Tomorrow I'll receive a Colt Pocket Positive from 1915 that I've purchased using my C&R.
It appears to be in great shape, including the nickel plating. I'll post pictures when I receive it.
I understand it's chambered for the .32 Colt New Police which is a .32 S&W Long.
Are these revolvers up to the use of modern ammunition? I have a couple hundred rounds of .32 S&W Long and about the same amount of .32 S&W (short).
I have a couple of New Service Revolvers from that time period and yes, you can fire standard velocity smokeless ammunition, but....
My New Service revolvers are of dead soft metals, not heat treated. I remember finding a citation when Colt and S&W started heat treating things, like cylinders, frames, and what I remember it is after this period. Your Police Positive is made of the same, crappy WW1 metals, not heat treated, and therefore, you must not in any way attempt to hot load your 32 S&W Longs.
I have a S&W in 32 S&W Long, and I made the assumption that Aquila had pressure gauges and loaded the ammunition I purchased to pressures safe for these old pistols. I am going to say, based on velocity (which we know is not pressure) to keep loads around 2.0 grains Bullseye with a 100 grain lead bullet. That will be close in velocity, and I assume pressure, to the Aquila ammunition. I show a slighter higher load for comparison.
