Many years ago I used to get allergy shots. There was a nurse who would put the needle in almost like you would throw a dart, and then shift grip to use the plunger. It was strange and alarming when I first saw it but I had to admit it was the most painless shot at‘d had in a long time. That’s completely different than trying to hit a vessel to draw blood, though.
IM and Sub Q injection are very different than a blood draw. You don't need suction for an injection, and apart from needing to be in a vein, the suction is one of the bigger issues here. Too much suction and you collapse the vein and end up (likely) having a hemolyzed sample-at worst you don't get any/enough blood and have to start over.
