Sooo... watching a few vids on the old YouTube. It looks as if some people are using the FX PP AND an external PP?? Are my eyes seeing this right? If so what benefits does this bring?
Minimal benefit. PP already adds more than enough air for even the 35 cal.
Until the .357 produces at least 250 ft-lb at the muzzle then there is ALWAYS more need for air!![]()
