I am thinking about buying a 320 X5 Legion. I was wondering if any 320 Full size magazine would fit, or do I have to just use the X5 legion magazines? I looked at Sigs website, but could not tell for sure. But I may not have looked in the right place. Thanks for any help.

You"ll need to use the 17 round X-5 Legion mags, the 21 round X-5 mags or get the appropriate base for your full-size mags. Standard mags won't work otherwise.

Great pistol BTW!! Love mine. You will get 3 mags with the pistol.

The magwell funnel is the deal-breaker.
Regular 320F 17rd mags would need their baseplates sanded/reshaped to get up into the funnel.
I ditched my regular baseplates and installed Legion baseplates.
So I run "Legionized" 17's and 2nd Gen 21's
That's all you need.

These are the 17rd baseplates Sig uses for the X5 Legion

Well, not exactly.
These are the baseplates SIG uses for the X-Five Legion :

They are made for SIG by Henning Group

This is is Henning Group proprietary version :


For a 17rd mag to work with the magwell funnel, you need this type of baseplate.
Or you can sand/file down the rounded, polymer baseplates to fit.
And 2nd generation 21rd mags will work with the magwell funnel as is.
