    I might as well start a thread on this since I will probably be doing one once they are available.

    I mentioned in the 1911 thread that Matrix Precision is working on a 80% receiver for P228. Matrix makes some very nice tools to finish 1911 80% receivers.

    Some additional information is here
    http://www.matrixprecisionparts.com/catalog/

    It sounds like they will be doing a pre-order soon for the receiver and are finishing the tools

    The parts kits are up as well

    more detail on pre-order

    The frame will be p228/p229 featuring the normal sized magwell not the new wider E2 magwell that takes the P229-1 mags. The material is 7075 aluminum. Pre-order price is $275 per frame, shipping is free

    Bolus, thanks for the information. I already have the parts needed but just have a couple of questions regarding the frame/receiver. Do you have an ETA for delivery on these and do you have a local source for anodizing them? Also, wondering (hoping) they also be available in steel? Thanks!

    They should be pretty close. the pre-orders seem to be going out since I see on some other forums that people are getting them. I think they were finalizing up the ATF determination as well.

    I dont know if they will be available in steel

    @Velzey on the forum here does all sort of coatings and his price for a pistol frame was quite reasonable when I asked him about this project

    when they become available they will be here:
    http://www.matrixprecisionparts.com/catalog/

    the jigs are showing up but selling out pretty quickly. He has plenty of German sig p228 kits (with the folded metal slide)

    Slightly off-topic, but... with all Matrix's listing of M1 Carbine parts and tools, does that mean an 80% version of those is up their sleeve too? :)

    damn, the adjuster knobs on the rail cutting tool have this insanely small thread pitch to control depth of cut precisely. IMG_3339.JPG

    rail is cut. problem is that the side is supposed to be a little loose but mine is cut perfect. not sure what to do now. I guess I will see how it goes with a good 1911 style fit.

    If it was me I would get some Clover lapping compound and work it in some by hand.

    I've been running 800 grit lapping compound between the slide and frame for a good 2 hours now and its glass smooth. but its not loose. perhaps it does not matter that much.
