Witaj na Forum! Model 629s, especially early "no dash" models, are very popular here on the Forum. The Model 629 (6" barrel) was first introduced by S&W in 1979, and the 4" and 8-3/8" barrels were released in 1981. Your two nice 4" revolvers were manufactured in late 1982 or early 1983 and overlap the release of the Model 629-1 (eliminated P&R) in 1982. Front sights should be red ramp, so the black front sight insert on one of your revolvers was changed out at some point by a previous owner. Also notice that the Goncalo Alves checked target stocks are different...one has the extractor relief "football cut" on the left stock, and the other has the later "speed loader cut". They may both be original sets of stocks since speed loader cuts were introduced in the early 80s, and football cut stocks were probably still being used. You have a couple of very nice revolvers, and I hope that you intend to shoot them. The rest of your collection is very nice, as well. Cieszyc sie!
