Assembling a Glock 43 Lower Frame

So after all the work I put into my Glock 43X, I had a bunch of parts left over that I didn't have much to do with. I decided to buy a Glock 43 lower frame for $80 and put all of my spare parts into it. Since the slide is the same as the 43X, I can switch the slides between the two lower frames, giving me more options for concealed carry.
