The typical sausage pack in the U.S. is a 20 oz (600ml) tube marketed as an economical delivery system in large scale jobs.  We have seen substantial growth in our sales of sausage guns over the past couple of years, so either we're getting better at our marketing or the sausage pack is becoming more mainstream.

 

Our guns come in two flavors: metal and composite.  The price is comparable on both, so in many ways it comes down to personal choice.
