THESE DO NOT FIT WITH THE CUSTOM WOOD FOREARM I HAVE LISTED
These bumper sleeves fit all versions of the 1377, 1322, PC77, 2289 and many other models that have a similar pump lever like the 760. Only one sleeve should be used positioned as shown in the photos. One sleeve will last for years for the average shooter, three are included as shown in the main photo. The forearm must be removed to install a sleeve.
These are made by cutting 3/8" ID x 1/2" OD vinyl tubing into 1/4" sections. This tubing is common and relatively easy to find.
