Hello, I am starting on my first Glock 1911 build. I am focusing on gen 3. I have a Gen3 parts kit and a G19.2-75 3d lower. These are obviously not compatible. Are are they? This is my first build and I got the G19.2-75 files off of Github I am test fitting and there are mismatches by a tiny bit. At this point I have the magazine catch installed and works but the spring mechanism in the G2 lower doesnt match any of the Gen3 parts inventory. The image is what I am basing for instructions and this one might be wrong. Naturally I am trying to save money so I search for what is labeled as compatible. There seems to be a greater mismatch in what I am trying to achieve. Any further guidance would be appreciated. There is no Github link in the zip I downloaded it as a torrent from guncadindex.

Any G19.3 3d file recommendation is also accepted.
