Pinning in the pec?

[noclue]

if you are worried, you can always cut the needle cap cover off about 3/4 of the way down and recap it , that way the pin will stop short of one inch

just make sure you hit the meaty part of your pec. I believe the diagram shows like one inch above the nipple and a little in toward center

Yeah, got the spot from s p o t i n j e c ... but I'm not sure what you mean by "cut the needle cap"?
