I purchased the Black, Medium trigger via Brownell's last year.
I had purchased a new Colt Combat Unit 1911 rail gun & it came with a Long competition style adjustable trigger. The trigger was a bit of a reach and I needed a medium. So I purchased this one.
Consulting the book The M1911 Complete Assembly Guide I installed it. A perfect fit. Later I lightly polished the top and bottom of the shoe, slicking it up. I put this Colt and Harrison's trigger through a torture test I call the Okefenokee Baptism. Water, Sand, Mud. Though 100% function was not achieved, I am still determined that it will. Will try the Gunfighter lub next.
Thanks for a great product.
PS when I discovered this Item was made just down the road, here in Georgia I shouted with Pride.
