Please hold off on purchasing/installing the Apex Glock Trigger on a G43 until this problem has been resolved. Details: I was all excited when Apex Tactical announced that they finally produced a replacement trigger for Glocks. Being familiar with Apex Tactical's solid reputation for quality trigger products for the Smith & Wesson M&Ps, I didn't wait for the "normally allowed" real world debugging of a new product by the general public. I received my Apex Glock Trigger (no trigger bar available for the G43) a couple of days ago and finally had the time to install it this evening. Lets call it a complete "FAIL" at this point in time. The removal of the G43 trigger shoe pin from the trigger bar was very easy (thanks to a simple tip given to me from HGxyz) and my factory trigger shoe was not "completely busted". I might have to reinstall this trigger shoe until I can get a replacement factory trigger/trigger bar or (hopefully) if Apex Tactical can quickly resolve the design problem. The installation of the Apex Glock trigger on my factory trigger bar was also very simple. The problem came after the frame was completely reassembled and I went to put the slide back on and function test the gun. The slide for my Glock G43 will not install as it catches on the trigger bar striker safety "hump". I double checked everything without any resolution. Attempting to verify the problem (and allow for better photos to be taken for Apex Tactical), I removed the barrel, recoil spring, slide cover plate, striker, locking block and slide lock. I tried to reinstall the slide and it still hung up on the trigger bar striker safety hump. UGH!!! For final verification I removed the trigger assembly and (as expected) the slide would go fully onto the frame. I spoke with Apex Tactical customer service (Juana). I give Apex Tactical's Customer Service a good rating as they are were very quick to respond to this issue. I was also told that they have already received many phone calls about this problem. Apex sent me an email with questions to be answered and with photo requests of my G43 before I hung up the phone with Juana. I will post an update when I get a reply from Apex Tactical with their recommendation/solution.
