My interpretation of the OP is that he is comparing the Buckmark, and the 1911-22. Both 22 rimfire handguns so the 1911 would have no HD advantage. The Browning rimfire version of the 1911 is about 3/4 size compared to a centerfire 1911. Either would be a good plinker, practice firearm, but the Buckmark might be a little more accurate.
