Dang kids, ya ain't never satisfied, always bored. Are we there yet Dad? I luv ya Crazy, yer a inspiration but Holy Geez, ya just can't go out an play with whatcha got, ya'll need somethin' new alla time. Well, I'll give ya somethin' to do - take one of yer 1911A1s and dedicate it to a conversion pistol. You can get 38 Super slides and barrels from SARCO and, internals from Numrich/Gun Parts Corp but you need to be aware that some parts come oversized or may need working or polishing, such as the firing pin stop plate or the extractor hole in the slide or the link pin hole in the barrel. But, once you get that working (just ran a box of ammo through my 38 Super conversion) then you can see if it works with the 9mm barrel conversion or the 7.62x25mm barrel conversion. I believe that once you convert to 38 Susper/9mm you can just switch slides to the 10mm/40 S&W but you have to change the ejector out to go back to 45.
I just completed the conversion on my Springfield 1911 frame and I'm having a ball, except for finding empty brass. Honest to Goodness, I think there is a Legion of Lost Brass floatin' around somewhere that recruits empty shell cases right off the firing range when you're not looking. Yesterday I am in my back yard testing function and reliability of the 38 Super conversion and having a good time with my groups and then I have to go lookin' fer the empties. Now, I know how many I shoot as there are that many empty holes in the boxes and all the empties landed in a relatively small space, possibly 12 foot square and I had cut the grasses there the previous day but could I find all my empties - naw, not a chance; maybe a dozen lost.
I tried the plastic sheet and then bedsheet trick but to no avail - it was too windy and if I had turned to try and keep the brass landing on the sheet I prolly woulda shot my neighbor. Hmmmm.........
