Going to try this 9x1x60 mm spring https://www.amazon.com/dp/B09LV363YZ

2-3 week ship time tho. SAE equivalent or cutting down a long spring might be quicker. 60mm is unusually long, most options end at 50mm.

2-3 week I've found usually means shipping from China and is cheaper on AliExpress.

There are a lot of various springs on AliExpress. I have a lot of poppet hammer springs, AirForce hammer springs and my collection of Hatsan semiauto return springs.
