Para mag mods?

[Grayfox]

I know, it ain't a Colt. But hopefully somebody here can help me.

When my son was in Iraq, he ordered two of the Para-ordinance SF-45-A pistols. These were a special offer to active military in Iraq and Afganistan.
Basicly they're really just showpieces, but we do shoot them occasionally.
The good news is they came with 5 magazines each. The bad news is that they're ten rounders. Normal capacity mags are expensive.
So my question is does anybody know how or even if these mags can be converted to standard capacity of 14 rounds?
I've taken them apart and have a few ideas, but I want to be sure before I go messin' around with them.
BTW: standard capacity mags are legal in my state.
Thanks for any help you can offer.

IIRC the ten rounders are actually shorter magazines with a plastic spacer to make them long enough to fit the gun. Because of that there is no practical way to add capacity. Ordered from Para the full capacity magazines are not that expensive last I checked make sure they know they are for military use. When you get them replace the springs with Wolf magazine springs and make sure there are no burrs on the plastic followers also sand down the seam at the rear inside of the mag if it is prominent.
