I am interested in getting a S&W Model 25. I have wanted one for years and I am very close to acting on my desire.

My question is whether there is any one official resource, from Smith and Wesson, that lists all of the Smith and Wesson handgun models and the corresponding ammunition that a particular model can handle? From what I have been able to determine, the Model 25 has been released in at least 15 sub models, each with different specifications of ammunition, and barrel lengths.

Specifically, I would like to know whether a Model 25-15 can safely handle .45 Colt +P. But I thought a single Smith and Wesson resource would be a handy reference for all of their handguns. No offense to those very knowledgeable hand gunners, but in this case, I am not interested in opinions, only fact. I may come across other model 25s and would like to know about them.

I realize that +P ammunition is not recommended for use on a regular basis in most guns.
