Any ideas on where I can get some grips that are smaller than what come with a Model-41 and will fit the Model-41?

Check out the Herrett Grips T41 they might be what you are looking for.
Herrett have a web site and pictures are shown on it.
Cheers.

Thank you for the information! It is much appreciated.

Yes, do check out the Herrett "Trainers". I own them and like them. I guess the idea was to give the same grip-feel as a 1911. While that might be fine for a rank beginner, I doubt most of us will benefit that much. But, I do like the quality of the grips and the way they look when mounted. They make the 41 remind me of a stripped Harley, which is cool.

I'd rather ding my Herretts than my original stocks--the ones I sometimes call "skirts" or "dresses".

I will give the opinion here that the stock 41 grips are that way for a reason. No way do the Herretts make me a better shooter that the stock grips.

The Herret H-41 grips are another option although probably not as thin as the Trainers.
