Now, just for kicks and grins, tear everything apart and do it again! If you installed the hammer block in backwards, the magazine will not insert and the gun won't fire. Disassemble it all the way back to the hammer block assembly, but you needn't take out the magazine catch.
If you didn't make it this far and end up having to send it back to Kel-Tec for assembly, I'm sorry. I've tried to document what I have done as well as I could. I know I need a better camera for these close shots, and I'm working on that. My camera doesn't have a macro lens and I apologize for that.
In the meantime, maybe Jack Fuselier's instructions for reassembling the grip might help! This was recently recently posted to the KTOG mailing list. Click below to read Jack's instructions.
Or, you can drop it by my house and I'll reassemble it for ten bucks. That sounds fair, don't it? That's a genuine offer. I'll remove the old grip and install the new one for ten bucks, unless I get too many people to take me up on it and I get sick of it!
Good luck, and let me know how it goes!
