LEO Marked S&W Semi-Autos

My first 3rd Gen was a 4506 from the Fresno Co. Sheriff Office. I purchased it from a Sgt. in my local PD, who had purchased it new(not issued) from the armorer at Fresno Co.,
when they were transitioning over to the TSW4566.



Following that was a 4006 CA State Parks, at the time only one known example was listed in the Standard Catalog of S&W, and it was the serial number of my gun.

And then a few years later, a boat load of them showed up on Gunbroker.

I lettered this pistol, it came back as the only such pistol in it's serial number range, and was shipped to the CA Department of Parks and Recreation,
Parks Service Division, in Sacramento, CA.

I have two KCPD 4026's, a Brooklyn Center police 6926, and two 1026's that are not marked but I believe to be Virginia State police. Pictured are the first three mentioned that are marked. I also have a 5926 that has the slide laser etched with the model number 5926 that is indicative of a LEO issued piece. Ironically the Brooklyn Center PD is where the female officer shot a man with her pistol and claimed she thought she was pulling her tazer.

The CHP 4006TSW definitely qualifies! I grabbed one years ago also before the price jump. They are incredible workhorses and great shooters.

They are really tough pistols. I was the LE rep when the CHP bought those pistols. Their criteria was that 3 test pistols had to go 40k rounds without a major component failure and that pistol had to fire a loaded round with an obstructed bore (stuck bullet/squib) with out disabling the gun. All the major pistol makers submitted guns for testing in .40S&W. The 4006 was the only pistol that successfully completed the testing protocol. Sig made it to around 10K then cracked a frame rail. The "G" company actually separated the slide from the frame during the plugged bore testing. They tested the 4013 the same way and they also passed. I have one of the 4013 test guns and it still shoots and function great.

What a neat story! Thanks for sharing.

The test with an obstructed bore is a real test for any firearm. Semi-auto pistol barrels may successfully contain the pressure, but will typically bulge and tie up the slide. Given the Glock's relatively small amount of steel in the slide's recoil impact area, I'm not surprised that there was a slide failure.

Not to drift on my own thread too much, I agree totally and I suspect this eventually led GLOCK to (slowly) redesign their .40s to the Gen5 revision with a much bulkier and stronger slide configuration.

And now that we’ve “sprung forward”, let’s see more of your Law Enforcement S&W semiautomatic pistols!

I have both a 4006 and a CHP 4006 TSW. I have shot our original duty Remington 155 grain .40 S&W and the last load issued the 180 grain HST .40 S&W and even though both are reliable the TSW eats both rounds like candy and has much better accuracy. Glad I bought it plus plenty of OEM magazines when they were released for sale to the public and relatively inexpensive
 
I have never heard of an obstructed bore test. But I do know that a couple 4006s from the LAFP Fire Marshalls failed an obstructed bore from a 9mm casing sitting in the barrel. Before LA had any .40 cal. Fire Marshalls fired qualification on our ranges. Unfortunately, twice I remember them accidently loading a 9mm in the mix somehow. The 9 would fire, the bullet rattle down the barrel, but the casing would not extract and would be pushed up into the barrel by the next round. When that round fired the casing would protrude from the muzzle, then split and flower out. The barrel would be bulged and you couldn't open the slide totally. We had the same thing happen with several S/W .45 pistols after we approved .40 cal weapons. Every one I ever encountered, the casing would be stuck at the muzzle, split up and flowered out just as neat as you please.

The fix is to carefully cut the sections of the barrel you can get to with a foredom tool/Dremel and a small cutting wheel until you can get the slide off. Once that is done, we replaced the barrels and the guns were fine.


Modern LAPD did not mark their issue handguns. With just a couple modern types like SWATS 1911, SIS's guns and maybe some of the other private purchase guns since I left. Then marked by the serial number from the company LAPD... or SWAT....Any weapon with non-factory markings had to be approved by Command Staff. Like the model 68s or SIS's guns. I am sure some private purchase guns were marked after being registered by the armory, but if discovered would be removed from your weapon card.

Before I retired, I secured a copy of my weapons card to verify what was carried and also receipts from the city for the issued guns, that I was allowed to purchase upon retirement. In case, I ever sold them, maybe that would add to their value. (sadly, no children, one niece).

Also, the only 3rd gen S/Ws ever issued by the dept would be SIS's 645s/4506/66/16s. and
There was 1, 3913 issued to a female LT. who complained that her 92fs weight was causing a bad back and threatened a lawsuit. She was well connected (probably because of her private purchase endowments) which I am sure didn't help her back. But we were ordered to issue her one as a primary duty weapon, even though it did not have a 4" barrel.

Then there was a dubious experiment (due to some Command Staff request/order) where we issued 12-15 3906s to females in a recruit class, due to a few shooting failures in the academy. Where it was proposed that the Beretta 92's large gripframe or reach to the trigger was the issue.

These were issued with quad pouches, so the amount of ammunition carried was about the same. We did an audit several years later and about 8-9 of them had been turned in upon person leaving the department and only one of the others was still being carried/qualified with. The others had transitioned to private purchase guns, probably a glock since they were then approved.
The turned in guns were later sold to a LE dealer in SoCal, something that usually never happens. Of course, by the time I found out about it, they were all sold. They were not marked in any way, but you could have proved they were shipped to LAPD from S/W.

A month or so after I moved to TX., I went to a local hardware store/gunshop and picked up this little beauty for about 350 out the door. I put a hammer, and a trigger play spring in it. I only have 2 .40s, a Vertec and this one, that is a heck of a gun.

Here is my 1076 I picked up just shy of two years ago. I am told by a fellow forum member that it shipped to the Auburn Hills, Mich. PD in September, ‘91.

Next up is this pair of 6904 and 5904. I understand these to be rack marked from Illinois State Police issuance in 1989 - 1990.
Don't believe those are ISP. We never used any "rack numbers". The only vintage guns we issued that had an extra number stamping was the 39, not on 39-2. That was an inventory number and that marking stopped in the early 1970s. Inventory was done by serial numbers. Even then the extra numbers didn't look like yours.
Neither my 5904 nor 6904 were stamped. I inspected a lot of 5904/6904. Never saw any of ours with extra number stampings.
Don't recall ever seeing any of our 5904s or 6904 with the square trigger guards.
There are bogus S&Ws out there being marketed as ISP guns, including shotguns. I've seen 2 5904s that were stamped that the seller claimed were ISP guns. They were easily identified as counterfeits by anyone who knew legit ISP stamped guns. Who ever stamped them thought they were duplicating the stamping used in the early 39 and they did it wrong.

Neither of my 3rd Gen pistols, 4566 & 4006, have PD or government marking but the 4006 has the last four of the serial number marked on the slide which makes me think that the previous owner had multiples of the pistol.
