I picked up a couple Argentine Ballester-Molinas recently as they do show up once in a while and these were in pretty good condition.
Ballester-Molina #1
Ballester-Molina #2
They are a bit heavy (all steel) but feel good in the hand. Good thing that some parts (barrel, magazines, etc.) interchange with the 1911 Colt guns. They make nice C&R additions.
Congratuations on getting a couple of the BM's, you have a nice looking pair of Ballester Molina's, IMO they are nice pistols, I use GI 7rd mags in mine, however I do have one of the original mags w/matching # on the base plate. T
