4 different types of ammo. Magazines and gun disassembled and cleaned multiple times. I have not done any DIY "gunsmithing" on it and don't feel I should have to, since I'm not a gunsmith.
I own nearly a dozen other (non-KelTec) guns and excluding one (an EAA Windicator), they all function reliably and are 100% dependable. I even own two other KelTec's and have no trouble with either of them (KSG & Sub2000 V2 9mm).
KelTec got back to me this morning and asked me to send the PMR-30 in, and that I should expect it to be in their hand for 5 to 8 weeks. Looks like shipping is on my dime.
