Are there any grease guns made in the US?
I highly doubt it, The USA made Stewart-Warner Alemite's were the gold standard for many years.....Then they got bought & sold a few times & production moved overseas.
The silver gun I have pictured got bought in the late 80's at a farm/ranch/feed store.....It's identical to my SW Alemite A550 except for the quick release bleeder, Probably made by SW for private label branding.
A new offshore Lincoln, Alemite, Or Macnaught will serve you well for many years as it will most likely see light duty? HeII.....I don't use my grease guns like I used too!
