i used 1.5inch 23g guage for years. then i found 29gx1/2inch and havent looked back. only problem with these pins is volume. they are only 1ml
i might have to order some of these.You can get slin pin needles to put on a 3ml barrels, i draw with 23, swap to 29-30 when using slins.

i made a mistake last week and ordered 31g-1/2inch-.5ml for my greys. these things suck! the barrel is so thin you cant backload cause it backs up and the pin gets super dull going through the rubber stopper in the vial. ill be tossing these!
