a buddy of mine did what was mentioned above. go to a Feed Store, and ask for a puppy vacciantion shot. it will be like $7.00. it will come with a sterile pin, and two bottles of vaccines -one powder, one liquid., just toss those ( unless you need a parvo shot). the needle is perfect for GEAR. shoot your quad, i think they are only 1-1.25 long. you'd be paying $7.00 for one pin, butr you wouldnt mess up your schedule.
