G42 Reassembly

679 Views 6 Replies 6 Participants Last post by  Mike-M
Just picked up me new 42 and put 200 rounds through. I did a complete teardown and cleaned her up. I have a couple of questions on the reassembly. 1)the plastic piece that resides inside the trigger spring has a slanted side and a flat side. Mine has the flat side up. Is that correct. 2) are the slide lock spring and the firing pin safety spring the exact same spring or do I need to keep track of which one goes where. 3)Does the slide lock notch face the rear like it's big brothers.
I always appreciate the help.

Note that the groove at the top of the Slide Lock engages a similar groove on the bottom front of the barrel lug. If the Slide Lock's groove is facing forward, the barrel lug's groove can never fit into the Slide Lock groove. Results:

1. The impact of the barrel lug with each shot will eventually push the Slide Lock downward, which can allow the entire slide assembly to propel itself forward off of the frame if the firing pin lug rides over the trigger bar cruciform. (Fortunately, that usually doesn't happen and the slide assembly stays on.)

2. Until that happens, the barrel lug groove finds no Slide Lock groove to engage. That reduces the tightness of action lockup in battery and may increase shot dispersion.

When one understands the function of each part, there will be no future uncertainty of how, why, and when they fit together. :)
