identified a feeding problem that can occur with some of the
early production (2011) Px4 Compact pistols when fired with

after the pistol has been broken-in through repeated firing.
has developed a polished guide rod and recoil spring that corrects
the ammunition situation and is available for any customer
experiencing feeding problems.
