Looking at the original trigger bar, it appears to be minutely chipped, just enough to slip off the hammer. The new bar worked perfectly and the gunsmith ran 5 rounds through it. So I took it and a box of Magtech 71 gr. and set up a B27s target at 7 yards. I ran 32 rounds through the gun using both its original magazine and the one from Legacy that donp326 posted. I started each mag double action.
Results? The gun ran all 32 rounds without a bobble and kept all shots in the 9 ring. DA to SA transition was hardly noticeable, but thumbing the safety to fire was. Mag changes were easy. All in all
a great time, as good as getting a new gun, maybe.
I should mention the grips as my originals are too fragile to use. At first I tried I tried some from Triple
K: don't waste your time. They came warped(along with instructions on what to do if they came warped) . So, I got some from N.C. Ordnance which worked fine for shooting although they are slightly oversize.
Thanks to Warbird and donp326 for the tips and all who responded.
