Yes. Trump is not actually friendly to gun rights.
If he was, he'd be pushing to get the Hearing Protection Act (HR 404) and the Stop Harassing Owners of Rifles Today (HR 2395) out of committee and to the floor for a vote.
Biden wasn't friendly to gun rights either. I don't think most politicians are friendly to gun rights, since if they actually managed to expand them to what they should be, they wouldn't have any major issue remaining to campaign on.
Do you have evidence to support that? Because AFAIK, the Glocks made both in the US and Austria have exactly the same design. OTOH, in most of Europe, it's very difficult to get the appropriate license for a handgun, so it's largely irrelevant.
