Didn't he sign an executive order banning the further import of surplus M1 Garands and M1 Carbines from South Korea, along with some others?
Yes AND no.
There was an EO issued, but contrary to what you may have heard, this EO doesn't actually say (cue Randy Travis) "Oh I'm gonna ban them for-ever, for-ever and ev-er amen..." or anything of the sort.
Executive Order 13637 redelegated some authority under the Arms Export Control Act (which also controls imports) to the Secretary of State, who simply was not going to authorize the import of the rifles. The AECA grants the President broad authority to control imports and exports of defense articles. IOW it's not truly a ban; as I understand it, the next SoS could simply change course and authorize the Garands to be imported, without the EO necessarily having to be revoked first.
AFAIK the only other EO that relates to firearms in any way was
Executive Order 13662, which imposed sanctions in early 2014 on various Russian people and companies in retaliation for Russia's participation in the Ukraine conflict. One of the sanctioned companies is the Kalashnikov Concern, so the EO resulted in a ban on Saiga rifles and shotguns. However, although this was characterized as an "AK-47" or "Russian firearms" ban in some reports, it's really not—it's a targeted ban on products under a particular corporate umbrella. Saiga fans remain nonplussed, but other Russian-made gun stuff remains commercially available.
AFAIK that's all of it.
Before someone else writes "Hey wait a minute, what about the crackdown on gun show sales...," the early 2016 "executive actions" regarding private sales (discussed
here and
here) did NOT involve an actual executive order, or anything else substantive, except for hiring new NICS examiners while enacting a widely anticipated NFA rule change. The rest was basically just a PR campaign.
