I've searched and can't find a clear answer... Hoping someone can help...

I just purchased a pre-owned Model 10 FCP-SR (It's a first Gen from about 2012-2013). Doesn't look like Savage makes that specific rifle anymore and I'm looking to pick up at least one or two magazines as spares.

Was wondering if the newer plastic/metal FCP-SR magazines will fit? OR do I need to find some of the older style all metal (Which I think I see going for around 100 bucks).

Is there anything I should be aware of when purchasing even the older all steel mags?

TIA!
