The snub’s advantages are subjective and so too are its disadvantages. Whether one element of the snub’s design is an advantage or a disadvantage depends upon several factors including the shooters skill level, his familiarization with the weapon and the weapon’s expected role to name just three.  Consider the example of the heavy trigger-pull. To one shooter a heavy trigger is a detriment to optimum shooting. To another shooter that same heavy trigger pull is an important safety feature. The following list of drawbacks reflects only my own personal evaluation of the snub’s limitations as a self-dense tool and may not correspond to your own experience.

Small stocks make it hard to hold

Small sights makes it hard to aim well in less than optimal lighting conditions

Short sight radius aligns makes extreme range accuracy challenging

The high bore axis makes optimum recoil control challenging

A low available round count limits options for multiple target tactics

Longer list of possible malfunctions than occur with a semi-auto pistol

Majority of malfunction corrections are more time consuming than with a semi-auto

Small size combined with light weight makes it easier to forget and inadvertently carry it where prohibited
