PRECISION BRED THROUGH PROCESS
Proudly Made in America | OA Defense’s production and assembly process relies on precision engineering and machining, multiple rounds of stringent quality control, and a team of skilled techs and gunsmiths who work together to hand-fit and hand-finish the critical engagement points. Each assembled pistol then goes through a multi-point inspection and test firing process prior to being released for cleaning and shipping.
DELIVERY TIMES
OA Defense strives to deliver pistol orders within ninety (90) days of ordering. The OA production team goes to great lengths to ensure that lead times do not exceed this timeframe, but variables do exist that are outside of our control. If the production team feels that additional time is needed to ensure that your pistol is leaving our facility in perfect condition, then we will contact you with an updated delivery estimate. For questions regarding lead times and delivery estimates beyond the standard 90-day window, please contact us.
Barry Collins (verified owner) –
I have the compact and absolutely love it. The edges of the safety are a little sharp but nothing I can’t get use to. Well balanced and the trigger is amazing. It’s not a competition trigger but perfect for carry. The takedown isn’t quit as easy as the instructions though. The slide stop doesn’t push out readily from the right side but isn’t a deal breaker. The gun cycles smoothly and after 1k not a single malfunction. The wait was long but worth it.
