I just purchased a stripped TSD slide milled for RMR.
Having never installed a firing pin channel liner before, I watched a few videos and then used a large diameter puch to push it into the slide. About 3/4 of the way I encountered some resistance and use a small mallet to lightly hammer it in the last few inches.
When the time came to put in the firing pin assembly, I have to push it in the last 1/8" of an inch, and it doesn't "float" freely as it should.
I examined the liner, and it looks OK, but I wonder if it's kinked or damaged? There is also appears to be some plastic marks in the channel where firing pin head is supposed to be.
Since I don't have any spare liners, I am wondering if there is a way to trouble shoot the issue "non destructively" towards the liner.
Questions:
1. Is it possible that the stripped slide is somehow out of tolerance?
2. How could "light hammering" damaged the liner?
3. Is there a way to verify the liner is in correctly?
Thanks!
