factory mags are cheap, too. and everywhere.....
Exactomundo .... buy a couple and run them through and see if they give you different results. Since you're paying to have your gun gone over every year, seems like real cheap insurance to have some new mags.
If the new mags fix your problem, you can either clean the old ones and use them as spares OR sell them as here on the cheap letting the new owner they will need to be cleaned. Meesa thinks there'd be lotsa folks willing to send you some shekels!
