After seeing haljeezy's and gcw360's modifications to their MKIV's I decided to combine the 2 and do the full Springfield Armory 1911 MC Operator. The only thing I haven't done yet is take it apart to remove and polish the trigger.
Function was the most important thing.
So when I received the parts needed to do this modification from the pro shop today, I was excited and I began the task.
I came across a serious issue though. I was sad to see that the recoil spring that was in my MKIV did not fit into the recoil spring cap that is used on the MKI and MKII.
Now before anyone says anything. The recoil spring is the same part number for every PTP. You can see this in the diagrams that are posted on the pro shop. It is part# 70.
So back to the dilemma... Why doesn't it fit? It doesn't make any sense. I see plenty of take down videos and you can plainly see how the recoil spring cap just slides on and off the spring easily...
My spring though will not go in at all. I'd have to twist it and jam it in there... Neither will the spring for my MKIII. its' just to large of an outer diameter.
This causes the slide to continue to cycle even after the last BB is fired. The slide will not lock back. because the spring guide and recoil spring get jammed up and will not move freely into the recoil cap.
So why is this? Are the newer springs thinner in that regard? I just don't get it. If I had known this was going to be an issue.. Well I would have ordered a spring too.. and asked they check that it slides into the guide easily.
This mod should have come off without a hitch at all. Obviously I need to call the pro shop on Monday because this makes no sense at all to me that the same part number shown... will not fit into the recoil spring cap that the pro shop sent me.
Thanks for reading... If anyone has some other solution, I would be glad to check into it. I don't want to spend any more on this though as it is complete... Well almost. I don't want to bore out the recoil spring cap either.
Have a look though.
