Hello All:
It has been suggested that I run a muffler on my HP .40 that is mounted upright on my Mustunt II. In my junk box I found a chip muffler that came with a Brodak .25 that I purchased years ago. I have noticed that both the Brodak .25 and the Brodak .40 use the same muffler, could I use this muffler on my HP .40? Everything lines up such as the screw holes, exhaust port and the screw threads. Will this muffler be good for the HP or should I modify it by opening the holes or other mods?
Tia,
Frank
