Sig SauerP226 MK-25 CO2-Powered .177 Cal Semi-Auto Black Airgun Pellet Pistol with 16rd 8x2 Rotary Magazine

Hoo boy, this is a fun gun.As I mentioned in another review, my caveat is that I don't own firearms, but have used many. I have not owned a SIG but have handled the real 9mm version, and it's completely spot on.If you've been keeping score, this isn't a licensed replica from an airsoft company (like the KWC P226 X-Five, not to be confused with the X-Five ASP), but an actual SIG Sauer gun designed by them in the US and produced in Japan, sold, warranted and serviced by SIG. They've been ramping up their homegrown airgun line under the Advanced Sport Pellet brand–as they put it, "it shoots like a SIG because it is a SIG." This particular model is based on the 226 issued to the US Navy SEALS, hence the anchor on the barrel.Fit, finish and appearance:A friend of mine has a 226, and there's very little difference at first glance. First, owing to the nature of an airgun, there's a few omitted functions. The slide lock is non-functional and the ejection port is molded in. Other airguns, like my KWC 1911, feature these and field-stripping capability, but SIG decided these are superfluous to the operation, though included them for visual accuracy. It's a ding for accuracy to the prototype, and makes for a bit of a pain checking if a round is chambered, but does not detract from operation. The exterior is painted rather than blued with a flat (not matte) black, and markings/logos/warnings are molded in rather than etched or screen printed. The finish is paint, but looks very close to SIG's Nitron finish—just don't scratch it.Where it lacks in these small details is makes up in just how tight the construction is. The gun is full-metal with blowback and a good kick. Report is LOUD and there's a flash of CO2 vapor from the muzzle when fired. The slide doesn't return as far back as the aforementioned 1911, but has enough recoil that you feel it. Remember, this is intended as a high-end training pistol. The barrel has a threaded extension and cap for a mock-silencer, which Pyramyd sells but Amazon and SIG don't as a kit. Still, it adds some realism.The weight is heavy, within ounces of the 9mm prototype, even with the plastic mags. Slide and barrel, at least on my model, are very tight; I know earlier pieces when this first came out had quite a bit of slop. The grips are plastic with a big "P226" banner on them and should be replaceable with aftermarket versions.Accuracy and Velocity:It's worth mentioning that this is a pellet pistol, which opens you up to a lot more ammo options than a run of the mill BB gun. The mags do accept BBs, have a marking indicating so, and a retaining magnet for loading them, but it's highly discouraged with the rifled barrel. You'll lose a lot of accuracy and tear up the barrel, so suck it up and buy some lead or alloy pellets to try out. The original stated velocity was 500+ FPS, but after independent testing they brought it down to around 450, but that's still only with the lightest aluminum pellets. It seems to like ones in the 5-6gr range.At 15', it's dead-on. Further than that, there's some drop of POI, depending on pellet weight. Sadly, the sights, though drilled with white dots, are plastic and don't readily appear to be replaceable or adjustable; you'll have to go for the X-Five ASP for that. They're otherwise serviceable for quick sighting if you aim up a bit at longer distances. Windage is pretty much spot-on. There's an under barrel accessory rail and I mounted the IMI Defense bridge mount (a SIG copy, down to the logo) and red-dot sight and getting good results. It's far from a competition pistol, but far, far more than just a replica firearm that goes bang. Shoot slow and it will reward you at the target range, or, shoot as fast as your finger can go and blast those soda cans away.At 10m I've gotten best results with H&N Field Target Green and and Crosman Destoyers so far. It does load Gamo Raptors and Prometheus pellets.Operation and handling:The magazines are plastic 2x8 GAMO copies and leave something to be desired, considering the heft and finish of the weapon itself. Still, they work, and while they aren't as innovative as SIG's newer belt mags, 16rds total is nothing to scoff at. They'll load BBs, as mentioned, and any standard pellet short of sabot and weird composite hunting rounds (which this really isn't made for anyway).There's a lot of reviews out there lamenting the mags' propensity to spring out and not stay seated. I thought I was lucky with mine having a nice firm grip on them, but after about 300 rounds, it happened. The problem appeared to be with the release button not returning fully, and a few drops of Pellgunoil solved it for now. Try that before returning your piece.The CO2 loading is a real innovation here. Stick the cartridge in and slap the backstrap together and you're ready to shoot. It takes a good amount of force and swiftness to close, or else you'll lose a lot of gas. Getting them out is a bit of a challenge and I've resorted to holding the gun upside down and tapping the front strap, to the concern of my neighbors at the range.The left-side safety also functions as a decocker, which is a nice safety feature common to the prototype. My local small-bore range doesn't require chamber flags or the like for air pistols, but with propellant in the grip and no way to check the chamber state, it's nice to know accidental discharge is highly unlikely.The trigger action is peculiar and takes a little getting used to. It's nominally DA/SA, but has a long throw and audible (but not tactile) click halfway through—that's the magazine advancing. Pull through this or you'll advance the mag without firing. Conversely, in rapid-firing, you must release the trigger fully, past the reset point. Otherwise, the pull is smooth and fairly light. You wouldn't be able to tell dry firing, where it's much jerkier.In conclusion, this is an excellent machine, and probably the best you can get before heading into the $400 range, which is mostly populated with 10m target shooters. As something made by an actual firearms manufacturer, it's the pinnacle of realism for both firearms training and all-round shooting fun. Compared to other repeating pistols in the ~$100 range, this is the best of the best, and I'm excited for what SIG comes out with in the future. If your tastes lean toward target and range shooting, definitely look into the X-Five ASP, which is the same gun with adjustable sights, modified trigger, and improved mag, but this one's just as accurate and powerful. Shortly after I bought this, the X-Five was stocked again and I had a pang of regret—that quickly dissipated after shooting it.

