Too many comments on the "downside" of moving LG forward so I'm leaving it in the hands of SIG's designers to have gotten it pretty close. I'm gonna have to learn to land her smoothly.

On float preparation, I will add a rear LG plate behind F-5 made of 1/4" ply with a couple of 6-32 blind nuts.

<edit> Hey, why not use the original LG plate? See pics. I used a chisel technique that Norm Abrahms would be proud of.

TTFN,
