Shooter Guru reviews this budget 1911 for us…. I honestly didnt even know they produced 9mm versions.
The only feed issues with the 1911 have been on reloads with the odd round not returning the next one fully into the breach. The slide spring will take factory rounds down to loads using 3.0 grains of ADI AS30N powder and 135 grain projectiles. So you can download a bit on the standard spring and still get it to cycle.
