Aluminum Slide?

The reason the Kimber won't lock open, is because they made a special mag that does not have the tab that activates the slide lock. If you simply insert an Advantage Arms mag, the slide locks open. The AA kit has put a very small steel insert parallel to the slide lock opening.

So, let me ask a couple of stupid questions.

1. Why not use Advantage Arms mags in the Kimber?
2. Why is last shot lock back so important in a .22?

It's more important on a rimfire than a centerfire. You can normally dry fire a centerfire with no damage but you can ruin a rimfire doing the same thing.
 
Ok, I understand the answer on the rimfires. But, now, why not use the AA mags? Easy solution unless there's a problem with them.
 
There is no problem using the AA mags in the Kimber kit. None at all, however, how the thread started, was that I was concerned that the Kimber slide will quickly gall, when using the AA mags being Kimber added no steel plate or pin in the slide stop notch.

I intend to add a tiny piece of hardened steel or simply drill and install a hardened dowel ( approx 1/32 or up to .040) being I measured the slide, and it is .142 wide at the area of the slide stop.

This will give me best of both worlds. The ability to use the Kimber conversion kit, which I like a little better, and using AA mags, I get last round held open.

Thanks for all the replies

I believe most modern 22s can handle some dry fire, either because the barrel steel is harder than what was used in older firearms, and/or having a firing pin stop that prevents it from traveling far enough to hit the barrel.


If the OP can add the pin to the slide, it should help the side stop last much longer.
