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.

Things I liked: Very light handling characteristics (can be good or bad depending on individual preferences). This is, to me at least, the TOZ-35's of Air Pistol: it's more forgiving of slight fundamental errors as compared to other High-end AP's I've shot. What should've been a bad "8" with other AP's usually ends up cutting the 9 ring with this one, and shots that should've been weak 9's sometimes clip the edge of the 10 ring. This could be due to the clean, slight-roll breaking 1.9lb. trigger (as it's set from the factory), and maybe the balance of the gun AND the tiny OEM plastic grip not having full contact with my hand so if any slight muscle twitch when I trip the trigger the barrel doesn't seem to move away from its intended aim as fast and as much, which gives you a better "value" shot than other AP's.

Things I would have changed: I think it'd be great if Hammerli offers adult-size grip (plastic is fine) as factory option if buyer chooses so, and still keep it under a grand. For most adults they will find the out-of-the-box gip rather tiny. However, one must take into account (and understandably forgive) that this gun was conceived to meet the goal of introducing youngsters into the Olympic disciplines at the grassroots level without incurring sizable debt in pocketbooks of sponsoring shooting clubs, and still have an uncompromising tool with the potential to shoot world class scores. And it can, as I've shot many 570's with it (and I'm no Olympic hopeful- just another middle age dude plagued with failing eyesight :-)). Personally I'm too cheap to spend another $300+ for a Rink grip, so I'll live with the dinky grips. If you have Male Medium adult size hands or larger, and for the ladies, if you have a decent size hand, may I suggest you purchase aftermarket grip to better suit you. :-)

What others should know: This AP comes supplied with DIN 200 fill adapter. Unless you have your SCUBA tank fitting set up to accept DIN 200, then you have to buy necessary adapters before you can properly and safely fill your cylinder. My SCUBA tank was purchased from the local dive shop and they only have DIN 300 fitting, so the supplied DIN 200 won't work at all. Please do a search for pilkgun's excellent write up on scuba fittings for airguns before you go further. A very required read as knowledge of knowing how to SAFELY set up to fill IS A MUST! All in all, You won't be disappointed with this fine precision shooting machine. :-) Cheers, be safe with proper air filling, and good luck!

  • Robert from USA asked:

    Two questions: 1) I currently fill air reservoirs from a Scuba tank. Does this pistol come with an adapter for a Scuba tank fitting? (I didn't see anything in the PCP Hookup section) 2) Is the Hammerli AP40 air reservoir (your P/N Hammerli AP40 Large Extra Air...) compatible with this pistol? Thanks.

    • Mike from USA asked:

      does this come with the appropriate attachment to fill with a hand pump?

      • Ruth from Canada:

        Take a look at PCP Hookup. It's the next tab over from Q&A. There are several pumps to choose. When you choose the pump, you will also see any adapters needed to be able to fill this pistol.

    To fill your PCP gun:
    1.Pick a source of air shown at right
    2.If an adapter is needed, one will be shown
    3.Add both to your cart to get hooked up
