I have to agree with Geojelly. Try a known good magazine and see if it helps cure the problem. also give the gun a good cleaning and look for any buildup of crud on the face of the bolt or barrel and clean and lube as you should. There is one other thing I would do as a matter of course and that is to replace the recoil spring asap. I can't tell you how many times simply replacing the recoil spring makes all sorts of problems disappear. Springs, especially recoil springs must be replaced on a regular basis regardless of rounds fired. Now if you shoot a lot they should be replaced sooner, but a recoil spring will loose power just sitting assembled in an unused handgun and is probably the most neglected part of many handguns. It may be OCD on my part, but I disassemble and remove the recoil springs on my semi-autos if I don't intend on using them for long periods of time. I'll bet it helps your situation if you install a new recoil spring.
