Hey guys and gals. I picked up a very clean but used 22/45 Mark III the other day that I discovered has a slight problem. Sometimes the bolt wont close all the way,or strip off the first round on a reload or on a fresh magazine loading. It happens with both the bolt release lever and during "slingshoting" the bolt. It came with 5 magazines and it will do it with all 5. It doesn't do it all the time, but it will do it about 60% of the time. Took the gun apart and cleaned and lubed it, also took all the mags apart and cleaned them as well but the problem still exists. Any tips for a first time 22/45 owner. Thanks. P.S--- I did notice when this happens during a reload, if I take out the magazine, close the bolt and then re insert the mag and slingshot it, it will chamber that first round. After the first round is chambered it runs flawlessly.
