Rosco,
Those Jay-Pee rigs were/are real dogs.
MY father (ret'd NYPD) used one for years.His had the pen

IIRC, It did have a "trick" anti-snatch retention device-a leather wedge that blocked the frame when inserted that was not apparent from the outside. Kind of the first "safety" holster.
Back in the day, NYPD guys also bought a bunch of IWB (for m-36's and D frames)holsters made by an outfit called STEIN. Not bad rigs-hard molded and well made.
The muy savvy rig when my dad went through the Academy(late 60's) was a Heavy Barrel M-10, gunsmith-installed target trigger and target hammer, and Mershon (pre-pachmayr) grips. The TT and TH came in handy on the single action, 25 yard stage of the qualification. Action tuning usually wasn't necessary on those old rev's-they were smooth.
I used to rag my dad about the NYPD hardware, RN bullets, etc.
It was more often street smarts, than gear that enabled the NYPD cops to survive a bad tour in the old days. During the 60's, and 70's and most of the 80's, NYPD was very understaffed and most car and foot patrols were solo. All the firepower you had was your M-10 (or PP, or SS), 18 rounds of LRN, a M-36 or DS, and maybe an unauthorized Backup. Favorites in the 70's and 80's were HS .22 mag derringers (cause they worked), or seecamp .25 autos (cause they worked).
Gun-guys carried a lot of unauthorized gear, depending on who they worked for. My dad sometimes toted a Series 70, nickel GM-the gun that spawned my love for the 1911, as "backup" to his m-36 when "off-duty". A Colt python 2.5" or M-19 was also a fave.
Gun-Guys who worked in BAAAAAAD neighborhoods (most of NYC at the time) carried unauthorized hollowpoints (usually super-vel), or even hot reloads. A 110gr JHP at 1100-1200 was popular.
I remember when the Safariland-Rogers speedloaders came out. It was like Christmas to Dad.
The old man could/and can still pop the top off a soda bottle at 10-15 yards, DA, at will with a fixed sight .38 revolver.
But now, he carries a G-19, sw-M49 or a 1911 as a civvie.
