We don’t know much about the background of the Ruger 57 yet because it hasn’t been fully released yet.
However, we can give some background on the 5.7x28mm round and make some basic comparisons to the FN 5.7 thanks to the below leaked pictures.
The 5.7x28mm cartridge was developed by Fabrique Nationale (FN) for their P90 rifle and their Five-Seven pistol. The 5.7x28mm cartridge, which looks like a mini small-bore rifle cartridge, is effectively just that, but it was designed for a handgun and a short barreled rifle. It is a high-velocity small caliber bottle-necked centerfire cartridge.
RUGER 57 SPECS
The 5.7x28mm cartridge, and the firearms that fire it (previously only the Five-Seven pistol, the FN P90, and some aftermarket AR conversions) have a bit of a cult, if not obscure, following.
Personally, I’ve never warmed up to the round, but, who knows?
The idea behind the cartridge is to give armor-piercing firepower out of a small platform. FN succeeded in this endeavor, however, I haven’t seen much defensive use beyond that.
However, if you compare it to something like the 17 HMR, now you’ve got something interesting. Perhaps the Ruger 57 would be an interesting trail-gun?
All we know about the Ruger 57 so far is what we know from pictures and some leaked information.
The Ruger 57 seems to be a polymer lower with a steel slide with front cocking serrations with a Glock-like trigger safety. Also, the 57 by Ruger appears to have an optic plate on top of the slide – it does not look well conceived based on the picture. Also, the Ruger57 shown has a (giant) thumb safety and adjustable sights.
Here are some pictures to help you compare it to the only other 5.7x28mm pistol we know of, the FN Five-Seven.
