EMG Tier One Utility Compact vs WE G19 - Internals Comparison and Compatibility

[@NathanDenekamp]

The reason the blowback units and respective nozzle assemblies are different is because of the rmr mount on the slide of the emg. Emg SAI BLUs are made by WE anyways and the rmr compatible emgs are functionally the same and cross compatible with we mos glocks. I’d bet that if you had the non-rmr compatible emg it would be fully compatible with your WE, including the top seal on the mags.

Hi, thanks for the in depth comparison. I wanted to ask if you'd recommend the Guns Modify Zero Hammer to replace the EMG one on the SAI. I see that in your video your WE g19 has some compatibility issues, do you think they're caused by the trigger arm or the Zero Hammer could play a part in it too? How is the wear on the BBU given the pointy shape of the hammer roller? I am awaiting to receive my EMG SAI g17 and knowing how WE hammers on Glocks tend to get stuck I wanted to already get a valid replacement; I don't know if to get a Zero Hammer or just a regular ball bearing rotor and maybe sanding off a bit the bump on the BBU to further reduce friction; in theory the Zero hammer should completely erase the friction problem when it comes to the return travel of the slide but I 'm concerned about compatibility and general durability of the system. Thanks if you can reply!
