Fusion MSH wows .

Hey guys....Remember a few weeks ago I raved about the Fusion MSH ?....Well now I have a problem , just got back from the range put about 60 rounds through my Ultra Crimson great shot like a dream got home so I thought Id clean it , took the slide stop out but I couldnt get the slide of I thought WTF anyway after alot of lets say persuasion I got it of cleaned and lubed the gun , to my frustration ( to put it mildly ) I couldnt get the slide back onto the frame so after throwing the gun against the wall a few times lol not really , I saw what the problem was the grip safety wasnt releasing the pin enough for the slide to clear it in other words the slide was hitting the grip safety pin. I released the MSH enough to where the grip safety pin was flush with the frame and the slide went straight on . I know the MSH is sitting right with the hammer strut so it has to be something to do with the fusion MSH Id hate to swap it back to the Kimber original MSH , I was thinking of asking the gun smith at the range if may be he could shave a bit of off the grip safety pin it only need a fraction taking off ....What do you guys think?? Has anybody come across the same problem ?? any thoughts would be appreciated .

Thanks ....

I'd have the smith look at the main spring housing. They are not all drop in pieces.

I've heard of several MSH swaps and have never heard anyone say the fit was a problem. I agree that a gun smith can probably fix you up with a little nip tuck.

I suspect no problems will be found. User error the pin stopping slide removal is actually the fps plunger and is activated by the grip safety. Read the manual again. Series II Kimbers cannot be field stripped upside down or when the grip safety is depressed. Rolling this plunger over or shearing it off or shortie ing it by forcing the slide on or off can cause the gun to fail to fire. The hammer will fall but the fps stop will do its job and prevent the firing pin from going forward. Please report back if I am wrong I read this quick.

Wink Let Smitty look!!

Is it the original pin or did a new one come with the MSH? If it is a new pin, try swapping for the original. If that is not the case, let the 'smith take a look at it. That's why he makes the big bucks!!

The pin that holds the plunger, detent and mainspring in the housing have joint to do with binding the slide on the frame. That fps plunger is retained by the sear pin. There is no grip safety pin. The grip safety is retained in the frame by the thumb safety shaft.

Sup guys...I got my gun back from the gun smith today , apart from the sear spring being out of wack the screw that holds the mag well to the MSH was putting to much tension on the MSH spring , in other words the screw was to long so he shortened it a little , a lot of trouble for something so stupid..........Im happy again

I don't get that at all but have not seen the Fusion part. On all others the mainspring detent engages the groove of the mainspring housing pin. The pressure of the mainspring against the detent into this groove is what keeps the frames crosspin from walking out. Even if the screw was long it would have to hit the pin before the detent. I have not seen a two piece msh mag well that has the threaded hole all the way into the spring channel. I would love to see it but...

I am glad whatever the fix that things are good now.

Glad your happy. But, I have to agree with Mike, (I often do). If we are talking about the screw that holds the main spring housing to the mag well, the one that came with your Fusion kit, I can't comprehend why or even how it could be too long. I can see how too much torque applied to it might push in on the top of the MSP, but too long is hard to appreciate. And the mag well wouldn't seat right.
If you get a chance to ask the smith, could you have him explain what was actually happening to cause the problem? I'd just like to know for future reference.
