P-serial numbered guns (informal survey)

[Don Mills]

I wonder how many P numbered guns there are. I have P-420 and in talking with a knowledgeable source it is not known how many there were. They are supposedly the prototypes. The label in my case indicates 500 but I have read that there may have only been 5. Mine being P-420 could validate there being 500 or it could indicate the 4th as a 20 gauge. No real way of discerning other than asking others that have a P- numbered gun to indicate it’s number. If you have or know of one please consider sharing.

Here’s my 20 gauge P-420 and the label in the case. I have learned that this gun was sold to Cape Outfitters by Reagent Chemical originally.
