redwoods Posted November 26, 2011 Share Posted November 26, 2011 I have a Dan Wesson PM9 1911 in 9mm. I did some mods by putting on a dawson ice magwell, and thats it. When I rack the slide and pull it to the rear, then release it, it hangs up for a second on the disconnector. The bottom of the slide at the breach hits the top of the disconnector. If I pull the slide back, then slowly release it, it will stop the slide for a bit but it may also drop the slide. How do I fix this? Thanks, Randy Link to comment Share on other sites More sharing options...
fastluck13 Posted November 27, 2011 Share Posted November 27, 2011 it will stop the slide for a bit but it may also drop the slide. How do I fix this? Stop it as in it will stay that way or stop it as in you can feel the bump as it depresses the disco? Link to comment Share on other sites More sharing options...
10ring Posted November 27, 2011 Share Posted November 27, 2011 Did you replace the Mainspring Housing too? Link to comment Share on other sites More sharing options...
Jim Watson Posted November 27, 2011 Share Posted November 27, 2011 Check the sear spring center leaf's tip and the bevel on the disconnector where it bears. My SA that acted that way had a sharp and rough tip on the sear spring that was just propping up the disconnector. A new Colt sear spring with smooth tip and the gouges polished out of the bevel on the bottom of the disconnector fixed it right up. Link to comment Share on other sites More sharing options...
stardust tommy Posted November 27, 2011 Share Posted November 27, 2011 read this http://www.brownells.com/.aspx/lid=12535/GunTechdetail/2-lb-Trigger-Pull and see how much spring tension you need , where to polish the disco, polish the center leaf spring etc chamfer the sides of the top of the disco to prevent drag in the disconnector slot, chamfer the underside of the breach face or a look @ this http://forums.1911forum.com/showthread.php?t=283863 gr T sorry for my "poor" English Link to comment Share on other sites More sharing options...
Jim Norman Posted November 27, 2011 Share Posted November 27, 2011 Take a look at the slide, the bottom corner on mine was so sharply square that it would catch where it ran over the disconnector. I took a small narrow stone and just polished this edge off just the slightest bit. No problems with that for about 100k. It doesn't affect the trigger pull or any other part of the firing mech.

Roadrider18 Posted November 27, 2011 Share Posted November 27, 2011 You had no issues prior to installing the ICE magwell? You are positive the disconnector currently stops slide movement? Disassemble the receiver and reinstall all parts (including springs) paying particular attention to proper installation. I do not recommend filing on the disconnector until you are absolutely positive the disconnector is the issue. A too short disconnector can have a very undesirable effect.

redwoods Posted November 29, 2011 Author Share Posted November 29, 2011 The dawson ice magwell is a magwell and mainspring housing combined. I looked at it agian and the disconnector definately sticks up as high, or higher than my other 1911s. When I pull the slide back, then let it back forward, it goes smooth then slows when it hits the disconnector, then closes. I will take off the dawson mainspring housing/magwell and return it to stock. Then see what it does. I pushed down on the disconnector using a punch when I had the slide to the rear and it is stiffer than my other 1911's. Randy Link to comment Share on other sites More sharing options...
Roadrider18 Posted November 30, 2011 Share Posted November 30, 2011 Randy.... If you have a micrometer, measure the overall length of the disconnector. Do not take a file to the disconnector just yet. If the disconnector is to spec, there is a specific tool to smooth out and enlarge the disconnector pocket in the slide. Once again, I would not alter any part until you know exactly where your pistol (and parts) is (are) relative to specifications. Link to comment Share on other sites More sharing options...
xcelr8n Posted December 6, 2011 Share Posted December 6, 2011 Could it be that you just need a stronger recoil spring? Link to comment Share on other sites More sharing options...
MILDOTS Posted December 6, 2011 Share Posted December 6, 2011 I had the same problem with my 9mm edge. It smoothed out after 1000 rounds or so. My 4 lb trigger pull went down to 3 lbs also. Link to comment Share on other sites More sharing options...
TicoCafe Posted January 13, 2013 Share Posted January 13, 2013 Randy I just purchased a PM9 over the weekend and I am having the same issues with the slide getting hung up by the disconnector. A firm push forward will close the slide... How did you end up fixing the issue? I have not taken the gun out to the range as im nervouse this Issue will create other issues. I emailed Dan Wesson on the issue now all I can do is wait. Link to comment Share on other sites More sharing options...
Extremo Posted January 13, 2013 Share Posted January 13, 2013 If the slide hangs without pressing the trigger, check sear spring tension and that it's seated correctly. Sometimes the MSH and spring doesn't fit together without adjustment. If the slide hangs when You press the trigger then check that the disco clears the hammer strut.

TicoCafe Posted January 13, 2013 Share Posted January 13, 2013 (edited) This photo show where the slide binds when you rack the slide back and forth (no magazine)... It appears the disconnector does not actuate as smoothly as it should. Edited January 13, 2013 by TicoCafe Link to comment Share on other sites More sharing options...
paul gilman Posted January 13, 2013 Share Posted January 13, 2013 there is a spec for disconector length, check that with mic, then check the ramp on the disconetor that the 3 prong spring rides on this should be polished with out removing much metal also polish the center leaf on the spring where it contacts the disconector. Then with the slide off function the trigger and watch the tip of the disconecter and see how much it moves back and forth then push it down and see how smooth it operates. Then check the forward edge of the slide lightly break the edge and then. Link to comment Share on other sites More sharing options...
392heminut Posted January 13, 2013 Share Posted January 13, 2013 Then check the forward edge of the slide lightly break the edge and then. This is what I was going to suggest. If there isn't a slight bevel on the bottom of the slide where it is hanging up on the disconnecter you need to bevel it a small amount. It doesn't take much.

I checked the bottom of the slide where it hangs up last night...Suprisingly there is No Bevel built into the slide at all...its cut at a perfect 90 Degree Angle. I will wait to hear back from Dan Wesson and proceed from there. Link to comment Share on other sites More sharing options...
