I took a full size medium grip frame ($39.95-free shipping) and cut it down to the compact size. This is almost the same proportions as the 1911 Commander to the government model.
full size medium grip
17 rd magazine
3/4" shorter slide and barrel
It's not quite finished; I need to do some slide matching contouring at the front of the frame and do a fill in at the front of the frame. I may shorten the frame just a bit more. Thought it'd be a good idea to shoot it before going any further.
Here's the surprise, well for me at least, the fs slide works too!!!
And just for reference a full-size slide on a full-size frame.
Well, now I have an excuse to go shooting.
