OK, final shopping cart from HKwebshop. I am going to order the hammer sping and TRS from somewhere else to make sure I get the lighter version. Can't find the recoil springs without the whole assembly either, so I think all of this will come from HKparts.net. High pricing vs the webshop, but not buying the whole recoil assembly will even it out. Bought 3 LE marked mags from arfcom for $40 delivered and one unmarked for $30. Had 3 mags with the gun. So $70 for 4 more mags. Added mag springs from the webshop. At $3 each I figured its worth it considering most of them are for sure from 94-04. I'll post the partsnet cart when I order it. Will post totals for everything and do some reliability testing when it's done. 7 mags is a little overboard, but I started shooting in the Clinton era, and this could end up in a USPSA match.
