Yeah it is cool, I think I've admitted this here but my two favorite platforms are 1911's and Glocks, not to many years back I bought probably too many Glock 22's and 35's, LE trade ins, 22's around 300, 35's little more, I'd do the same, convert to 9mm, as I mentioned above with the swapping around accidentally put a 9 in a 40 barrel, had swapped it back to 40 and forgot Had to punch swollen brass out but great way to have 2 calibers in one
