase the new syringes for about $11 for a pack of 100.
Photos comparing the two syringes below:
