Hi, I wasn't sure which sub-forum was most appropriate but this seems to be a reasonable option.
I've completed 3 lower builds (an SL-9, an Orca, and most recently an SL-15) and have had a recurring issue.
For all three builds when the hammer is in the un-cocked position, the rear-most part of the trigger body raises up so that (when viewed through the safety selector hole (obviously with the safety removed)), the edge of the trigger body partially obstructs the safety selector hole. When the hammer is cocked, the rear part of the trigger then sits properly on the floor of the lower removing the obstruction.
This has two practical effects: 1) the safety can only be inserted with the hammer cocked (which isn't such a big deal) but more importantly, 2) the safety selector cannot be moved with the hammer un-cocked due to friction.
I've followed the videos closely during each build but I may be missing an obvious step- but clearly a safety that can only be engaged once the hammer is cocked is no bueno.
Once the trigger mod (for the SS) is done, the safety can be inserted and moved with an un-cocked hammer but it feels like I'm cheating by doing this when using a standard safety selector (and all of the build vids use an unmodified trigger so I feel like I must be doing something wrong).
I welcome anyone's feedback on this issue.
Thanks!
