oh, and you might wanna consider dremeling a notch in your slide release so you can reassemble it without scratching the frame with it.
Worth doing to avoid the idiot scratch ( i was to late)

(mine isn't that bad, but still , it has a scratch).
Doing this will make the slide release ride the plunger instead of jumping off and scratching the frame..
You can push it straight down with this notch.
