Bigger slin pins?

[outlawtas]

Do slin pins only come in one size? The reason I ask is because I just got my MTII from Ology, and the instructions say to do "deep intramuscular injections with a slin pin". I thought they were generally only 1 size, and if not, do you think standard (I believe 1/2''?) is deep enough?

thanks.
