Hay myronman3: Ya know, if you get yourself a 10mm, you can get a barrel for the 9x25mm round, which is a 10mm necked down to 9mm in the same fashion as the 357 sig - I forget who designed that caliber but it's the fellow (Mike somebody) who sells all the blue stuff and makes the progressive reloaders and has the pretty girls, who are properly dressed, on his half sized magazine covers. Dang, this CRS drives me nutz! Anyhow, there's a pair for ya, the 10mm and it's skinny brother - I'll bet that 9mm moves out close to 1600'/sec or so - nice flat shootin' vermit load.
Dillon, is the name, and I think he designed the 9x25mm.. Whew, it finally came to me.
Now, someone is going to have to clarify this for me but I wonder if the case head on a 38 spl is about the same as the case head on a 10mm and if it is, then you can get yourself a 38 spl bbl for that 10 and shoot target, too (if ya wants to). Or, if you want light loads, you can always load the 10mm down to 40 S&W velocites or get yourself a 357 sig bbl or just about anything you want to do. I love the 10s, I think they are great.
Now, as for the revolver business - the Model 19 in 357 is designed to take higher pressures than the 10mm, I believe (I think the 10 operates at lower pressures). If I had the $ and the time to toy with it I would have a Model 19 reworked to handle the 10mm - that would make a heck of a nice field piece. If that worked I would love to try the same with a Model 27/28 in a 4" or shorter bbl. The 10mm does not match up to the 41 magnum but it would give you a healthy round to have with you in the field. I know that a 170, 180 -200 gn 10mm will T&T a whitetail at 50 yds and might just be the ticket in medium to large frame S&Ws without all the fan fare of their trying to make up a revolver to compete with their 41 Magnums.
However, since this is only my 2 cents worth I am open to suggestions, criticism, nit-pickin' and a couple of burgers since it's getting close to lunch time. Mikey. :-D
