Yes, I understand that they are too thick or too wide now. I'm just addressing OMFS' concern about grinding them too thin.They definitely do not wobble. The problem is they’re way too tight.

I probably should have just bought a Glock! I watched too many damn videos of people flying through the build with a drill, throwing it together and everything working fine. I figured if I took my time, checked and double checked everything, that I would be ok. For the life of me I can’t figure out what the hell i have done wrong. But I guess if the rails won’t fit in the slide then it’s the wrong rails or wrong slide. Hopefully I’ll get at least some kind of answer tomorrow.

These are the invoices for the parts I ordered. Everything should be compatible. Not sure why the slide slot is too narrow to go on the rails/locking block unless they sent the wrong one.

Ok, I did some “high tech” fanagaling and got the slide running on the rails smoothly. I put it back together 1 pin at a time and when I get down to the back pin on the locking block, it pulls the back down enough that they aren’t level anymore and I get the grinding again...
^You chose an ambitious starter project, which I respect, but it's far from the path of least resistance.
Looks like you at least ordered the correct parts (assuming that's what shipped).
^this appears to reinforce my earlier guess that your drilled holes (at least one) is slightly off - keep in mind we're talking thousandths of an inch, which is why they can easily look correct but still be off.
Other possibility is the block is out of spec, but the pic seems to show the rear locking block pin hole a hair lower than I would expect it to be. The front hole is machined at the factory, and is much more likely to be true than the self-drilled rear hole.
If the rear hole is just a tiny bit too low, then when the rear pin is inserted, it will pull the block down too far and shift the plane of the front rail - in this case, likely just enough to prevent the slide moving backwards. The grinding is likely from the front rails rubbing on the slide with increased friction as the slide is being pushed up by the rear of the frame due to the small angle shift in the plane of the front rail.
Possible way to check if rails or hole is out of spec would be: does front rail cam-down in the back when the trigger pin is inserted but without the rear locking block pin? Are the trigger amd rear locking block pins easy to insert, or does whichever is inserted second take a bit of force?
If the trigger pin does not force the rail down, but the rear locking block pin does and is difficult to insert after trigger pin, then your driled holes are likely off.
If either trigger or rear locking block pin forces the rear of the block down, and both go in with same resistance, then your block is likely out of spec and needs to be replaced...
Just my .02

Well, that's true. The rear rails have to be level, too.Problem is, I’m trying not to bend them completely out of shape which is the point if no return. The slide won’t even start to go over the front locking block to even test if the rear rails are high or low now.
The key is to just keep at it and stay patient (easy to remove material, not so much for putting it back...)Getting frustrated! It will fire 5-6 rounds no problem, then have a failure to feed. Clear that, then after 5-6 more another failure to feed. Gonna do some more polishing and try again Monday.

Just wanted to say stick with it and don't give up...I’m out of ideas! Emailed Polymer80 and sent some pics. We will see what they have to say. For some reason when I insert the front rail module into the frame, even just start it in, the slide starts to get hung up. Only thing I can think of is, they’re so tight in the frame that it’s bowing them out. But I don’t want to take a bunch of material out of the slot where they are supposed to go, because they have to be a little snug or else I’m gonna have another issue. I have assembled, dis-assembled, sanded, polished, measured, checked hole alignment in jig, and anything else I can think of, if P80 can’t help me, I’m not sure what to do next.
Edit: Just checked my email and Polymer 80 is sending another front locking block. Hopefully that’s the problem.
