Ruger MK1 barrel replacement

Can anyone tell me how to remove the barrel from the receiver on the Ruger MK1 pistol ? It seems to be pressed in place, and I can see no retaining pins. This makes me assume that the barrel is pressed against a shoulder in the receiver and therefore must be pressed into the receiver to remove it.

Thanks for your help.
 
I have no idea why you want to replace the barrel, but I would send it back to Ruger. It is easy to mess up with those guns, because of the way they are made.

You can have a smith put it in a barrel vise and unscrew the barrel, but it is easy to crush the receiver and ruin the pistol. Best bet- send it to Ruger for a new barrel. Call ahead and tell them what you are looking for, you will get good service and good quality parts from the factory.
 
Those barrels are not installed in the way most folks think. They thread a piece of thick wall tubular steel at one end. Then they screw in the finished barrel and really tighten it. Then, using the feed ramp as a reference point, they cut the ejection port and do all the other work on the receiver.

Just machining the ejection port causes a "merging" of the parts, making the barrel very hard to remove.

FWIW mine came off quite easily. I did the whole deal with cerro-safe barrel-wrench jaws, etc, primed my self to really lean into it...and, it just unscrewed. Pretty anti-climactic, really.
 
Thanks guys for your responses. The reason I want to remove the barrel is to replace it with a bull barrel and then install adjustable sights on it.
