  1. Perfection 5 Star Review

    Posted by on Jun 20th 2017

    I've had slides milled by a lot of different places. Even the high end names left some sort of blemish somewhere on the slide. Nothing like that here. These guys knock it out of the park. I cerakote a lot of pistols and rifles and i send all my mill and Cnc needs to these guys. It's always perfect.

  2. Solid 5 Star Review

    Posted by on May 12th 2017

    Well executed machine work. No sharp edges, burrs or machine marks. Cocking serrations have sufficient grip without being too aggressive. Front cocking serrations are a big plus for a RMR equipped pistol. The detail of the design is readily apparent and pleasing to the eye. I also feel that the design removes the right amount of material without sacrificing structual integrity. I do not foresee the potential for a slide failure with this design. I am most pleased with the work Primary Machine performed and would recommend without hesitation.

  3. Simply Amazing 5 Star Review

    Posted by on Mar 16th 2017

    Primary Machine has done a flawless job on my Glock 40 10mm Long Slide. I originally wanted the xtreme cut, but had second thoughts because i wanted to retain some strength for the hot 10mm loads. This slide looks classy and not over done. I got the tini finish on the barrel, and it peeks out just enough on top to have that bling factor. Cerakote is done flawlessly, and they replace the channel liner, some companies dont do this. Their logo is pretty cool and its done in a way where its not too intrusive. So far this company had the best price and turn around time. other companies will charge double and also a 3 month wait. I highly recommend this to anyone on the fence.
