I purchased the AorA slide to complete a Polymer80, Glock 43 build, after looking at several manufacturers. I chose AorA because their slides are made in the USA, came in a variety of finishes, and are reasonably priced. I received the slide and it showed no tool marks and the finish (Multicam) was great. After further inspection I noticed some small pieces of tape that had been missed and not removed after the painting process. Being a Shade Tree Mechanic I have painted numerous firearms in a camouflage pattern and it’s super easy to miss small pieces of the blocking tape. I used OEM Glock 43 parts in the frame and slide, the OEM slide parts fit into the AorA slide like butter and the slide fit the Polymer80 frame like a glove. I purchased a Backup Tactical threaded barrel and it dropped into the slide and required no fitting. The slide has a RMS (c) cut and after I figured out the proper mounting plate, I mounted a Holosun 507k to it. I had a couple of questions during this process and the folks at AorA were quick to respond. I would definitely buy from them again!
