    Slide cuts and finish

    Posted by Alan Klammer on Oct 11th 2020

    I never trust anyone. It’s my nature. I was skeptical that my slide would come back with the finish as well done as the pictures on the website. I have seen a lot of promises resulting in short work. Well let me tell you. Primary Machine did an astounding job. I got the desert camo pattern and their guys are true artists. The slide with the optic which they mounted for me and the new barrel with threat protector was so light with the new cuts Even with the addition of optics , extended barrel and thread protector my G 19 was lighter than plain out of the box. By a lot. The fit and finish was all state of the art. Please put your trust and faith in primary machine. They will not let you down

    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.

    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.

    Simply Amazing

    Posted by Jean 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.
