i make business with all the majors: glockparts.com- glockworx-glockstore-rockyourglock
rockyourglock phantom triggers can't be compared to fullcrum from glockworx, they dont provide the adjustable housing and something similar to the GW V4 race connector .only the adjustable trigger pad-bar although it work great and gets you a finely tuned over-pre travel ; you still have to put a spring kit and a fine connector in the upper-lower to get a very light trigger break ,again the glockworx comp spring kit and V4 race connector are ahead of all,even the ghost reduced system kit . shipping is an OK factor with RYG,nice array or sights and slide release levers,recoil rods and titanium parts as well.
glockworx has the best service and shipping time frame of all by a full lenght they build themself the very best and finest trigger gear of them all.
glockstore is filled with very nice offers and have the largest choice of parts and accessories for glocks, generaly they charge more for comparable items than the other GW and GP . also, glockstore charges a premium in shipping handling fees compared with the others.
glockparts.com carries what realy sell, the basics. however it's with them i started to get nice glockeries online mostly meprolight sights and recoil rods . i got very,very nice LPA SPR adjustable target sights for my «g35 and i'm currently waiting for the another set who went BO just prior to ship. those three are the most reliable and serious glockeries retailers.
