For those doubting the existence of +P-rated .32ACP ammunition, take a look at the Buffalo Bore line.
I don't know the Buffalo Bore practice, but be aware that +P is a SAAMI designation, and as such, a +P .32 ACP would be listed in the SAAMI standards. So is there a SAAMI spec for +P .32 ACP? Or is Buffalo Bore simply raising velocity slightly (but still keeping it within normal SAAMI pressure limits) and just using +P as advertising puffery? I don't have a copy of the latest SAAMI specs, but there is no +P .32 ACP shown in my older set, which is from about 2005. Unless it is in SAAMI, there is no official +P .32 ACP. Of course, any manufacurer can load any cartridge to whatever pressure it wants and call it whatever it wants, as SAAMI is a set of voluntary standards, not a law. They could even call it ++P++. But if Buffalo Bore is doing this, they run a great legal liability risk if a pistol blows up and hurts or kills someone while using their ammunition (by the way, +P+ is NOT recognized by SAAMI).
I agree with the others: Why use over-pressure ammo in an old gun? The 1903 is a beautiful piece that can still be well appreciated today, but wouldn't put modern gasoline in an old car or drive it as I would drive a new car.
Don't do it, man.
Get a bigger gun.
I shoot my own low powered handloads in my1903, wouldn't shoot the modern ammo.
thank you all who posted answers, I do appreciate it. Based on your answers, I am not going to try the Buffalo Bore +p .32 ammo in my .32 1903 Hammerless.
Now I am just regretting that I already bought 2 boxes or 40 rounds of the ammo already. It cost me about $25 per box. Money down the drain 'cause I don't plan on buying any modern .32 auto. unless I get rich or something, I already own a .1911 .45, a S&W .357 mag and a Ruger snub nose .38.
The gun was designed to the old pressure, you want a cannon, buy a cannon, case closed. Buy some REM Silvertips and call it a day but I can tell you from experience you still got nothin'. A good fireplace poker is an even match for a 32, the poker probably has more fist shot stops.
I got a fever, and the only cure is more guns.
