Great find Hoot. I was shooting some IDPA matches 8-9 years back, one of the fellows used a 610. He loaded .40 S&W rounds on the low end of the power range, recoil seemed almost non-existent.
As for clips.
You will surely want these, I have them for my .45ACP and they're great.

This is also a great tool to assist in loading and unloading the clips, be sure to check out the Youtube video link the site provides.

Hope these are of some help & see you soon.
