I am torn between the gen 4 and gen 3. I have read a lot of both positive and negative. As a first time gun buyer its hard for me to make this decision on my own. Any of you have an input? is the RSA and back straps worth the extra money? I am forced to buy because I am getting a job as a correctional deputy and need a duty weapon. Any input would be helpful thanks!! Wanna kill these ads? We can help!
