OP- what do you intend on using the gun for? If hunting, I’d lean toward the 629. If range or non hunting I’d go for the 10mm. That is what I’d do if faced with your problem.

That said both can serve you well. Some will say the 10mm can do well for hunting, and it probably can, but think the 44 mag has more versatility for that discreet purpose. Some also may say the moonclips are frustrating to use. That has not been my experience, but understand how one can view it.

The 610 can also shoot 40 S&W while the 629 can also shoot 44 Spl.
