If you purchased the P365X, or P365XL in a 10 round magazine limit state, you should know that the10 round magazine that came with or sold for the 365XL, or 365X could come in two different and incompatible mag tube lengths now. It may be the same physical size as a 12 round mag tube for the P365XL, or P365X, or use the shorter 10 rnd mag tube. The original design uses the longer 12 rnd mag tube and has dimples on both sides of the mag tube stopping the extra two rounds from entering the mag. You'll need to use the 12 rnd XL mag basepads on our site for those.
Recently Sig changed the design of the P365X, or P365XL 10 rnd mags to use the shorter standard P365 10 rnd mag tubes with a basepad similar to our 10-XL conversion basepads, that makes the mag long enough to fit in the XL grip module.
If you have one of those mags, please see the 10-XL Conversion basepads, of which there are four lengths, flush/flat, Pro Ledge, Large Pro Ledge, and Extended pro ledge.

Please only purchase compatible basepads for your 10 round limited XL magazine. Specific magazine compatibility is stated on each of the product pages. Please carefully check compatibility before purchase to avoid having to do a return. We only allow returns of unopened products.
If you have not yet purchased, or are about to purchase 10 rnd XL compatible mags, Sig has in the past not specifically labeled parts that have multiple different designs, and has shipped them with the same part number, and packaging, though they are different.
We suggest you verify with the place, or person you are purchasing your mags, if they are short 10 rnd, or longer 12 rnd dimpled mag tubes, especially if you already have some of our basepads for the XL grip.
