"80%" Para?
1Without doing pre-purchase homework, I recently acquired an alloy ParaOrdnance P13 frame. The idea was to replace the P14 frame that has taken up residence ina MechTech CCU that works so well that I'm going to leave it there. I expected to do some machining (allegedly, the typical "80%" 1911 can be completed on a drill press with a the proper jig). My problem is that nearly every other frame comes with the slide release hole drilled. The mag release hole is there but it's cast in with no sign of having been machined. The slide release hole is where the dimensions are reference from on the 1911 and the tolerances are +/-.005 except for a few that are +.002, -.000. I'm not thrilled about attempting to locate remaining holes and surfaces from the unmachined and undersized mag release hole due to the problem of tolerance stacking. Sarco, where I assume this frame came from after Para's demise, knows nothing and has no Para specific prints or jigs. Does anyone have experience or insight into this? At present it appears that I have $100 worth of scrap aluminum.
