The 940 Centennials are a great little revolver, but hard-to-find. Back in the mid-80's; I purchased a Ruger SP-101, when I came across it, in a local gunshop. A solid, performer that does night-stand duty now.
I recommend the S&W 610 revolvers. The 3 7/8" version is the perfect-length for a field revolver. Excellent companion piece to 10mm 1911 autos, like the Dan Wesson Razorback; or any .40 S&W pistol.
My 625 has always been a favorite, and the perfect augment to my Kimber Gold Match. I'm a big-fan of all revolvers chambered in autopistol calibers.
The 610's, also rock!
To answer your original-question; the 610's are burly field-revolvers.
They give you the option/alternative to shoot both 10mm, and .40 S&W.
Most folks who own 610's are usually 10mm mavens; who collect handguns chambered for this round. Typically, they own/acquire S&W's 10xx-series of...
The 9mm NATO is quite manageable in a 'snubbie' revolver as others have mentioned. Also, moon-clips are the way to go. I've had mine [Ruger SP-101], since the late-80's.
I've always been a fan of revolvers. But the popularity of 'wheelies' is cyclical, and they seem to come in and out of vogue. Their biggest plus is their reliability, simplicity, and versatility.
