Rick,RickB said:The plug came with it, yes? The "problem" with the FLGR is that you must turn the bushing with the gun in battery. If you have a nice, tight bushing fit, you are wearing it out every time you strip the gun, as the barrel is not concentric with bushing when in battery. You can turn the bushing while the slide is still off the gun, as then the barrel and the guide rod can move around a bit, and you're not putting excessive wear on anything, but I don't much like handling the greasy/oily top end when it's off the frame.
Push the guide rod in through the rear of the slide, push the recoil spring in through the front, put the top end on the frame, insert the slide stop, compress the recoil spring and plug until flush with the end of the slide, then rotate the bushing to lock the plug in place. Once you have the rod and spring in the slide, the assembly is the same as for a short rod, except the slide must be all the way forward in order to turn the bushing.
