Personally I wouldn't want a gun that would FALL APART under any kind of use!
But like the man said, you gotta give more info/ pictures if you want help.
junk in-- junk out, good info in-- good answers out.
and welcome to the forum.
Although it is uncommon for the G2 to have it's recoil spring immediately fail catastrophically, it is not an entirely unknown issue for having a problem arise. An end of the spring coil at times can pop over it's retention (end of guide rod). This can be simply remedied. However, if part of the guide rod snapped off, then you'll need to contact Taurus for a replacement to be sent to you.
Other than that, we do have a member here who is close to releasing an all steel guide rod assembly upgrade. You can read about that here in this thread: http://www.taurusarmed.net/forums/m.../146124-pt111-g2-steel-guide-rod-project.html
Sorry for your initial misfortune, but I encourage you not to give up on the G2 just yet. It is in fact a fine handgun.
The outer spring did pop over the end. It looked as it can be forced back but the retaining c-clamp is bent so it would happen again. I would not trust my skill in repairing it. I did just order a replacement for the recoil spring. I also have the 24/7 45cal. It is much lager but I could see how it is when right
