I think that you mean "pistol" instead of "positive". I have one of these and it is indeed a pistol. Was that the question?
"Police Positive" was a Colt trade name. If the revolver has a square grip it is probably the model known as the "new police" and if it has a rounded grip it is probably the model known as the civilian "new pocket". It's hard to believe but the little dinky .32 revolvers were the standard Police issue around the turn of the 20th century.
