Fusion 1911 Govt mainspring housing. by Randy, November 8, 2022
Little hesitant at first. But this part dropped in with no fitting. When changing out the mainspring, recommend having a vise or bench block. There's a bit too much tension on the spring to try and man handle it. Great product. I highly recommend it.
