SIG Sauer M17 P320 ASP, CO2 Pellet Pistol, Coyote-Tan

  • Replica of the U.S. Army M17 Pistol
  • 20rd .177 Caliber Pellet Magazine
  • Full Blowback Metal Slide
  • RMP Belt/C02 Housing Drop Magazine
  • Polymer Frame with Metal Slide
  • Fixed White-Dot Sights
  • Coyote Tan Color
  • Field-Strippable
  • 6lb Trigger Pull
  • Weaver/Picatinny Accessory Rail

Tech Tip: Not compatible with P320 20 round magazines (SIG-AMPC-177-20). The P320 magazine is too long to fit into the M17 housing.

Pulled from the holsters of the world’s most powerful fighting force, the US Army’s newest sidearm is ready for its backyard debut!

Sporting the desert coloration of its theater of operations, this Coyote-Tan M17 uses a 20rd rotary magazine to sling pellets into your target at speeds up to 430 fps. To get started, load up the magazine, drop in a single 12-gram CO2 cartridge and commence dropping targets downrange. 

Each SIG M17 CO2 Pistol is field-strippable and includes a responsive blowback to bring the most realism possible to your plinking sessions. Ready for rapid-fire action, shoot with white-dot sights or add accessories to its Weaver rail to make this historic sidearm your own.

Want to get a backyard friendly feel for this historic sidearm? Take hold of your own SIG M17 and bring the battle to your backyard range.

Things I liked: I really enjoy this handgun from Sig. Terrific set up with the CO2 and mag. Using Sig Match Ballistic Alloy pellets it is the most accurate Sig pistol to date for me. I have two P226's. one P320. Very happy with this M17

Things I would have changed: The only small annoyance, being left handed, is the mag release button is in the way of my hand. I like everything else.Fun shooter.

What others should know: Fun six to ten yard shooter.

Things I liked: I just received the m17 probably as usual no problems with shipping it came beautifully boxed as far as the the gun goes I really can't say anything bad the new system for the CO2 is absolutely genius it makes it a lot easier to put CO2 in I was a little worried about losing CO2 upon mag changes there is virtually no loss of course I didn't have magazines to change I just pulled out the mag and it gives off a slight amount but nothing that hurts the FPS trigger pull is great I get it consistent4 pounds pull P you lol its smooth and crisp accuracy is great the sites are great like I said I have nothing bad to say fives across the board get one quick before they're gone

Things I would have changed: Absolutely nothing the weight the feel is phenomenal I literally can say Sig really surpass themselves I own both P226 mk and the thing that I didn't like about them was the ejection port well Sig fix that with the realism of the new one great job saying it gives it that more realistic look and you want to add this to your collection once again not to be redundant there's nothing to change thumbs up Sig

What others should know: Like I said not to be redundant get one before they're gone and you have to wait because once the word gets out everybody's going to want one

Things I liked: Beautifully made piece. Very realistic in feel and appearance. Great value for money. Reasonably accurate. The best CO2 loading system in the industry.

Things I would have changed: Although the pellet magazine works, it's advanced via the trigger pull which makes the trigger this guns Achillies heel. WIth an 8lb trigger pull (this was after working on that pull, it was initially 9+lbs) that's long and gritty, it's hard to predict when the gun will fire. For many this isn't an issue, since aiming a handgun at 10 yards is highly overrated by most pistolero types. These types of handguns are meant to be Point N Shoot as fast as you can, and this gun is capable of delivering on that. However, if you want a highly accurate pistol, you'll want to look elsewhere since the trigger pull on this guy will always be a limiting factor.

What others should know: Mounting a laser pointer sighting aide to the Picatiny rail will greatly simplify aiming and certainly improve accuracy.

  • Keith from USA asked:

    About how many shots per CO2 caplet will this deliver?

    • Jordan from USA:


  • Arthur from Canada asked:

    Is the trigger double action only, or double and single? Is the trigger pill shorter on the second and subsequent shots. Thanks.

    • Tyler from USA:

      I would call it a double action as the trigger also cycles the magazine belt.

  • Daniel from USA asked:

    What size grip module is this manufactured with? Are alternative grip modules available for this model like the real M17?

    • Tyler from USA:

      I believe the firearms come with the medium size module, I would say this is a close representation of that. I have not heard about Sig planning to offer other modules for the ASP line.
