In the US, 15 round mags are supplied (usually produced by Mec-Gar). As we are not permitted to pin mags in Canada. As a result, we are only able to supply 10 round mags (produced by Check Mate). The interweb will tell you the Check Mate mags are inferior, which is simply incorrect. All of our commercial demo mags are Check Mate, and we have not had a single mag issue throughout all of the demo and IPSC shoots we attend.
As to your serial number concerns; when the MK25 was released, Sig was using 226 frames with the "UU" prefix. These frames have been consumed, and Sig is now using "47A" as the serial prefix.
