I have not had any problems.. But I have only used High Velocity ammo. The manual says you can use Standard Velocity but I have not tried any. That may be where some are experiencing problems.

As far as extra spring.. I have not seem any in just a regular field stripping. It does have a hollow hex or allen screw on the right side you need to remove before disassembly. Other than that it is like a 1911.
