Thanks Fastbolt! I'm a hobbiest machinist at best. Not my trade by any means but I go slow and make conservative changes. I'm not so sure the 0.145" on center was the best of choices as the detent can be pushed out of it's bore towards the center of the mag catch but the action on the button is forcing it away from center line so I don't think there will be a penalty. I just didn't like the very tangential interference the 0.160" would give considering how wide the underside notch on the button has been cut by S&W.

That's so the mag catch has the proper movement to both secure and then release the mag with the intended range of movement of the mag catch nut in the appropriate position.
I'd say I've probably got more pre-load than S&W does then. I'm happy with the feel and the tension though, and the catch moves out of the way and into engagement without issue. I haven't tried it with a loaded mag shoved into the bottom of a slide just yet, I may end up with too much pre-load and have to drill a little deeper.

Didn't even think to call and ask, I couldn't imagine getting something like that out of them as just asking betrays what I am up to, drilling into their frame!
