First of all, you say the gun you have is Commander-length but then you say it has a 3.5" barrel? Which is it?
If by 'telescoping' you are referring to the guide rod, you likely have an STI recoil master. Here's a really neat webpage, showing what it is and how it works (along with a few other things). Use the buttons to make the slide and frame transparent:

Is this what you have? If so, you need a special plastic little tool. STI sells them.
Too many people miss the silver lining because they're expecting gold.
