Some weapons have a steeper learning curve than others. All else being equal, a weapon which fits one's hands will have a gentler learning curve. For most people, this is means something like a K-frame revolver. Unless a person has tiny hands, a J-frame is not going to be a best fit. That being said, a beginner can learn to use a J-frame, such as the Model 36.
All else being equal, a longer sight radius is easier for learning marksmanship principles. While barrel length is independent of frame size, of course, few 4" to 6" barrels are to be found on a Model 36.
All else being equal, prominent sights are better for learning marksmanship. Except for rare exceptions, Model 36 means very small sights.
I start new shooters with my K-frame S&W Model 17, which shoots .22LR ammo. Fast learners will progress to a medium-frame with .38 ammo, and be shooting a .45 auto within the same range session. Something small, such as a J-frame, is rarely fun enough to find much favor, until the shooter desires
something seriously concealable, or wants a bit of a challenge. The rare exception Is the beginner who has small hands, well-suited to a small grip, plus a bit of hand strength.
