Got a .22 conversion for my Colt series 70 1911

[Sgt Hochbauer]

As the title says I received a .22 conversion with the 1911. The gun shoots perfectly with the .45 slide. But with the conversion it does not go into slide lock. I have tried 4 different types of ammo. Any ideas or suggestions would be appreciated. It is a Colt conversion slide and barrel.

Doesn't go to slide lock when last round is fired? 

Typically, ammo is too weak or something in the conversion kit is too tight a fit or too heavy a spring, to let the slide be pushed back far enough to trip the slide lock.  What brands of ammo have you tried? 

.22 conversion kits have a long history of being very finicky.   A good target pistol gunsmith would be the best solution I can recommend.

good luck, GJ

Thanks for your reply. I have tried Aquilar,Winchester and CCI 2 different types. Unfortunately the party that left it to me is not around to ask if he had the same issue.

 

 

Thanks

Will it go to slide lock if you manually operate the slide to empty the magazine?  Your conversion may not  provide that feature.

check the magazine/magazines against a .45 mag.

Make sure the "slide lock" cutout in the .22 mag is the same as the .45 mag. Sounds like the slide lock button is not going through the cut out.

Not all of the conversions have a working slide lock. Not sure if yours does. If not, it’s operating as designed.

I am thinking a call to Colt will take place and see if they can provide a solution.

Thanks again for you info.
