I've had many ParO's over the years, never had a broblem with any of them, after a little break in period.
I have the GI Expert. I had several FTF's and FTE's in my first hundred rounds. This was only rectified by using mags other than the Para factory mags (kimber).
After that, the gun straightened out, and now feeds reliably (flawlessly for the last 200 rounds) with the factory mags that came with it and with the Kimber after market mags.
I wasn't thrilled at first. Now I am. It's a great, accurate 1911.
