The O.Z-9 Modular Build Kit (MBK) offers complete customization to build your O.Z-9 from the ground up.

The O.Z-9 Modular Build Kit (MBK) offers complete customization to build your O.Z-9 from the ground up. Using compatible ZEV components, you get to pick and choose your ZEV slide, ZEV barrel, ZEV O.Z-9 grip, and ZEV O.Z-9 magwell to build the O.Z-9 that best fits your needs, whether its duty, concealed carry, competition or a week-end range gun.

Machined from a single block of 4140 alloy steel, the patented O.Z-9 internal steel receiver reduces the flex associated with polymer frames, has an integrated locking block and longer slide rails which provide more contact with the slide. This amounts to less felt recoil, less muzzle flip, faster follow up shots and improved accuracy.

Superb craftsmanship

We recently received our first OZ9 Combat with both a standard size and compact grip. Our instructors have been putting the weapon thru it’s paces. The heart of the weapon is this trigger assembly and steel frame. The thought, design and execution of this innovative modular system is superb. We can drop it between the two grip sizes by removing one pin and have a choice of a full size grip or a compact ccw in less than a minute. No problems reported and it’s a tack-driver. Zev continues to impress. Can’t recommend them enough.

Very Impressed

I managed to get this on sale for a really great price. Granted, the V2 should be launching soon but, I cant complain for how good of a deal I got on this. In my opinion an MBK is the way to go... You can build it out exactly how you want and if you live in Washington no 10 day wait on BGC! (Only downside is no standard warranty). With the conversion slides there is no reason to get a standard MBK unless you already have a bunch of gen 3 17/34 parts laying around. The extra weight from the steel frame makes it better than a regular Glock and the ability to swap grips is even better! Modular frames are the future of handguns in my opinion and Zev did an outstanding job designing this & you get what you pay for when buying from them... Zev also has awesome customer support and answered any questions fast. Excellent product!
