Have two sks one used quite a bit and one I have never shot. The one I shoot regularly has a spring loaded firing pin the other does not. These things are Damn near half what I paid for gun. What is best source? I see a few places but sold out
 
Its a marketing gimmick. If it was a necessary part of the design they would have left it in after early 1950. Literally millions were made with no issue, and the only time there might be a slight issue is if you really don't do any maintenance on your rifle for a very long time. Even the AR-15 has a free floating firing pin but you don't see people running around selling spring loaded firing pins for it.
 
Early pin used a spring to prevent slam fires and the later used a lighter firing pin to do the same thing. Don't waist your money :)
 
the only time i had a slamfire was on a buddies sks whos firing pin channel was chocked full of rust. Have put several thousand rounds thru my own sks's with the free floating pins and never had an issue.
 
As the previous posts point out , I've owned quite a few SKS's over the last 30 years , and I've never had a problem . Keep them reasonably clean and they work . I think old man Simonov knew what he was doing when he designed the SKS .
 
just make sure the firing pin rattles around in the bolt when you shake it. If it rattles it is good to go. I literally only take my bolt apart once a year and give it a good clean. I just make sure it rattles every time I clean the gun. Never had a problem.
 
I had understood that the spring loaded firing was is there to make sure that the firing pin on a neglected/old/rusted rifle gets stuck in the retracted position instead of in the forward one.

Rather than preventing an inertial strike on a soft primer when the bolt comes forward into battery, I mean.

Can anyone confirm that? Or was it actually intended to hold back a freely moving pin against inertial forces?
 
The firing pin spring is there to return the firing pin to the rearward position. In the forward position you can experience out of battery or unintended discharges when chambering a round.

The Russians lightened the firing pin and eliminated the issue. It doesn't have enough mass to detonate the primer when chambering a round when it bounces.

If you neglected the bolt enough that the firing pin rusted into place, the firing pin spring would also have rusted out.
