X-Five .177 Caliber Gun

Pretty good gun after slight alteration. It kept jamming after just a few shots then I looked closely at the clips and they are made with a slight flaw so I took some professional finger nail trimmers and shipped off a bit of the plastic on all the magazines and that fixed the issue.. great to shoot now. Altho sometimes a pellet still gets jammed but not nearly as often so I use bbs most of the time with no problems

Pros (and there are more than listed here): Realistic look and feel makes it a perfect training weapon. ADJUSTABLE REAR SITE!!!! Sig's lever gas cylinder loading system avoids the waste of screw-in types. 20 round belt-fed magazine separate from the version used in the M-17 model reduces CO2 waste. Longer barrel helps with tighter shot grouping. Functional slide adds to the look and feel (though wastes CO2 to accomplish that). Pic rail for lights and/or laser sites. Rifled 5" barrel for better accuracy. Ambidextrous safety (requires a bit of breaking in). Cons: Decorative hammer stays cocked until slide hasn't the gas to push it back (though it is a nice reminder that the weapon is loaded). Unlike other P320's, the slide cannot be removed, a serious drawback should a round jam. Cannot be disassembled for proper cleaning. For women, it can be uncomfortable to carry in a belt holster, I have to use a drop-leg (shoulder holsters are not practical for a weapon this large and heavy). Okay, those are the highlights. The longer barrel makes this one more accurate than my M17 version using the same style and weight pellets. Unless you want to destroy it, don't even think about using BB's. I get good half-dollar groupings at 20 meters using the iron sites (front fixed, rear adjustable for windage and elevation), which is good enough for me. As I'm both in a wheelchair and live in an area with a coyote issue, this gives me a way to convince the critters I'm not meals-on-wheels. It also works as a less-than-lethal tool for self defense, preferred to the alternative while living in an apartment with thin walls. I have found Premier Destroyer pellets 7.4 gr work best for me, lighter ones cause wider shot groupings, heavier ones reduce effective range. The pellet design gives me the penetration of target I need to avoid being a snack. THIS IS NOT A TOY. It looks very real, especially to cops, so don't "play with it" or allow minors to operate without continuous supervision. As pellets can do odd things for all sorts of reasons, always wear eye protection. Always handle as though the real deal that is loaded and the safety is off. Invest in a trigger lock to eliminate all sorts of potential regrets. I use a lock-box as well, since I already had it. Keep it properly maintained (insofar as the inability to disassemble allows) to avoid damaging the weapon or causing injury. Be sure to remove CO2 cartridge before attempting to clear any jam, and when clearing it use only a .177 (4.5 mm) cleaning rod.

I wanted to like this pistol. It looks great and has significant heft. But 1/2 way through the first CO2 cartridge the thing jammed. It wouldn't fire, wouldn't advance to the next pellet, and the magazine wouldn't come out. There's no Sig Sauer sanctioned way for the owner to fix it. The user manual says that if there's a jam, you have to send it back to them for repair. What??? At this point I wanted to just return the thing as it was brand new, but doing so through Amazon was very difficult. The item cannot be returned! Amazon eventually took care of me, but for a while it looked like I was going to be stuck with a $100+ paperweight. Jams in Sig Sauer air pistols are a known and pervasive issue. I should have done my homework before buying. My advice is to try a different pistol from a different maker, or buy this model from a store that allows returns. Sig is trying to get into the serious airgun world, but this entry is a failure. Too bad, as they make excellent firearms and have the potential to make quality airguns.

Things I liked: Weight and balance were realistic, although maybe too much so. This is a VERY heavy pistol. Accuracy is very good and it has adjustable sights, although missing white dots, which I like. Black color fits the looks of this BIG pistol. High 20 pellet capacity so you can shoot for awhile before needing to reload. Very nice, solid blowback. Firing a shot results in a loud report that does not change whether there is a pellet in the belt at the time, or not. Performance Specs: Using Crossman Permier 7.4 gr Wadcutter pellets, Max fps=348, Min fps=255, Average fps=292.2, SD=32.1, fpe=-1.99 Using H&N Trophy Greens at 5.71 gr, Max fps=399, Min fps=307, Average fps=358.4, SD=29.7, fpe=2.02. Pistol weight is 3.0 lbs (per advert) and was too heavy for my small scale to measure. Trigger pull in single action was 2 lbs, 14 oz, which is not too bad, but DA pull is 5+ lbs. Things I would have changed: I like the weight of this pistol but it is too heavy, in my opinion. I suspect long shooting sessions could become tedious. Shot count is low because the blowback needs lots of CO2 to move the heavy slide. performance does not meet advertised spec of 430 (or 420 fps, depending on where you look). Using standard 7.4 gr pellets, my favorites, or using lighter non-lead alloy pellets of 5.71 gr, which are needed to get even close to spec. Only the front sight has a white dot for sighting but the rear sight is black with no helping white dots. Loading the 20 pellet belt is a little awkward because the belt will 'bunch up' unless you rotate carefully. What other should know: I think Sig Sauer could have done much better with this pistol. The weight is far heavier than it needs to be at 3 pounds (twice the weight of my CZ75 P-07), but is unavoidable, since the pistol is all metal and is very large. Some might find this pistol hard to use because of its size and weight. The sights are adjustable for windage and elevation but it took me some time to find the right adjust for relatively close shooting. It normally wants to shoot very low (about 4 inches low at 10 feet) so you will need to adjust to compensate. It is worth the time it takes to achieve accuracy. After adjustments and some practice I was able to put a majority of shots into a 2 inch target circle from 10 feet, but from 18 feet I was lucky to hit 3 out of five into that circle, probably my fault because the pistol is so heavy. If you can handle a pistol this size I think you might find it perfect for you. You get a lot for your money and there are few CO2 pistols out there that will come with adjustable sights. Give it a try. The price is right.