This is a heavy gun. Very sturdy, and heavy. And accurate.

This pellet gun will not hold the co2 cartridge charged, it hisses out . I’m seriously disappointed. I’m trying to teach my son to be responsible and the gravity of the pellet gun first. How can I show it when the POS WONT HOLD AIR? Do not buy!!!!!!

This SIG SAUER P226 pistol is a blast to shoot. It feels like the real thing. I bought two extra magazines and filled the three magazines. I fired all 48 pellets without any jamming issues. Accuracy was good and it felt very realistic. I did notice you must relax the trigger pull completely before firing the next round because the trigger indexes the magazine to the next round. If you fail to release the trigger back to zero position, it will not index the magazine to the next round. Not an issue, just something to get used to. Once I did that after every shot, it worked flawlessly. The sights are great but not adjustable. My shots were slightly low and to the right shooting one handed but that might have been me. I plan to test it with a bench rest and properly check the accuracy.

Awesome quality. Perfect for getting rid of our frog situation. Get the laser for under barrel. So far so good. Perfect. No issues. Performed as intended.

Further updates gun was awesome it quit working im a physicist and I can't fix it and no return for some reason i was under the impression that prime all non perishable items especially 135 dollar bb guns could have a return and replacement but no return but inder is true this is January 10th updates ive had it a few weeks but i shoot a lot if the offer a fix its broken inside i hear something the valve seal for co2 is fine Trigger is moving nothing loose and floppy !!!crosman or any co2 with a thin foil steel seal not the crooked looking older crosman capped co2s and lube them properly but also lube the roller wheel system for co2 cartridges and make sure there smooth enough alloy cartridges to slide up I rock them and get the fit with barrel at a flat or parallel angle to ground straight up and I feel it fit then a quick squeeze it's insanity on accuracy for a loose floated barrel and it has a kinda so so magazine its coman works well for lead but if you use hard copper it wears the slotted port for pellet retention but for a truly floating barrel and kinda huge but standard pistol sights is very accurate though I'm worried about the slide becoming more and more loose so I oil tracks all internal parts and moving parts with NON petroleum based oil I use rc 50 weight shock lube always try to smooth the cot tip and gently apply a small amount of lube for seals I do believe crosman co2 bulks are a little dirty oil and co2but they work on a budget but if you can get better quality ones if you only shoot this on co2 and can afford now I put a laser and light on it I'm a firearms enthusiastic shooter and bullestician very skilled in firearms and pretty skilled with pneumatics I have am physicist this had very decent POWER FOR a blowback I'm using crosman pointed lead h&n is my favorite but I shoot a lot I have 5 gamo rifles a lot of pistols and firearms if you intend to small game hunt I suggest a rifle break barrel 22 or 17 gamo redirect if a pistols desired a Diana chaser or bandit is great and easily accessible powered up by spring spacer or replacement to slightly stronger hammer spring crosman 2240 is excellent if v you really want a different product crosman custom allows a 13xx a 2240 AKa 2300 to be built cheaper than you can online depending upon your desired modifications but Diana chaser is much better quality stock though a stock 2240 is more durable unless you put a barrel band on Diana chaser the rifle kit is insane value this sig is also a good job its extremely relatively similar to a 380 or heavy 9mm in recoil but either way it realistic to a t not for children to take near public I'm a expert and this is identical to the real or firearms version of sog p226 common government issued pistols you would have to be close to tell the difference between these if you could at all most could not and they have 22 similar bore sizes and the other sigs atleast are using recessed barrels so way to realistic if a officer sees you wheel ding it near public but all and so far a decent gun furth
