Generally I stay away from +p however this time is different (famous last words).
9mm 124gr plated RN for home defense, The firearm is a rugar security-9 semi auto. On pg 13 of the OEM supplied literature it's stated that +p+ ammunition should not be used. A standard load using alliant red dot at 4.6gr provides a chamber pressure of 33k. Per SAAMI the max psi for a 9mm is 35k, This leaves room to sneek up on max/+p. I was thinking +p and +p+ were close to the same in terms of PSI, Meaning a no go on one is a no go on both, Is this correct? I am having trouble finding definitive info. I see a lot of numbers in the 38.5k range which seems extremely high. Thoughts?
