Because of my inattention during a BS and Cleaning session, I accidentally jammed my KP90DC's slide so it wouldn't move in either direction.
I toyed with taking it to a gunsmith and I even spoke with Ruger support (which the guy I spoke to must of been having a bad day) but seeing that with shipping and repair costs exceeding $100, I decided to give fixing it myself a shot...
I'm happy to say, I was able to fix it and here is how I fixed it.
First, the slide got jammed when I put the slide back on with the ejector down. This prevented the slide to move back to cock the hammer. Well I totally freaked and tried moving the slide forward and it wouldn't move as well. I was at total meltdown now...
Fast forward to yesterday: I searched high and low on how to take apart a K90 and found some that made sense, but I've never took apart a gun at this level. Here's what I did to fix it sorted by issues.
1. Slide not moving towards the hammer: The Guide Rod had jumped out of it's slot at the barrel end so it couldn't extend from the hole as the slide moved backwards. I took a small screwdriver and prodded it to go back in place. Once this was done I was able to move the slide back.
2. Slide not moving off the front of the lower assembly.
a. I remove the grips
b. I pushed out the retaining pin for the "Hammer Spring Seat, with Lanyard loop" (V02400) and removed it and the "Hammer Spring" (V00400) and the "Hammer Strut" (V01601).
c. I pushed out the retaining pin for the "Ejector" (Q00900) releasing it and the "Ejector Spring" (KV00951). I had to pry around to get the Ejector removed because of its shape and how it bends around the frame.
d. I then removed the "Hammer Pivot Assembly" (KV22300)
Once these items were removed the slide slid off the front of the gun with no problem.
3. Now comes the tricky part, reassembly.
In this picture each of the components are numbered by the order they are reinstalled into the gun.
a. Insert 1,2,3 into the gun and press down the whole frame on the lanyard loop to compress the spring and slip in the retaining pin.
b. Press and hold down the lever "A", the "Ejector" has a tab that goes behind this component.
c. Place the spring "B" into the ejector "A" in the same orientation as in the picture. The top hoop of the sprint slips over that tab you see on the ejector just below the letter "A".
d. Now compress the spring and the ejector so that you can insert the retaining pin.
Here you see how the spring should be installed.
Here you see the top hoop of the spring wrapping around the ejector's tab.
e. Now take the "Hammer Pivot Assembly" and insert it into the gun making sure the hammer is pivoting around this component.
Install the slide as you normally do and the gun is back in working order.
