Sig P320 / P250 Magazine Floor Plate Updates

Sig just started shipping the new X5 and X-Carry grip shells. We ran a pre-order and started filling those orders last week. A few customers received the grip shells and reached out to us because their 21rd (MAG-MOD-F-9-21) and 17rd (MAG-MOD-F-9-17) magazines wouldn't fit / lock into the grip shells. We did some checking and realized that Sig is updating the magazine floor plates making the tabs on the sides of the floor plates thinner. The magazines still use the same part numbers as the old magazines so it is important to pay attention to the floor plate if you're going to be using the mags in a new X5 or X-Carry grip shell. Below are photos of the different magazines for comparison. The most recent iteration has the round Sig logo with the squared (instead of round) cutout for the the magazine floorplate insert. The mag on the left below (from my P250) is an older MAG-MOD-F-9-17. The middle is the "first gen" 21rd (MAG-MOD-F-9-21) and the one on the right is the newer "second gen" 21rd mag (MAG-MOD-F-9-21). Note that we're calling those first and second gen but we don't believe Sig is officially giving them generation designations. The magazine below is the newer style MAG-MOD-F-9-17 with updated design. Behind it is the the older mag. Below is the older style magazine in the X-Carry grip shell. It doesn't seat. Behind it you see the newer style mag with updated floor plate. Below on the left is the older style mag and the newer style mag on the right.

Below is the newer 21rd mag with the newer one on the right. Newer mag in the grip on the right and older mag behind on the left. For further comparison, below is a photo of an original P250 magazine floor plate (no tabs). We checked and mags with these floor plates also do not work in the new X-Carry and X-5 grip shells. In the last week we have received a few MAG-MOD-F-9-17 and MAG-MOD-F-43-14 mags and they have the updated floor plates but the part numbers didn't change so it will make differentiating mixed inventory a bit difficult.
