Got mine in from Reed's. OEM Tanfoglio part. Came with the disclaimer as above.

I was able to load full 12 rounds into the compact mags, even with dirty old brass cased reloads. Was a little stiff, but they went in. After first couple full loading/unloading I put some Rem oil on the four sides of the follower and used some nickel plated cases. Went in nice and smooth, but still stiff.

They fed just fine.

Hope this isn't an anomaly. I plan to get a few more while they're available.
