I bought the Rossi 22 mag over a month ago and used it one say where the charging handle was missing after firing a few rounds. I could not find the charging handle and took it back to the gun shop. They sent it back to Taurus which took about 4 weeks. After getting the rifle back i used it today and the charging handle came off multiple times. I hesitate sending the rifle back after different reviews that I read. Does anyone know what the issue is and how to fix?
