My understanding of the NAA minis is that the hammer mounted firing pin rest on a notch and not on the chamber allowing it to be carried with a full cylinder. I have a 22lr only mini and while looking at it unloaded it seems the notch is in between the chambers, but when I put the hammer down ad look down the barrel (unloaded) the chamber is lined up with the barrel. This leads me to believe that the firing pin is resting on the chamber. If I try to lower the hammer down on the notch the cylinder is not lock and if you wiggle it, it rotates to the chamber being lined up with the barrel again.

Is this normal. Would it work different if loaded (don't understand how). Is something wrong?
 
My naa mini allows me to see the notch from the top where there would normally be a sight. I slowly cock hammer backwards untill cylinder rotates freely lining the notch with the hammer I squeeze trigger gently while holding hammer letting it fall gently into notch. The hammer itself will keep the cylnder from rotating if it is in notch.
 
After I got my Black Widow I practiced putting the hammer in the safety notch with the gun empty and am now comfortable doing so. The is a little play because the notch is slightly wider than the hammer..
 
When I carry my NAA mini hammer down in safety notch, when I check it later it will always have slipped out of safety notch, which I now carry hammer down on empty chamber. Gonna have to call them to see what they have to say.
 
Got it figured out. It took some playing around to figure it out. Wasn't fully letting it down so it was not catching in the notch. As noted I had to keep the trigger depressed the whole time I was lowering it to get it to actually catch in the notch

Thanks for the help

That could be a holster problem, qwik. The hammer shouldn't be getting bumped enough to knock it out of the notch. A good holster will protect the hammer.

Make sure you pull the trigger to let the hammer fully rest in the notch. Otherwise, your hammer is in the half-cocked position and the cylinder is allowed to rotate. It's not really half but more like 1/10 cocked.

Like the other guys said, a NAA needs to be in its own pocket holster for some minimal protection. One of the weakest parts is the cylinder pin. It is very easy to bend. For example, have it in your back pocket w/o a pocket holster and sit down hard; the pin can get bent. Once bent, you will have timing & ignition problems.
 
It does seem like it just barely catches half notch, been using the standard mini holster. Holster does have heavy wear, Have a friend with one I'll compare with his. Thanks
 
Meaning catches the cylinder notch, when cking the cylinder rotation it is locked, but pulling back on hammer very lightly will release cylinder to rotate freely

Yep that was what I was doing when I started to thread. I wasn't holding the trigger. The hammer was staying in 1/10 cock. It is working fine now
 
The cylinders are the same length. NAA will install a free replacement cylinder with the safety notches if you pay return shipping. I just had it done on an older one that I purchased in a pawn shop with a sticky (badly gouged) chamber. It came back looking like a brand new gun.

My minirevolver doesn't have a safety cylinder? Can I have one installed?

Yes, we would be happy to install a replacement cylinder, free of charge. Return the gun to the factory and we will update it promptly. There is a return shipping fee - see our shipping instructions page for more information.

The safety notch operation is strange and should be practiced a few times with an empty gun until you have it down. It is very unusual, and hard to describe, but once you have it right, you'll know.

The cylinder should resist even a determined effort to turn it, and the hammer should be 100% forward. The holster or other carry device should protect the hammer AND trigger.
 
Someone have a close up pic of the newer cylinder with the notches? It's been some time since I have seen one.

You can see the notches fairly well in this pic from the http://northamericanarms.com website.

The safety notches are as deep (or a touch deeper) as the place on each chamber where the FP lands, and with the hammer fully forward into the notch, the cylinder should have very little play. You get used to glancing at the rear to see that the gun is halfway between chambers, or at least I did.

Now I want a .22short NAA mini purely for fun - the .22wmr/.22lr convertible is HUGE compared to the short-only guns.
 
That pic is why I said the cylinder was longer. In mine you see where it stops, and in that one there had to be more meat, longer, to cut notches in. Everything else about the cylinder is the same.
 
just compared mine to friends, his notches looks just like mine but his is locked tight in safety notch were mine with a little force will slip out and rotate. Guess have to give them a call and see whats up
