Double Stack 9mm 1911 4.25 Commander Match Grade 416R Stainless Steel barrel. 7075-T6 Aircraft Grade Aluminum Frame. Takes Glock magazines. Series 70. 2.5-3 lb trigger pull. I’ve but probably close to 700 rounds with zero malfunctions of any kind, it’ll take FMJ Hollow points. The folks at Stealth Arms are amazing craftsmen and great customer service. Only selling because i bought another one & i don’t believe in safe queens so I’d rather see someone enjoy this great gun.
