Just purchased a 908 and I need to move the front sight to correct the poi.
Since these are plastic sights what is the proper way to move the sight,is a sight pusher needed or can you tap it with a pin punch?
I've done both and take my word for it, a pusher is preferable. Use a plastic or hardwood drift if you have to bang on it. Both sights on my 908 are really tight.
Don't forget to put a pencil mark on the sight and gun so you can tell how much you've moved it.
They are pretty soft plastic and they are tightly fitted to the slide. I bought a used 908s and the sights were a bit banged up like the gun had been dropped, so I installed some new sights and had the best results using a wooden dowel for a punch.
I used a wood dowel.... I shaped the end of the dowel in a slight dovetail with a sharp blade. Added a slight edge to catch the rise angle mid range of the sight. Oil it well before hand with CLP or penetrant. Drift it slowly with a light hammer drive.
One other thing. There are two springs under the rear sight that operate the tension to the ejector depressor and the the firing pin safety plunger. As I recall, one flew when I did mine as I was not paying attention to the springs. As you're drifting it out. You will see the first and then the second. IIRC the second flew and luckily I recovered it.
