Hammerli AP20 Air Pistol

Monday, December 2, 2013

Some years ago the idea crept into my fevered brain that I was a really talented rifle shooter, and I set out to prove it by getting involved in some 10-meter air rifle competition. Both 10-meter air rifle is an Olympic sport.

I found out a couple of things: (1) I am not a really talented rifle shooter and (2) the folks who are shooting high scores in ten meter air rifle wear special shoes, pants, jackets, gloves and even special underwear (no kidding!). I was shooting scores that were so low that it seemed doubtful whether spending hundreds of dollars on all the associated shooting apparel would be a worthwhile investment, so I didn’t bother.

At the same I wondered if there was any Olympic shooting sport that one could get involved in without having to drag around a whole lot of ancillary gear. And there is – 10 meter air pistol. With air pistol all you need is an accurate air pistol, some pellets, and the ability to align the sights, squeeze the trigger, and put some pellets in the 10 ring.

If you want to get started with 10-meter air pistol, the cheapest possible route that I know of is to start with the Daisy Triumph 747 pistol. It’s single-stroke pneumatic pistol that delivers a boatload of accuracy for under two hundred bucks. What you don’t get with the Triumph is a lot of adjustability to meet the needs of your shooting style. In fact, if memory serves, the only thing that is adjustable on the Daisy Triumph is the trigger. For 10-meter air pistol competition, the minimum trigger weight is 500 grams (17.6 oz.).

At the other end of the 10-meter pistol spectrum, you can easily spend two thousand dollars or more for a full-race 10-meter competition air pistol such as a Feinwerkbau. These pistols offer lots of adjustments to meet the ergonomic needs of the shooters.

The Hammerli AP20 falls pretty much in the middle. For under a thousand dollars, it delivers superb accuracy, a crisp trigger, and a number of adjustments to meet the shooter’s needs or preferences.

Before we get to what those adjustments are, let’s take a quick tour of the AP20. The main pistol grip is made of molded polymer that is stippled for improved grip. Attached to the grip are a hand rest and a palm rest. Forward of that is a curved, flat-blade metal trigger.

Above the trigger is the main receiver, which is finished is a matte silver finish and to which the cocking lever is attached. Attached to the front end of the receiver is the pressure reducer. As it comes from the factory, the pressure reducer is configured so that the air reservoir (also finished in matte silver) hangs down in front of the trigger assembly.

Forward of that is the barrel, which has a lightweight plastic shroud and a ported aluminum compensator at the end that serves as a mount for the front sight. Moving back along the barrel, on top of the receiver is the breech and behind that a microadjustable notch-type rear sight. That’s all there is to the AP20, and the fit and finish are entirely appropriate for a competition air pistol.

Now, let’s take a look at the adjustments that the AP20 offers. Both the palm rest and the hand rest can be adjusted for position to suit the shooter’s hand, and they can be swapped around to configure the pistol for left-hand shooters. The cocking lever can be changed from right- to left-hand configuration. The front sight can be adjusted to one of three different widths, and the rear sight can be adjusted for elevation, windage, and the width of the rear sight opening.

The trigger can be adjusted for weight, travel and stop, and perhaps most surprisingly, the pressure reducer can be configured so that the compressed air reservoir lies parallel to the barrel.

The last adjustment is purely decorative. When I first opened the plastic case for the AP20, I was confronted by five plastic tubes: blue, gray, fluorescent orange, fluorescent pink, and fluorescent green. Frankly, I didn’t know what to make of them. I thought maybe they were 10-meter competition drinking straws. They are, in fact, replacement barrel sleeves. The AP20 comes equipped with a black plastic barrel sleeve, but if you want to distinguish your pistol from others at the range, or if you simply want a different look, it’s easy to change from one barrel sleeve to another.

In the end, the AP20 delivers a lot for a reasonable price in the rarified air of competition air pistols. It launches light hobby pellets at around 510 fps, will put pellet after pellet through nearly the same hole at 10 meters (with the right pellet), delivers around 120 shots per fill, and will put a huge smile on the face of any wannabe 10-meter air pistol shooter.

Now, listen Santa: I’ve been really, really good this year . . .

Til next time, aim true and shoot straight.

    I am a french shooter (Club de tir La Poudrière de la Fère)and I have the project to buy an Hammerli AP 20.Are you satisfied with this gun ? Isn’t it too light a gun ? Is the bootle without manometer a good idea and is it sufficient ?
    Thank you,

    Daniel Lambert

      I no longer have the Hammerli in my possession. I believe the review speaks for itself. I didn’t find the gun too light, and I think 120 shots per fill is plenty.

    Does this have the extreme international angle grip? I have a fused wrist and cannot use the extreme angle. I was able to get a 1911 angle grip for a Pardini HP .32 and it is very comfortable. Noticed they have accessory grips that you can buy. Are they all international angle?
