Triple K mags are strictly hit or miss.
I purchased some .380 Jo-Lo-Ar mags from
www.ammoclip.com that were solidly constructed and very well made, and was totally surprised when they told me they were Triple Ks. Edit: I just looked and they don't have Bayard mags.
On the other hand, most of the Triple Ks that I (and pretty much everyone else) are familiar with are made from razor thin sheet metal with crude aluminum followers that look like they were hacked out by a beaver. These are/were made in Mexico and usually have about a 100% failure rate.
I do see Bayard mags come up for sale on eBay every once in a while, but they are usually for the .32ACP, which is what I have. You might want to add a search for a .25 on eBay. Gunbroker is another place to find stuff, but it is usually grossly overpriced. (Example: Some clown from Poland has an original on GB right now for a "mere" $180.00

)
BTW: If you do field strip your new toy, be sure to look inside at the buffer spring that's installed at the end of the recoil spring tunnel. That's how they managed to achieve such small size.
