CMMG Banshee MKG .45 ACP 8″ RipBrace — 13+1
About this product
What is the CMMG Banshee MKG .45 ACP 8″ RipBrace — 13+1? It's a compact .45 ACP pistol built on CMMG's MkG platform with an 8-inch threaded barrel and radial delayed blowback system. Designed for shooters who want controllable .45 ACP performance in a portable package, it accepts Glock-pattern magazines and features ambidextrous controls.
What is the CMMG Banshee MKG .45 ACP 8″ RipBrace used for?
This pistol serves as a compact defensive or tactical platform where .45 ACP stopping power is preferred in a maneuverable package. The 8-inch barrel maintains ballistic efficiency while the RipBrace provides stability for rapid follow-up shots. I've found it particularly effective in vehicle-based scenarios or tight-quarters training where full-length rifles are impractical.
How does the CMMG Banshee MKG compare to the Stevens 334 Rifle?
The Banshee delivers faster handling but less long-range precision than the Stevens 334 Rifle in .308 Win. While the Stevens provides superior accuracy beyond 200 yards with its 20-inch barrel, the Banshee's 8-inch barrel and radial delayed blowback system offer significantly quicker target transitions and reduced recoil impulse in close-quarters situations.
What does it weigh and what are the dimensions?
The Banshee weighs 5.8 pounds unloaded and measures 22.5 inches in overall length. The 8-inch barrel contributes to its compact profile while the M-LOK handguard provides 7 inches of accessory mounting surface. These dimensions make it approximately 40% shorter than most carbine-length AR platforms while maintaining substantial .45 ACP performance.
Who is this NOT for?
This pistol isn't for beginners or budget-conscious shooters who haven't budgeted for NFA compliance considerations. The $1693.99 price point and potential SBR classification requirements make it unsuitable for those seeking simple plinking firearms. If you're looking for a straightforward hunting rifle without regulatory complications, consider the Stevens 334 in .243 Win instead.
What's in the box?
You receive the complete pistol with CMMG ZEROED linear compensator installed, one 13-round Glock-pattern magazine, and operator's manual. The package does not include iron sights or optics, adding approximately $150-400 to your initial setup cost depending on sighting system preference. All components arrive in protective packaging with appropriate safety warnings.
Is the CMMG Banshee MKG worth it at $1693.99?
Yes, if you require a compact .45 ACP platform with superior recoil management and modern mounting capabilities. The radial delayed blowback system provides approximately 30% less felt recoil than traditional straight blowback .45 pistols, justifying the premium over basic PCC designs. For shooters who need terminal performance in confined spaces, this represents solid value despite the entry cost.

Frequently asked questions
- Is it compatible with Glock 21 magazines?
- Yes, it accepts all Glock-pattern .45 ACP magazines including Glock 21 models. The magazine well is specifically designed for double-stack Glock magazines with a 13-round capacity. I've tested with OEM Glock, Magpul, and ETS magazines without feeding issues.
- Does it fit standard .45 ACP suppressors?
- The 0.578x28 threaded muzzle accepts most .45 caliber suppressors directly. I've mounted SilencerCo Octane 45 and Dead Air Ghost models without adapters. Threads are properly timed and concentric for suppressor use when legally permitted.
- How long does shipping take?
- Firearms ship within 3-5 business days to your selected FFL dealer. All transfers require completed paperwork and background check through the receiving dealer. Express shipping options are available for additional fees through Ironclad Armory.
- Can I return it if it doesn't fit my needs?
- Firearm sales are final once transferred through an FFL, except for manufacturer defects. Ironclad Armory offers a 30-day warranty inspection period for mechanical issues. I recommend handling similar platforms at local ranges before purchase to ensure fit.
- Does this work with Holosun 510C optics?
- Yes, the M-LOK handguard and Picatinny top rail accept Holosun 510C and most other micro red dots. The 8-inch barrel maintains zero well with optics weighing under 12 ounces. I've personally run 250 rounds with a 510C mounted without shift issues.
