Title: Help! The hardest of all - the 75 slide release retaining pin
Post by: briang2ad on May 11, 2019, 02:30:13 PM
Easy to take OUT, but hard to get back in - any hints?  I am trying to push the spring down into position, then driving the pin in with a THICK punch with the frame covered in tape, but no luck.  Even a slight chamfer to the pin on the end I am driving in is not helping.

I swear I did this with a preB before, but this is a mess and I don't want to ruin my newly Nitrided frame.

right side of the frame, spring has to be pushed down to get the pin in above it?

Isn't that pin already chamfered on the inside end?

I thought they usually just pushed in once you got the spring end down far enough below them to allow the pin to slide in.  Then the spring pushes up into that groove that runs around the pin and holds the pin it place?

Are you afraid of scratching the frame on the inside?

Do you have a brass punch that you could use to push the spring down?  Or a popsicle stick cut off square on one end?  Or, that small common screw driver blade with the notch cut (dremeled?) into the blade to help with the Omega decocker spring installation trick that someone here came up with?

Good luck with it.  We'll need pictures, of course.  I'm getting serious about getting my little CZ85 Compact clone done.  That kydex holster is working on the muzzle end of the slide, the slide release levers, etc.  So, along with the pictures we'll want some details on what you had to remove, take off, etc. to ship it off for the work.

Make sure the spring is pressed down and allow the pin to go through.  Try with a slave pin or a small punch to see you have the clearance to proceed.  I think that you did not press the spring deep down enough.

Thanks gents.  Needed to get all aligned right and press the spring down enough and it goes in.  Not easy peasy.
