Each link opens the video at the moment quoted.* > For how small this gun is, it shoots relatively the recoil is pretty negligible. > > — [Colion Noir](https://www.youtube.com/watch?v=fEF1CrXXrAA&t=210s) > I like this grip and I don't I like it because it's small and compact and in keeping with the rest of the design language of this rifle or pistol. > > — [Colion Noir](https://www.youtube.com/watch?v=fEF1CrXXrAA&t=222s) > This is noticeably heavier. I will say that there's a lot more weight to this gun um than there is with the Honey Badger. > > — [Colion Noir](https://www.youtube.com/watch?v=fEF1CrXXrAA&t=333s) > This thing is getting hot. But it has more to do with this Texas heat more than anything else. > > — [Colion Noir](https://www.youtube.com/watch?v=fEF1CrXXrAA&t=403s) > It's a fun little gun to shoot.

Compact size and the gas piston system are consistent positives. Owners who specifically wanted a short, maneuverable platform for home defense or suppressor use point to the Rattler's dimensions and piston operation as the main draws. The cleaner operating system (relative to direct impingement) comes up regularly among owners who care about maintenance intervals. .300 BLK versatility gets substantial coverage. The ability to run subsonic loads suppressed is what drives many buyers to the Rattler over 5.56mm alternatives. Supersonic performance is also generally reported as solid. Ergonomics and build quality draw consistent praise. Sig's fit and finish on this platform is a repeated talking point, and controls are described as intuitive for an MCX-familiar shooter. Price is the primary friction point. The Rattler Canebrake is one of the more expensive pistols in the .300 BLK category, and this generates real hesitation among buyers who compare it to lower-cost alternatives. Ammunition cost for .300 BLK also comes up as a running expense consideration. Availability concerns for both the pistol and .300 BLK ammunition during high-demand periods are a recurring practical note. ## Pricing **1 offers available** | Vendor | Price | |--------|-------| | Gunbuyer Com | $2599.99 | ## Similar Products - [Sig Sauer MCX Rattler Tactical Pistol .300 Blackout 5.5" - Black](https://gunsnation.com/p/sig-sauer-mcx-rattler-tactical-pistol-300-blackout-5-5-black/UCE3nOuEd) - [SIG SAUER MCX Rattler LT .300 Blackout Tactical Pistol - Black](https://gunsnation.com/p/sig-sauer-mcx-rattler-lt-300-blackout-tactical-pistol-black/UCE3nP19L) - [Sig Sauer MCX Spear-LT .300 BLK 9" Pistol - Coyote Tan](https://gunsnation.com/p/sig-sauer-mcx-spear-lt-300-blk-9-pistol-coyote-tan/UCE3nOr1d) - [Sig Sauer MCX Rattler Canebrake - Compact Tactical .300 Blackout](https://gunsnation.com/p/sig-sauer-mcx-rattler-canebrake-compact-tactical-300-blackout/UCE3nOark) - [Sig Sauer MCX Rattler .300 AAC Blackout Tactical Pistol](https://gunsnation.com/p/sig-sauer-mcx-rattler-300-aac-blackout-tactical-pistol/UCE3nOWKo) - [Sig Sauer MCX Rattler LT - Compact 7.62mm Tactical Pistol](https://gunsnation.com/p/sig-sauer-mcx-rattler-lt-compact-7-62mm-tactical-pistol/UCE3nP19Z) --- *Data from [GunsNation](https://gunsnation.com)*
