k-38 trigger push
Sorry, I just realized I put this in the wrong "era". The question remains the same however....
I have a k-38 early 50's vintage.
The trigger pull is very light and crisp, best I have on any revolver. When the gun goes off, the spring pushing the trigger back to reset feels super strong. I mean it really pops the trigger forward during the recoil to the point that I am not sure I could hold it back if I really tried too.
I am guessing they reduced the trigger spring but left the return spring full strength?

What you have is getting very close to, or may have reached, a condition known as "Push-off". Cock the gun, push forward on the hammer spur and the hammer will probably fall. It should be addressed as soon as possible as it only get worse, and may not be repairable by then. Do a search for push-off on this forum and you will find several posts on how to repair it.
It is not possible to "replace the trigger spring" while leaving the "return spring" as-is, since it is the same spring known as the "rebound spring".

You're talking about the rebound spring and yes , they are frequently heavy. Wolff sells rebound springs in various weights.

Thank you for the tips.
The trigger pull is very, very light. Someone clearly polished it for target work.
I have some rudimentary gunsmithing skills, and already tried cocking and pushing forward on the hammer. It is solid but not to say it can't wear over more shooting.
I need to look over my new S&W shop manual the cat bought me for Christmas. My GF and I don't exchange presents, but the cat always seems to know what I need. Don't know how he wraps the presents without an opposible thumb, but that's another story.
I was assuming it was like my Ruger GP 100 with a trigger spring and a return spring. I have replaced them with Wolf springs and it helped that gun a lot.

Check the mainspring tension screw in the front of the grip frame. It should be tight. Sounds like someone may have loosened it up or possibly ground it shorter to lighten the pull -- never a good idea.

The condition you describe occurs when the trigger pull is reduced to a point at or below the pressure of the rebound spring. If there's no pushoff condition, you've lucked out, but there still exists a real danger of unintended discharge. Best to see the smith and think about replacing some parts. Just my $.02 worth.
