Why arn't there S&W model 15 revolvers on the firing line

Isn't the M 15 Combat Masterpiece, the same as the M 14 except for a shorter barrel ?

basically, yes. and, for some strange reason, it's now allowed in the revolver distinguished matches.
shorter sight radius is not always a good thing.

"now allowed" or "not allowed"

OK, it's allowed in the NRA Distinguished Revolver matches (with no modifications and meeting trigger, etc.) and of course for Centerfire pistol matches (again meeting the rules for trigger weight, etc.).  

It is on the list for CMP Distinguished Pistol (Service Pistol), and meets the requirements (if the trigger weight is correct) for Match Pistol (basically  NRA Centerfire again) and Service Revolver matches.  (It was an "issued" pistol at one time).  
 
Pick your competition and peruse the relevant rule books, although the CMP continues to get more complicated as we go along since they cover so many different matches.

I have a K38 Heavyweight Masterpiece from circa 1950 and a Combat Masterpiece circa 1955.  The Combat Masterpiece barrel is shorter and has a different contour.  The weight of the K38 Heavyweight Masterpiece is 1041 Grams,  958 grams for the Combat Masterpiece.

Thanks for the replies...Jim

The option of having one gun for both Distinguished Revolver and Service Pistol is interesting.  Particularly since I have neither a DR-legal pistol nor a Suitable (anyone try a FN FNX45 with combat sights at 50 yards ) SP pistol that still meets trigger weight.

CMP doesnt list the M14 for SP, just the Model 10 and 15. 10 looks like a no-go on sights. It appears that the M15 in some special cases was produced with a 6" or 8 3/4" (or 2") instead of the standard 4" barrel. I'm guessing the 8+" would exceed sight length restrictions. If I ever found a 6" that was produced as a 6", this would be considered approved/legal? Such as:

Again, check the rules:

CMP:

4.1.4 Other Approved Service Pistols
Other Service Pistols listed in Table 3 below may be used in CMP Sanctioned Service Pistol Matches, provided they comply with Rules 4.1.1 and 4.1.2 and have barrels no longer than 5.4 inches.

Lol!
Interesting question!
A true Unicorn, that one!

I earned some of my DR points with a Model 15. It is just as accurate as my K38, but the shorter sight radius makes it easier to pull the trigger when my hold is wobbling around. It's a little better balanced for me also.
