I graduated the NYPD police academy in the 80's and was issued a model 10, square butt, heavy barrel like practically everyone else. Along the way we transitioned over to 9mm and so I traded my revolver in for something I don't even remember.

Well, now, many years later, I regret that decision. I wish I had kept that gun as it was my first duty gun I carried at work. But, since I can't get my original gun back I've started buying any 1980's model 10's I can find in a effort to replicate exactly the one I carried when I worked.

But here's my problem ... mine had a smooth trigger and all the ones I find all have serrated triggers. Can anyone tell me why that is? Were smooth triggers only for NYPD or something? Because I never asked for it special and everyone I worked with had a smooth trigger too. That was the standard trigger for NYPD in the 80's. But yet it seems that I can't find any.

Second question: Is there any place where I can buy a smooth trigger so I can swap out the serrated one and replicate what I used to have?

If you are former LEO I will look and see if I still have a smooth .312 KLN type trigger for you.
No promises but If I find another one here I will
get back to you tonight or probably tomorrow.
Email me with your info and address....

My 10-10 has smooth trigger. It's been awhile seems I've read PD issued M10's with serrated or target triggers were causing blisters with double action shooting so S&W switched to smooth. I'm sure someone more knowledgeable will answer

OK Malloy,
After stepping over and disturbing my grumpy 130lb mastiff I found your trigger at my gun desk area. Email me your mailing address info and I will mail your trigger out tomorrow.
My gone Dad past 50s LEO so this ones for you
on me..
Randy..

Wow, that is awesome. Thank you sir.
PM sent.

I seem to remember that the transition from the grooved .265" service trigger to the smooth .312" combat trigger as standard was complete around 1983, probably with some overlap.

also a gunsmith can smooth a serrated trigger

Thanks all. Definitely a class act fleabus101. Thanks again sir.

So the trigger I am talking about is called a ".312 combat trigger"?

I prefer the idea of swapping out the serrated trigger with a smooth one rather than smoothing it out for 2 reasons.
1. Sounds like the smooth trigger is wider than the serrated, so it's not really the same thing.
2. I prefer to keep the parts that come with the gun so I can pass it on to someone else with all original parts if it I ever have to. If I smooth out the serrated one that is kinda permanent.

"So the trigger I am talking about is called a ".312 combat trigger"?"

I've always considered the smooth-faced triggers to be combat triggers based solely on the smooth face, regardless of width.

Generally, triggers that are grooved and of the narrowest width (.265") are "service triggers" (or standard width), whereas the wider triggers (such as the .400" or .500") are considered "target triggers." Using the "combat" moniker to describe the smooth-faced trigger helps to differentiate it from the other two.

I remember when the Smith & Wesson Model 19 Texas Ranger commemorative revolver same out in the mid 70's, that was the first time I became aware of the smooth-faced "combat" trigger of any kind. Later I added one to My Model 27-2 6". Still have that gun.

My memory is not perfect, but I believe that in the early eighties, a mirror-polished narrow trigger was in style for DA use. They were generally done by a gunsmith. Of course, preferences were an individual thing. I still like them best, although I can certainly tolerate a serrated trigger.

Got the trigger. Looks just like what I had on my old duty gun. Now I can replicate my service gun (that I should have never gotten rid of).
Thanks again bud. Very much appreciated. I can't thank you enough.
