I have found Wolf springs to be just close sized commercial springs thrown into a bag. Not identified and few fitting very well. There is no need to increase spring pressure and if your carbine fires OK, leave the original in place. GI springs are very high quality items. When installing the hammer spring, bring it in from the RIGHT side of the hammer, and it isn't difficult at all. I suspect that far from being custom made "stronger springs" they are just what is on hand and the ones that are too long are sold as stronger. And yes, I bought the whole $14 package from Midway. Used exactly one, the slide spring.

YEARS AGO BOUGHT 20,000 primers with a thicker cup made for semi auto ...Started reloading them in 380 auto no problem..... 9mm no problem....223 no problem. but misfires in the carbine...Second hit always fire....Always smack the operating rod to make sure it is in battery.... Do hammer springs in a carbine weaken?.....Charlie........PS .....yes...... I have always used small rifle primers in pistols applications with proven loads..... Have no problem with GI ball or reloads with regular CCI primers

Today's Post
This is from another thread and started all of this....I will check with wolfe and see about the slipshod...I may send back the wolfe and Get the longer GI spring specified in the manual and maybe the problem will go away with the correct GI spring....I order Wolfe automatically as I have never had any problems with them and have corrected many magazine problems using them.......(Later........ Just looked at wolf instructions which stated fitting must be done if needed....The ad on their site did not say that.....They even have a super dooper heavy spring.....I just got the regular, impossible to put in because it is too strong , spring ).........Thanks Charlie

Sometimes I can get the spring back in using the slide spring rod, but have had a couple slip off and go flying. In my cluttered work shed, they are sometimes gone forever. If it seems like a strong spring I put the TH in a vice (leather to protect it) and use a very small vice grip, maybe 4-5 in long, on end of the spring rod to slide it into place. Haven't lost one yet with that method and the vice grip doesn't mar the spring rod. I'm one of the elders and my hand strength is not as strong as it used to be, so this works for me.

things may go flying, but you will find them. A steady pull back and into the slot from the RIGHT.

I made me a tool years ago just for that job. I used a small screwdriver. Then narrowed part of the blade down to the size of the hole in the rod. But leave a stop on it so it won't go to far in to the hole. You have a lot more control then. I've used it to change lots of hammers and it still works great. The plunger rod almost never shoots across the room with it.

When I first started I stuck a few plungers in my walls. Using a punch or the guide rod that would slip out of the hole now and then. I saw this tool at the Pomona show 23 years ago, bought it for $10. Since using this, never had an issue. I'm sure it is after market. There is a similar looking tool, marked different, in "War Baby Comes Home" page 661.
