Anyone know where you can get some mag base plates for the 220 mags?  I got some 7 round mags and want to make them 8 rounds.

You can not convert them,  Just buy the new Stainlees Steel ones from the Factory.

Save some money and pick up the ACT-mags if you don't need to have Sig marked mags for duty.

Actually I have tried taking the base plates off an 8rn and put it on the 7rd and it worked.  I have plenty of mags, just trying to have them all the same number of rounds.

Working as able to load a round down the pipe, and then lock a fully loaded mag into the pistol?

Gotta ask since I just gave away all my old 7 rounders when I picked up new ACT 8 rounders to replace them.

Yep, loaded it fully and even shot with it.

I think you missed the question,  

With 8 rounds loaded, is there still enough room left in the mag for the top round to be compressed downward to allow the mag to be loaded in against a slide not locked back (read take the pistol to 8 rounds in the mag, and one in the chamber).

Also, since the base of the 8 rounder has a higher top lip, with the 8 round base installed on the 7 round factory mag only, is there still a little slop between the base and the bottom of the frame well for predictable mag loading (read my 7 rounders had the flat type steel bases).  If the area is too tight, then you can have a bad mag load (not locking in) just short of palm slapping the hell out of the bottom of the mag to issue it's seated/caught by the catch when reloading with the slide still locked home.
