Is it safe to use +P and +P+ rated 9mm rounds in the new M1As?
shoot away................................ 8) woo, that was a glitch in the software..........an echo....... :lol: you will see small markings on your Steyr designating the proofs from the austrian manufacturer........I might be wrong, but I believe those markings are explained in the manual......... :?
+p yes. be carefull with +p+ it could be anything no standards for +p+
according to saami
standard 9mm p ammo 1.169 " Max Cartridge Overall Length max pressure 35,000psi
9mm +p 1.169" Max and 38,500psi max pressure
+p+ no standard it could be 38,501 or up in 40,000+psi or into rifle pressure range.
some +p+ ammo was made for subguns in arctic weather.
your steyr may handle it but it will accelerate wear.
any 'service' pistol in 9mm is going to be '+P'. NATO 9mm (read 'military' and who designs a service pistol without military contracts in mind?) as well as commercial european 9x19 ammo is going to be loaded to or very close to SAAMI +P pressures. NATO and european (C.I.P.) 9mm standard pressures are the eqivalent of SAAMI +P. american standard '9mm' is lower pressure.
your steyr was designed around and tested with '+P' equivalent ammo.
others are right about +P+, though, you have no idea as to what you're getting as there is no recognized/tested rating as +P+.
hotter ammo will of course wear out your pistol faster than mild loads, but that doesn't mean it wasn't designed to fire it.
