Internal parts for Springfield EMP 4?

Competitor who is sensitive to pistol weight is thinking of Springfield's 9mm EMP 4" (Lightweight Champion - PI9211L).  AR of June 2016 - I think - has article about the down-size 1911.  Not clear which internal parts are smaller than standard.  My advice is to try to discover if parts are available.  Likely that would need to replace trigger and/or grips to deal with short fingers.  Probably not going to be used outdoors. 

Ideas?    Thanks.     Mac

The contour model looks like it might fit a small hand better.

A fellow competitor brought a Contour model to be tried.  The "bite" out of the grip was below hand and the appearance was too modern.  [Everybody has their likes and dislikes.  I only see sights when using pistol.]  The earlier Champion is a little less expensive, and more conventional (so it looks more like a 1911).  

Have learned that many choices for grips exist - have to specify.  Do not yet know about inside parts.  Thanks.

If I had small hands and weight was a factor I would probably go for the Browning 1911-380. Looks like a 1911 just smaller. Only weighs 17.5 oz. You have probably already looked at one of these but maybe not? I know they make a lot of grips for them.
