Brazos SC Shooter Posted May 4, 2023 Share Posted May 4, 2023 I am shooting my first major match with my 320 Max this weekend. The way I read the rule book Appendix D7 Carry Optics 22.3, which says no "No OFM or aftermarket external magwells". I interpret this to mean I must remove the small additional metal piece that was on the gun from the factory to avoid being moved to Open, right?

Unibrain Posted May 4, 2023 Share Posted May 4, 2023 Correct. If you don't have a mag gauge(1) be sure to have chrono do a curtesy check. Some 320 factory mags and some extensions don't fit the gauge! (1) If you don't have one they are less than $30. Link to comment Share on other sites More sharing options...
RJH Posted May 4, 2023 Share Posted May 4, 2023 (edited) You can always leave the magwell on it and shoot limited optics. The mags might still be an issue though Edited to add: assuming the major you're going to allows limited optics Edited May 4, 2023 by RJH Link to comment Share on other sites More sharing options...

If shooting CO, the factory MAX magwell must be removed. I just put mine back on and going to shoot Limited Optics till my LO gun arrives! Link to comment Share on other sites More sharing options...
Brazos SC Shooter Posted May 5, 2023 Author Share Posted May 5, 2023 Thanks for the confirmation from everyone. The match does have Limited Optics so I might just change my class when I check in. I am not running mag extensions so I hope that works. Link to comment Share on other sites More sharing options...
Boomstick303 Posted May 5, 2023 Share Posted May 5, 2023 Make sure your mags pass a gage before you start shooting. Link to comment Share on other sites More sharing options...

I will see if I can get a courtesy check as recommended. I am running factory mags with the smallest Taran basepad. Link to comment Share on other sites More sharing options...
Boomstick303 Posted May 5, 2023 Share Posted May 5, 2023 (edited) The 21 round mags I assume. Not all of the mags pass automatically. The most efficient way to fix the is smash the groves that fit into the base pad slightly. Many have had luck doing this. The other way is to file or sand the rear part of the feed lips ever so slightly. The ones that fail barely fail, so the mags do not need much work to pass. If you use a file make sure it is a really fine file. Do not remove more material than you need to. Edited May 5, 2023 by Boomstick303 Link to comment Share on other sites More sharing options...

If you're using the 21 round mags they don't all fit the gauge. It's a matter of fractions of a millimeter but I have several and a few didn't quite rest on the back pads as required. The second pic below is an example that doesn't pass gauge and it's an OEM 21 round M18. This is using an official EGW gauge. https://imgur.com/a/ZqhF4ap Link to comment Share on other sites More sharing options...
Hoops Posted April 15 Share Posted April 15 This was from a post last year. I want to buy a Sig MAX 9 for Carry Optics. I see that the magwell must be removed. Question: Is the magwell attached with set screws making it an easy process to take off and add back on? If asked and answered, sorry.....I just didn't see it.

Thanks, @Hoops Just sold my MAXX here in the classifieds...... But to answer your question, yes there is a recessed set screw on the rear that allows easy magwell removal. Good luck with your MAXX!

Thanks, As previously answered by Hogrider, it is pretty easy to take on and off. Nationals had the provisional, now permanent Limited Optics category, which doesn't require the removal of the magwell. All things being equal, I prefer to leave it on and run in Limited Optics.
