I realize that there are different sizes of barrel links for a 1911.  But I am having a problem of finding the size in a barrel link pin for a new Colt Defender barrel -- most are too small in size for the barrel.  I do not want to stake the pin because I may want to try different barrel link sizes.  Can anyone recommend a course of action -- do you an GI barrel link pin would work ?  Thank you.

I took a measurement on the barrel link in my Defender, the total length is 0.6180

I have a package of Kings National Match barrel links for govt. and Commander those links also measure 0.6180

They would appear to be interchangeable, however it's late and the one in my Defender is either very tight or staked, and I'm not going to drive it out to insure they are identical.

Why are you interested in going with a different length barrel link?

Thank you for the measurement but I my problem is finding a barrel link pin for this Colt Defender barrel.  I may have to order one from Numrich Corporation because Colt made a thicker model than the Standard sized barrel link pin.  Thank you, again.

Never mind, my friends. While the barrel link pin was under pressure from being assembled.  It no longer is falling loose or out of the barrel, thank the gods of the 1911.
