I have an FN 502, a Taurus TX22 and the Glock 44. The FN broke the first time I shot it. FN sent me a label, I returned the gun, they sent me a new gun and it's been flawless. The Glock 44 has worked just fine, too. The TX22 was far and away the least expensive and has been 100% reliable since day 1.
I'd recommend the Taurus over either of the others.
Or just get yourself a Mini-14 since it's steel and wood and not made by Mattel. Fuckin' plastic guns will kill your best friend, whose name you don't know...but then you can bitch about it for the next 50 years.
