Got the package from Tripp. Faaast shipping.
I've already installed the first spring/ follower upgrade.
The Tripp spring is about an inch and a half longer and is significantly stiffer. The Tripp follower is also a robust affair. Some instructions would have been nice. Tripp obviously figured that any moron could change a mag spring and follower.
He was wrong.
Once I tried every conceivable incorrect approach, it only took me a couple of minutes, a punch, an eraser-tipped pencil, several Band-aides, and an Imperial gallon of Bactine to effect the change.
Looks good. Now for some range time to see how my Smidt likes the new configuration.
