I did find some other Forums with pics and stories...It appears the conversion process evolved over time...There were full-length conversions as well...
John, it's not quite that easy to put the Commander slide/barrel on a 5" frame and expect it to work...I've done it but it does require a bit of machining to the frame...Otherwise the Commander slide won't travel rearward far enough...In the old days (before Commanders), they just cut 3/4" off the slide/barrel & re-cut the bushing slot...
I probably could do the conversion, I have the patent number now...And it looks do-able...Maybe someday...
