- Shrewsbury's weapons, for the most part seem to be designed to be simple and inexpensive, featuring rugged styling, but deal less damage as a result in contrast to Vom Feuer's expensive, heavy-hitting weapons.
- According to the BAWSAQ description, Shrewsbury's weapons "won the West" during the 19th century. This echoes the basis of the Winchester rifle, which was used by the United States military between 1866 and the early-1900s and is often referred to as "The Gun that won the West".
- Despite being an American firearms company, most Shrewsbury products resemble foreign firearms.
