My Blue P-Rod.

I've installed the HDD in my P-Rod and also enlarged my transfer port to .125". The hammer stroke length has been backed out all the way and the hammer spring tension is set at 5 3/4 turns CW for all the way out. It's getting 24 shots at 16-19 fpe with a fill of 2800 psi. Ending psi is about 1200. As the pressure gets lower (below 1600 psi), the gun becomes louder. 3 full mags at very good power for such a compact little gun. Very accurate with the Beeman FTS.
