It is estimated that 3,777 examples of the "Pre-Model 37" were manufactured with an alloy cylinder with reported serial numbers ranging up to 44577. The majority of these were produced in the round-butt configuration. While the use of aluminum alloy permitted the revolver to weigh in at a mere 10 3/4 ounces, these cylinders were known to develop cracks during use, and resulted in Smith & Wesson reverting to a steel cylinder on further production.

WARNING: Aluminum cylinder variants are unsafe to fire with full power ammunition and should not be fired.
