NOTE: The owner's manual states that this has BAX Hop-Up, but it does not.

Although this gun appears to have a half-cock safety, the pistol does not function like that and would need to be fully cocked and on safe to be carried at the ready. Carrying this pistol half-cocked with the safety on may cause accidental discharge and is not recommended.

Learn more about the SIG Sauer P226 in Dennis Adler's Airgun Experience Blog.

An incredibly realistic airgun that's a great all-day plinker and suitable for maintaining firearm proficiency. The slide moves and the gun feels and handles like the P226 firearm. You just can't go wrong with this pistol!

Things I liked: I liked everything, one of the BEST guns you can buy and has a real characteristics to it, Ive had mine for almost a year and still runs exceptionally good, out of all my air guns this is my favorite for realism to action, I also changed the spring so I can have a harder kick back

Things I would have changed: Not a thing

What others should know: Its one of the best air guns you'll ever buy I guarantee it

Things I liked: This gun is AWESOME, it is accurate as heck!!! I shoot it at 10 meters and it shoots a 6 shot group roghly the size of a quarter. The blowback is nice as well, id compare it to about a 22lr in has good weight to it and you can field strip this gun as well for easy cleaning, overall i love this gun i get about 3 magazines before i notice co2 running low

Things I would have changed: Loading the magazine is a pain sometimes, the spring is pretty stiff and the bbs are a struggle to insert, other than that tiny thing its a good gun

What others should know: Buy a spare magazine for it, more the merrier

Things I liked: Sighting For all three ASP pistols, some reviewers report that the fixed sights were significantly off . My P250 shot to aimpoint with Crosman Competition 7.4 gr wadcutters. Velocity The Sig Sauer packaging says up to 500 fps”. The PyramydAir website says average = 401 fps with 5.25 gr pellets; their test of my P250 with 7 gr pellets gave ave = 371 fps, range = 421-335. Grip size The P250 firearm has 3 grip modules. The P250 ASP has only one; it fits my small hands OK (glove size men’s S or M). CO2 Use Average 60 shots/cartridge. Trigger Ronald reports (review 2016-06-05) that the P250 ASP is DA/SA, unlike the P250 firearm, which is double action only. Dennis Adler’s otherwise very useful PyramydAir review incorrectly states the ASP is DAO like the firearm; mine is DA/SA; and the packaging says “Single/Double Action Trigger”. DA - lifts 8 lb, breaks 8½ lb, pull = ¾” SA - lifts 5¾ lb, breaks 6 lb, reset = ¼” Overall: A very pleasing pistol. No problems in 500 rounds.

Things I would have changed: (1) Fixed sights: For this pistol and other fixed-sight pistols, it would be very useful if PyramydAir offered a testing service to check whether the sight alignment was reasonably accurate; Id be happy to pay for this, perhaps as an add-on to the 10-for-$10 service. I had a lengthy e-mail exchange about this with helpful people at PyramydAir and thought I had arranged for a sighting test, but the 10-for-$10 Test Certificate showed no notation about testing sighting. My P250 is sighted fine, but it would have been nice to get the test. (2) Realistic function: Many reviewers note that the three Sig Sauer ASP pellet pistols lack useful features that are found on many blowback BB pistols like the SIG Sauer P226 X-Five Open Combo: complete controls, slide lock back on empty, realistic magazine changes, adjustable sights. I'd be happy to pay more for a pellet pistol with these features, 50% or even 100% over current list price.

What others should know: It is very useful to have additional magazines; they come in a two-pack for $20 at PyramydAir:

  • Vidal from Trinidad and Tobago asked:

    Hi. So without even using it much (maybe like 200 rounds), mine had to be continuously manually cocked to fire; apparently the little notch for the trigger arm to grip onto the hammer was worn. So I foolishly decided to open it up. Like really open it up. I now cannot put the hammer assembly back together and even if I am successful, it still has the worn part. Is there anywhere I can get a replacement hammer assembly to buy? Or at least instructions on how to put it back together?

    • colin from USA asked:

      Where can I buy a new air nozzle for this gun?

      • colin from USA asked:

        I need a new air nozzle for this gun as the stripper is worn and won't put a new B&B in the barrel so l have to load one at a time! Does anyone know where to get parts for this gun? It is out of warranty
