Parts for govt 1911 and ruger SR 1911

Will the parts for a govt. 1911 and a Ruger 1911 interchange? Charlie

They're the same gun. There shouldn't even be fitting problems, it should be straight across. You shouldn't have to change anything though. The Ruger's just new.

I have a 1911 that sometimes will not hold the slide open after the last round... Put the same mags in a friends 1911 and they all worked no problem....I have a Ruger coming so I want to swap some parts looking for a solution....Thanks Charlie

Your inner nub on your slide stop is worn or the dimple the spring *** engauges is too deep. And , contrary to myth , they must be fitted. Last one I had replaced by a gunsmith took at least three , and I'm sure it was four or five , times to get right.

I've had cases of mags that worked perfectly in my gun go to a friend's gun and they wouldn't go in easily or wouldn't lock the slide back. It's usually a small thing involved though.
