no. this will open you up for abscesses.
use 1 inch minimum. if you do glute shots and you are a big boy i would even suggest 1 1/2.... for prop use atleast 25G, 23G is much easier though. you will notice its hard to draw using a 27G, just imagine injecting into a muscle... injections should be smooth and easy, thats why i always use a 23G.
