Have you read the manual? You PUSH out the take down, Slide Lock/Release, lever from the right side using a small pin of some type. IIRC they actually give you a tool to do that. At least they did in the one I bought, IIRC.I just bought the CSX E Series 3.6 and put 50 rounds through it at the range. I shot it better than my carry gun S&W EZ performance 9mm. When I get more rounds through it I will probably start carrying it instead. Better accuracy and more rounds. Seventeen rounds versus 7+1. The problem for me is being in my late 70s and having arthritis in my right hand, having lost some hand strength is the take down!!! I really struggled to get the take down pin out!!! I finally got a q-tip bent in two in the slide which got the take out pin lined up the TH in the wording WITH only then could I get the pin out. But the pressure to get it out is substantial hopefully it will loosen up with more range time!!?? I was very frustrated in the beginning. I took a photo for future reference!!! I probably won't clean this gun as often as I normally do. Just my initial post here.


I had the same problem with my CSX take down pin. Sent it back to S&W. No joy. Your solution with the Q tip is similar to what I use. And I have read the instructions more than once.I just bought the CSX E Series 3.6 and put 50 rounds through it at the range. I shot it better than my carry gun S&W EZ performance 9mm.

Mine has a sweet spot where the pin just pops out.I had the same problem with my CSX take down pin. Sent it back to S&W. No joy. Your solution with the Q tip is similar to what I use. And I have read the instructions more than once.
There's my problem right there, I've never won anything. I don't clean as often as I otherwise would but that is a poor solution.Mine has a sweet spot where the pin just pops out.
It feels like winning a carnival game.
After market M&P front sights (like M&P Shield) should work on the CSX.Are there aftermarket sights available for this gun? Does it share dovetail dimensions with any other Smiths?

At my age with a lack of hand strength and severe arthritis in my right hand I had to find something better than q-tips. I got my Weaver tool kit and started trying flat head bits. I eventually found one that when inserted into the loaded chamber indicator cutout was the exact spacing to get the take down pin out. Put that bit in and a couple taps on the punch with a hammer and out it goes! That's my solution.There's my problem right there, I've never won anything.

Just bought a 3.6" CSX-E to add to my EDC rotation. Love the ergonomics! I've configured mine with the large grip module that allows the 15rd mag to be used without the spacer. I'm looking forward to running it this weekend.
