Better accuracy with the NAA Mini revolvers

I have seen some youtube videos of people shooting the North American Arms Mini Revolvers and getting pretty good accuracy by cutting down the front sight.

The tall front sight on these guns is just for looks. Some of the owners have filed the sight all the way down and polished the top of the barrel and others cut it down to the same height as the back sight.

Both of the videos I watched were very impressive. Has anyone done this?

Well its not an NAA, but a forerunner in the form of a Freedom Arms mini in .22LR.

Like MANY FA mini-revolvers, the "glued on" front sight had fallen off, so I guess this qualifies it.

On or off, the upward muzzle-whip effect of these little-buggers with their thumb-sized hummingbirds-head grip means that accuracy with or without front sights is relative to your luck and proximity to the target.

Still, cheap and a hoot to shoot.

Modifying the sight won't affect the inherent accuracy of the revolver, just how it is aimed. The little derringers don't have much sight radius and need all the help they can get. Cutting down the front post just raises the point of impact and if the revolver shot low that mod would be an improvement. I've shot NAA's 4" Mini Master quite a bit and the thing is capable of a 4" group at 25 yards offhand! Their shorter revolvers won't come close to that. The challenge that cannot be overcome with the things is the stiff trigger pull, and tiny contact point on the finger which creates pain before you finish a box of 50. Also, NAA's quality control is a bit lacking. I've seen some very roughly finished bores with junk rifling and burred muzzle crowning. The cylinders on the NAA's I've shot have locked up tight, though, and the exteriors were nicely finished.

I'm thinking you've seen some used guns, maybe that the bores weren't really clean? Or abused? I've never seen a bad bore, or more than a tiny tool mark on any new NAA. They have a reputation for great fit and finish. My NAA Guardian 32 was mark-free out of the box.

The front, and rear, sights on NAA revolvers are intended to work as well as they can for their size. Some owners monkey with them trying to get accuracy at a longer distance that's not practical. These are intended to be "get off me" guns, shot no farther than 10-20 feet, not target pistols.

There have been some issues with the sights on their newer breaktop revolver, the Ranger II, but I think those have been cured.

I'm on the NAA forum, and you can find lots of solid info and opinions there. I just have the Guardian semi-auto, no revolvers, but I still find them interesting.

I cut down the sight on mine to get a more accurate picture. I think it is more important to get a bigger grip to get a better purchase on the gun. They are not a target gun,but you can hit your target with some practice and are a hoot to shoot. Jim

Better grips and a better trigger greatly improve the person behind the gun accuracy. I have gotten my trigger pull down to 5.5# with almost no creep. The trigger return spring is very stiff and mine read over 3#s. I filed it down from the inside until it was down to just over a pound. I then lightly polished the hammer notch and shortened the engagement surface. I personally wouldn't take it down to breaks like glass stage do to the size of the gun. I also replaced the grips with the old style rubber grips and reshaped them so that my middle finger doesn't interfere with my trigger finger.

Mine is a Mini Master so the sight radius helps a lot but I can bust clays at 25 yards now where before it was a random event.

Forgot to mention a few things I learned the hard way if you go inside your gun.

The main spring can't be lightened, it needs all it has to prevent FTF's.
The screw is reverse thread, righty loosey.
Save some frustration and glue the straight leg of hand spring to the hammer.
The main spring is the last part to go in after the side plate is secured.
Everything inside is tiny and hard to find if dropped!!!

I have a Black Widow in LR and it's great to shoot.
The first 10 rounds out of it were inside 2" @ 7 yds.
And that's with fixed sights.

The Mini on the other hand is quite a bit more challenging.
I need to spend a lot more time with it to figure out where it's hitting.
And yes, there isn't a lot to hang on to.

Take a few of the big rubber bands they use on the celery at the grocery store, and wrap the mini's grip with them. It works like the rubber jar top grippers and gives a much greater grip in both bulk and tackiness. A few large rubber bands change everything. It's an old cops trick from way back on undercover guns and backup guns.

I don't use my NAA in .22WMR a range gun or plinker necessarily. I carry it at times when I have to wear a suit or somesuch for a function. I have the folding pocket clip grip on it. The folding clip grip is larger than the tiny stock grip and really gives me a better purchased on the gun. Its very light and concealable. Also, while not a one-shot stopper, the .22WMR packs a bit more punch. I figure that at close self-defense range it is accurate enough as is and I just want to stop the attack and beat a fast retreat.

Don't forget, they fit sloppy and you'll need to bed them w/ some epoxy to get a decent fit to the frame. Don't forget the mold release! [Wax, Pam, whatevs... just something to keep the epoxy from sticking to the gun while it sets up & adheres to the grips...] And they're still not as good for accuracy as the Secret Service grip that NAA sells, but do remain more concealable like the original bird's head grips.

I tried the revisioncv grips and didn't like them that much. They are still to narrow to be comfortable. I did a little better with the boot grips from North American Arms. But for my hands, the Mini-Master grips are the best feeling:

They do increase the overall size of the NAA reducing one of the revolvers bests features; it's size. But if you want some nice looking, real wood, "potato" grips, check out:
