I'm starting to learn more & more about S&W revolvers. So far I've learned that the model 19 (a .357 mag) would rather eat 38 specials but will do the mags once in a while. For some reason I shoot the model 10 the best out of any handgun ever. I want to get in to a magnum that will get shot a lot. The model 13 looks to be built on the same frame as the model 10. Will the 13 fall apart after a steady magnum diet too? Or should I be looking at the 27 & 28's?
