Oh yeah got the Meprolight night sights on the way I talked to Bill Springfield said he can do the trigger job for less and have a better trigger so I am going that route as well MikeOD here is where I got my barrel. https://www.gunsamerica.com/99317546...cap-costs-.htm you are not going to get a better deal!
Congrats. Internally, the early model USPs have a control lever and catch that are actually on connected. In the later production, those became two separate items. In order to use a match trigger kit, you'll need to purchase the separate control lever and catch, along with the match trigger kit.
If you need help with the install, give me a shout via the website.
