Euclidian, I sold my 629-4 almost the same gun but it did have the new style extractor and crimson trace grips on it for $700 in about 10 minutes at our gun show here in AZ this weekend. I can't shoot it anymore my bones won't take the recoil , but I it was the best wheel gun I've ever owned and I loved it's accuracy. For such a beast in magmuns it was dead on accuracte. My smith said the most important for this model is that the lockup be tight I put about 2000 magmuns through mine with zero problems. The 4 seems to command a premium here. Hope this helps.
