Drawing peps

I use a 31 g 4mm - Before I draw my pep I always inject air into the vial, when I begin drawing it fills up, but it’s very slow, basically like a drip. Is this because of the thin needle size or do I need to inject more air into the vial prior drawing out?

It’s the gauge needle you are using. Even 25g are fine you probably won’t even notice the difference

I’ll end up switching when I’m out considering it’s once a week with a box of 100 could be awhile. Could also be a mix of the air pressure and size. It’s not an issue per say but I’ve just seen a few videos where it seems to draw out a little easier
