It really isn't new. Smith & Wesson produced 5,000 Model 610 10mm Magnum N frame revolvers in 1990-1991. However, they have noe resumed production and the 610 is listed in their current catalog. I saw one the new ones at the range on Sunday and fired 12 sots at 50 yards. It was very accurate and an impressive piece. It seems quite similar to a .41 Magnum in power and recoil. It loads with halfmoon clips like a .45ACP Model 625. It would be a nice gun for anyone who has a 10mm Magnum automatic and wants a revolver using the same cartridge.
