The discussion centers on the FN 510 and FN 545 pistols. The FN 545 is chambered in .45 caliber, while the FN 510 is a 10mm handgun. FN as a manufacturer is described as well known and frequently discussed, so the brand itself is not considered underrated. However, the specific FN 510 and FN 545 platforms are highlighted as deserving more attention. They are presented in contrast to a Tisas 9mm pistol and other 9mm handguns, setting up a comparison between these larger calibers and the more commonly discussed 9mm options.
The speaker emphasizes that the FN 510 and FN 545 are underrated largely because they are not chambered in 9mm. The point is made that many conversations in the handgun world focus on 9mm pistols, while 10mm and .45 caliber platforms receive less discussion. The FN 510 and FN 545 are cited as examples of pistols that should be talked about more often. The argument is that these calibers and platforms offer notable performance characteristics that are overlooked simply because they fall outside the dominant 9mm trend.
Before the FN 510 was released, a comparison was conducted on the channel featuring several 10mm handguns, described as involving around five or six different brands. That earlier test provided a baseline for how typical 10mm pistols handle and shoot. After that comparison, the FN 510 came out later, allowing it to be evaluated against the previously tested 10mm models. This sequence made the differences in shooting characteristics more apparent, since the performance of other 10mm handguns was still fresh in mind when the FN 510 was finally tried.
When the FN 510 was finally shot, its performance stood out compared to the other 10mm pistols previously tested. The pistol did not feel like a typical 10mm in recoil. Instead, its recoil impulse was described as closer to a .40 caliber handgun, making it an extremely controllable 10mm. The controllability was impressive enough that, at first, it even felt similar to some 9mm handguns. This contrasted with expectations for a 10mm pistol, which usually has more pronounced recoil. The FN 510 is mentioned alongside the Ax Delta 9mm, underscoring how its shooting characteristics invite comparison with softer-recoiling calibers.
