## Most critical reviews (6 lowest-rated)

### 5/5 — Great App, simple and Powerful

*2016-02-09, version 1.0*

It is difficult to make a gun selection with so many options available, many times choice is heavily influenced by tradition or what has been normally done in this field. This app helps challenge that perception and provide quantitative feedback as to what would a different option do in this field.
