This is a problem solving guide for the Ruger Mark series pistols. Rugers directions that come with the Mark series pistols are not only confusing but are not detailed enough to properly assemble/disassemble the pistol, leaving many with a paperweight. I ask that you request my permission (zxracer3) if this will be republished elsewhere.

Ruger Mark Series Assembly/Disassembly Problem Guide (*Key at bottom)

The mainspring housing won’t come out:
-To remove the mainspring housing first insert mag (mark III only) and then pull the trigger. Use a bent paper clip to flip the mainspring housing out of the lower. Next pull on the mainspring housing to remove it as far as you can. Once the mainspring housing has been started use a wooden dowel (golf tee) & mallet to hit the remaining bolt stop pin of the mainspring housing through the gun. NOTE: you must hold the lower part of the mainspring housing outward & away from the lower part of the frame while you are hitting the mainspring housing downward, otherwise you risk damage to the lower. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

The mainspring Housing won’t go back in <o:p></o:p>
<o:p></o:p>
Step 1: Make sure the barrel & receiver are aligned by looking to see if there is a perfect circle where the bolt stop pin enters. If not place muzzle end on table or something, and push down on the grip if extra force is needed. <o:p></o:p>
<o:p></o:p>

Step2: Make sure the hammer has fallen forward (vertical position) by looking through the mainspring housing channel. If it has not fallen forward insert mag (mark III only) and then pull the trigger, while placing something into the receiver (your finger probably won’t fit) to manually push the hammer forward (vertical position). Then be sure the hammer strut is RESTING against the lower, so that it is not in the way when you insert the mainspring housing. <o:p></o:p>
<o:p></o:p>

Step3: The bolt stop pin will often get stuck on the recoil spring, so go from the top of the hole where the mainspring housing pin is coming through & move the recoil spring out of the way with something. Then using the rubber mallet hit the mainspring the remaining way. NOTE: you must hold the lower part of the mainspring housing outward & away from the lower part of the frame while you are hitting the mainspring housing downward, otherwise you risk damage to the lower.<o:p></o:p>

Step4: go to 3 in key <o:p></o:p>
<o:p></o:p>

Gun is all back together & won’t fire. <o:p></o:p>
<o:p></o:p>
-You did not do the steps in key 3 correctly. You need to insert mag and hold the trigger while flipping up the latch from the mainspring housing. Then redo 3 from Key. <o:p></o:p>
<o:p></o:p>

Upper Won’t come off:<o:p></o:p>
-Go to 1 in Key <o:p></o:p>
<o:p></o:p>

The bolt won’t go into the receiver:<o:p></o:p>
-Go to 1 & 2 in Key <o:p></o:p>
<o:p></o:p>

The bolt won’t come out of the receiver:<o:p></o:p>
-Go to 1 & 2 in Key
<o:p></o:p>
<o:p></o:p>
*Key: <o:p></o:p>
1) The hammer is has not fully dropped into the lower. Visually inspect looking through the end of the receiver. If the hammer has not dropped, insert mag (mark III only) and then pull the trigger, while placing something (you finger) into the receiver to manually push down the hammer into its horizontal position. Then LIGHTLY tap with a rubber mallet to remove being careful not to hit the rear sites.
<o:p></o:p>
2) Be sure the bolt release is pushed down so that it is not protruding into the receiver.
<o:p></o:p>
3) Close the mainspring housing into the receiver: STOP! Before you close the latch on the main spring housing make sure there is some resistance on the mainspring housing causing it to protrude & not fully enter the lower channel. If there is not, the hammer strut has not correctly found its way into the mainspring housing. Continue to open & close the mainspring housing until you feel resistance. At the point of resistance close the remaining latch & you’re done.<o:p></o:p>
