Things I liked: Light and handles easily. You can add weights for stability if you like but they haven't made much difference for me personally. A great price for a great gun.

Things I would have changed: A second air cylinder would be nice.

What others should know: Shoots well. Unless you're planning to go to the Olympics (are you consistently shooting over 570?) this is really all the gun anybody is going to need. It's plenty accurate - way more accurate than 99% of gun owners out there. Between 200 and 100 bar you can get about 125 shots. I haven't had any problem with leakage when I've stored the gun with the air cylinder attached.

Things I liked: Great price.

Things I would have changed: Our school have 3 AP20's and 2 AP20Pro's. We have experienced a number of issues with these pistols. Firstly the cocking handles loosen with use and we had two break off. Parts were ordered at a hefty price and took months to arrive. One of our Pro pistols had the trigger assembly slide out. It is a pressure fit, not screwed so re-fitting was problematic. On balance these are not robust enough. We are now only buying Steyr pistols.

What others should know: We use Krale in Holland as UK suppliers are too expensive

Things I liked: Price/value/quality ratio. To those not accustomed to 10 meter match air pistols the price may seem high. I assure you it is not. While 10 meter die hards might consider this an entry level 10 meter match pistol, it is not. It is packed with features (see the advert for details too numerous examples to list in this review) and the AP20 will be far more precise than most of us will be for a long time to come I.e., hundreds upon hundreds hours of practice. And it is upgradable. I started back in the very early 90's with a Crosman Model 88 CO2 match pistol which, back then, was considered cutting edge in a true entry level Olympic class air pistol. The AP20 seriously surpasses it. I'd like to say it is light years ahead of that most excellent Crosman pistol but that might be pushing it just a bit. Bottom line? The AP20 will out shoot you for a number of years to come.

Things I would have changed: Not a whole lot without impacting the price. That said, I would like to see it supplied with two on-board air cylinder tanks (rather than one, and I wish other air gun manufacturers would take heed of that recommendation) instead of those silly neon barrel slip-over tubes. The plastic adjustable grips are pretty darn good but they could allow for a bit larger hand.

What others should know: An excellent Olympic grade entry level match air pistol for the price along with arguable excellent well thought out features. Do not leave the on-board air cylinder tank screwed fully in place. It will bleed down and empty the on-board tank. I know this for a fact/first hand experience. I thought it was a problem with the AP20 cylinder leaking so sent the pistol and on-board tank back to Umarex for warranty repair. While they did replace one part I was also told by Umarex not to leave the cylinder screwed fully in place on the gun between matches. The cylinder holds the pressure just fine OFF THE GUN but the AP20 pistol will leak the cylinder down over time if the cylinder is screwed fully in place on the gun. In my opinion only, that is no big deal as long as I am aware of it. One should be aware that costly accessories are required to fill the AP20's on-board cylinder... but then if you know anything about PCP air guns you're already aware of that. If not, educate yourself.

  • SoAz from USA asked:

    Why is the AP 20 pistol sound level listed as "1-2 low, medium" and the AP 20 PRO listed as just " 1-low" ? What is the difference between the two?

    • Mark from USA:

      There is very little difference . 1 or 1-2 is pretty much the same. The pistols are the same mechanically.

  • Ryan from USA asked:

    Hammerli-supplied tank does not hold pressure. (Part Number CW 0015). Only way to detach tank from pump adapter is to unscrew the tank from the adapter. Air will leak out from the tank until the tank is removed from the adapter. Is there a better way to maintain pressure in the tank when removing it from the adapter?

    • Mark from USA:

      This tank function is the same for all target airguns pistols and rifles. You turn off the tank without bleeding the air line. This is standard filling procedure. You should not loose much of the fill.

  • Mikhail from Canada asked:

    Hello, I lost the front sight for my Hammerli AP20 Anybody knows where I can order: Triangular front sight, turnable, width 4.0 / 4.5 / 4.9 mm, AP20, #2661535 Regards, MK

    • Mark from USA:

      Walther/Umarex will have parts. They are the importers. You can try Champion's Choice.
