Query: sorry i bought it

the gun is heavy / big / huge diaphram head / and has ricocheted 8 nails so far, 3 of which has hit employees. we have shot about 350 nails with this gun and it is very finicky. it has a guide that is supposed to "move" and allow the nail to enter the hole but sometimes it just shoots the nail back at your face at a high rate of speed. It is dangerous and I am going to try to return it because it is dangerous.
