You're going to want a high-quality Cyanoacrylate (CA) superglue for plastic-to-metal as opposed to your usual Tamiya cement for plastic-on-plastic adhesion, but be warned that a lot of the cheaper and fast-setting ones that you can find at a grocery store won't cut it, you'll need one that's higher quality and doesn't fog up the plastic and metal (which can ruin the finish on both). I'd recommend reading reviews online as there's still a ton of brands that'll work and it seems like everyone and their mothers like something different; there's a thread on just about every hobby forum or subreddit so you can check those out for more specific pointers. I prefer BSI Super-Gold Plus and have gotten great results with it but it's also kind of expensive and might be outside of the average builder's price range (I use it very infrequently so I can justify paying a little bit more if it stretches out a while, but if I was using it more I'd probably try to find something cheaper).
