I've been thinking about ordering packers nickel mag catch and wanted to see how hard it would be to install. (haven't ordered it yet) So I took the plunge and started taking things apart. It was easy enough...the only problem I had was not winding the trigger bar spring all the way around to set the trigger forward. I had everything back in the grip and then realized the trigger wouldn't reset. Oops!!! Over all, pretty easy to do. I'm glad that I have a dental hook and some hemostats in my possession. They made life easier for sure!
