This compact comes in either 10 rd or 12 rd mags. Is there a real difference in dimensions in Mags?

I assume either 10 rd or 12 rd can be used in the same gun. Is the differences just the spring? Finger rest on 12 rd will not work on a 10 rd mag. This implies that base is different on these two mags. I have 10 rd mags and would like to use a 12 rd as a spare.

comment please.

I would think they should work. The 10rd should just have a different follower than the 12. Worst case you can call or email s&w customer support, I have utilized them a few times and they are very helpful

They have different followers I believe. Either that or the base plate has some sort of plug to reduce capacity. I've honestly never looked at reduced cap mags. Both will work fine in your gun.

This. They are both the same except the internals. They are this way due to the restrictions of some states. I've used both 10s and 12s in mine in the past. Thanks.

The 10 or the 12 will work in the gun. The 10 is the 12 with some sort restrictor to limit the capacity. Mine actually came with a 12 and a 17. I think the only ones that are not interchangeable are the ones for the shield.
