I use a Uncle Mike's finger grip sleeve on my JCP(40s&w) which is the large frame. Had it for years and has worked very well for me. Not tried a sleeve on the carbine models and the hand angle should be same if you do get a grip sleeve.
If one has sweaty hands or needs something to give more fullness to a grip, the sleeve is a good way to go.
