I just spoke with Tippmann Sports and they’ve pushed the release date of the TPX Pistol back a few weeks. We now expect to have them in and shipping around the 29th of May, 2009. Don’t be bummed though. Remember this is a quality Tippmann product and they don’t want to release something that isn’t up to their standards.
My understanding is that the design is great and prototypes work great. It looks like a couple of the parts from 3rd party were not manufacturered to Tippmann’s exact specifications. This caused issues with performance and so halted productions. Once these component issues are resolved then production should be in full swing.
