I'm interested in a 5.7 pistol as a bugout bag type gun because it's ammo is roughly half the weight of 9mm, yet far more capable and reliable than 22LR or 22WMR. Lots of people are saying the Ruger is better than the FN 5.7 in spite of being cheaper. I handled the Ruger at a store and noted that the trigger was really good, at least compared to the Glocks I've been shooting for years. The only other 5.7s I'm aware of are Keltec and S&W, both companies that I'm suspicious of. Should I buy the Ruger or something else for this cartridge?
