1200 made in blue and 1800 made in SS.
They were the first run of full lug barrel 29's and 629's to kick off the introduction of the "Classic" models so they were made before the "Classic DX" models were introduced. They were held to an accuracy standard and shipped with 8 front sight inserts and test target. The 7.5" barrel was/is unique.

The Magna Classic and early Classic DX revolvers were tested at 50 yards to stay under 2". The later Classic DX revolvers were tested at 25 yards and held to 1.5" so it is safe to say that the Magna and earlier DX revolvers (629-3 and 29-5) were held to a higher standard of accuracy then the later DX revolvers (629-4 and 629-5,29-6).

So to answer your question they were just as accurate as a DX, yes.

Nice revolver you have. I still need one in my collection.
