Sig Sauer P320 M17 CO2-Powered .177 Cal Semi-Automatic Air Pistol with 20rd Pellet Magazine Included

Great pistol with good grip feel, and weight and balance (suppose to replicate the real M17). Mag is really nice with lever for loading CO2 (no tool required!) and holds separate 20 round .177 pellets in rotary mag (buy extra rotary mags!). Trigger pull is clunky because of the rotary mag, so place drops of oil (pelletgunoil) in rotary mag (rotate mag many times as you go) and oil on trigger assembly and slide. That smoothed out the pull quite a bit! The pistol isn't a full blow back; slide goes 1/4 to 1/2 back but still gives you somewhat the feel of the real thing (it was cold the day I was shooting). Power was on par with other CO2 pistols and accuracy was pretty good using a red dot sight, but I'm not a very good shot with a pistol either.

This thing is a whole lot of fun. It feels solid in your hands. The blowback is well done and gives you something consider when blowing through magazines.The magazines, by the way, are perfectly done. Easy to remove and load, 20 rd capacity, and it just plain works. I've put about 500 rounds in and have yet to have a single jam (USE ROUNDED PELLETS - anything long and pointy will get stuck.Good accuracy, sufficient FPS for plinking and target practice, and about 50 rounds per CO2 cartridge (which is very good considering the blowback). Also, the FPS won't drop off noticeably until the very end. The first 40+ shots felt just as powerful as the first.Killer looks and modern style. The pica tinny rail allows you to add laser or flashlight to the bottom rail. You can also get an adapter to add a top rail, giving you access to reflex and red dot sights (this is well worth it).Overall, a very fun gun that performs well and is great for practicing and learning what the real thing is like. Sig Sauer is a great company that makes killer stuff.

This thing is pretty close to the real p320. I love that the co2 is in the removable magazine. It’s so fun to shoot. The trigger pull is a bit clunky since it has to manually cycle the pellet track, but easy to get used to. Looks great, feels great

This pistol is a great training aid. I wanted a CO2 pistol which was as close to my real pistol as possible. This pistol combined with the Sig Air red dot sight fit that ticket. I have been able to consistently shoot 2 inch groups at 10 meters while standing 2 handed without support. It can shoot an inch or so high with a new cartridge and then an inch or so low as the cartridge is on its last breath. The safety, mag release and slide lock are the same as the real version. I have found the 7.4g wadcutter from Crossman to be the best fit for me. When 9mm are costing 40 cents a trigger pull, this is a much cheaper option that allows you to shoot in your home without going to the range. That makes it easy and fun to train each day.I want to take a second to address some concerns expressed by other negative reviews.1. Leaky CO2 . This also happened to me at around 700 shots. The o-ring in the magazine failed. There are a number of Youtube videos showing how to replace this o-ring. The smaller of the two appears to be 6mm OD and 3mm ID. I can't confirm this as I chose to contact Sig Sauer customer service and they promptly responded and sent out a new magazine. Take note - this has a full one year warranty.2. Pellets plug barrel. I have only had this happen twice. Once when the CO2 was on its last breath and another time when an apparent malformed pellet got stuck. Each time, I pushed the pellet out with a wire and continued to shoot without further issue.

This is a awesome pellet pistol, looks and feels real. Good performer. I added a laser/flashlight set up. This is my second sig air product, I have the mcx also this pairs up well. No jamming on either.My advice would be to to get an extra magazine ( sig sells them on their website) and also get two spare magazine inserts. You get 40 hard hitting shots per co2 with M17 pistol, then they get a little weak. You lose a little co2 when you drop the mag. You'll get 60 shots per co2 but the last 20 will start to drop.With the extra co2 magazine housing and a two pack of the pellet mag's, make this air pistol extra enjoyable..Very happy with this, well made. Sig is on a different level producing air pistols and rifles.Edit: Well I'm not as happy as I was two weeks ago...this air pistol has failed. After popping out around 1000 rounds the co2 magazines stopped sealing, every time I loaded a co2 the air would just leak out... that goes for the extra one I got from Sig too. Very disappointed. Sending it back. It's a shame because all my other Sig products work very well.

I hesitated to get it for some time because of the reviews about jamming and accuracy issues. Nevertheless I decided to order it and try it myself. I figured that in the worst case scenario I would return it and that would be it.Yes, coming out of the box it jams a lot but this is how I got that fixed:- Lube the mechanism and the feeding belt- Use wadcutter pellets only and make sure they are sitting all the way down ( use a tool to push them until you hear a clear click sound)- Put it on safe and dry fire it until you start feeling that less force is required to pull the trigger, it feels smooth, and it no longer gets jammed. While doing this eject and insert the magazine as if your were reloading. (I probably dry fired it 1500 times and NO CO2 cartridge is required while doing this!)Again, coming out of the box it fires low and you can't adjust the sights but this is how I improved the accuracy:- Paint the white dot on the front sight with black ink (I used a sharpie)- Paint a white dot below the original dot.After this I shot 225 rounds (75 per cartridge) with absolutely no jams and much better accuracy.Beautiful replica. I'm keeping mine!

It worked great for a couple months then the magazine wouldn’t spin so I got a new magazine. The same thing happened and made the pistol unusable. Also, the gasket for the air broke so immediately when you put the CO2 in it just emptied and leaked. I have a road problem so I need a reliable pellet gun. This is not that one.
