Project m21 is now complete, now that all parts have been installed, internal and external. All that is left to do is test it, though that will have to wait until my local site re-opens. In theory, it should shoot really well...
Also, 1911 is complete too, but that literally took me about 10 mins to do total. Put suppressors on everything!
