9mm Fun
I started out trying to shoot a 9mm (wishing to do so , anyways) from my Loaded Parke'd 1911 and then after all the discussion I ended up buying another 1911. I was super lucky since I found an ad for an IMBEL 9mm M973. It was in mint condition and was about $ 400 CDN cheaper than a .45 Loaded Springer.
Now I have both calibers to play with and I did not need or have to modify a wonderfully shooting .45 at all.
By the way, this IMBEL is just fabulous. If you thought the Springfields that IMBEL are made really well, you should see this box stock M973. It's way better than any Springfield I've ever shot. Super well finished internals. I just swapped out the hammer (GI style), round MSH, GI grip safety, and GI safety for some high thumb shooting goodies.
Sorry to hijack this thread, but yes, instead of modifying your .45, just buy another M1911. Who knows if your .45 will shoot as well once you've tweaked it to shoot 9mm's.
Cheers,
