my first quad shot, i made the mistake of moving my leg while the pin was in...fuck that hurt, and thanl god i did not snap the pin, also, when you shoot bro, dont push the pin in all the way..if there is a break at the pin/syringe, at least you can attempt to get the pin out...and also, if anything else happens, dont freak out until you get the opin out...dont swab the pin with alcohol before you put it in, and always aspirate....
On that note, not a problem, and painless..but, if you shoot zambons (winny), they will sting....
