Re: the FTF issue, that is a common problem. There are many excellent suggestions in the thread. But, if those ideas don't improve performance, I would suggest a tape test (do a search of this forum and the other forum as to how) to see if the toggle is coming all the way back on recoil. If it isn't, the mainspring can be removed, a fraction of a coil (say 1/2 coil) cut off, and the pistol test fired. The process is repeated until the toggle achieves full travel. I have fixed a couple FTF issues with this procedure.
