DC was registering guns with "multiple calibers" in the caliber field even before dropping in 2012 the portion of code stating you could only posses ammo of the registered caliber.
I think it was neither H2 or H3 but rather threat of suit that changed that. H2 was a loss and h3 was 2015, the prohibition on possessing ammo other than your registration caliber was dropped in 2012 as a result of suit threat, not a specific case as far as I recall. Possessing some ammo before you had a registered gun was now allowed if engaged in training at that time as well.
So for the OP, it is not caliber of ammo possessed that is the issue, it is the accuracy of your registration card, which, under DC code, is explicitly your responsibility to ensure, not MPS's responsivity. Your card must be accurate and complete to be valid.
If you have caliber exchange kit, eg common .22 slide and mags available on dozens of makes of 9 or 40 guns, or as I do, a P320 with both 9 and 40 kit, email Hall and ask to be sent new reg that states "multiple caliber."
Also don't assume having the alternate caliber kit and not assembled in DC is ok. As the c"onstructive possession" case law is federal, meaning anywhere in the US having something that can be readily assembled at same address means you are presumed to be controlled by the net assembly -- simply having your caliber change kit at same address is "constructive possession" and the registrant, not MPD, is responsible for insuring that the registration card is accurate. It is best to request multiple caliber designation or if they are doing it, "9mm and .22 cal"
Make the request and let us know what they say. Ask toi speak to a supervisor if you get hit withresistance since the lower eschelon in that office is not exactly informed.
