shoot shorts in lr barrel?

I have a model 107 Olympic ISU Military Pistol. Is there anything seriously wrong with mounting one of my extra 8" or 10" LR space barrels on it and shooting shorts in the chamber using the Olympic's magazines and slide?
Generally pump, and other action 22 rifles will let you interchange shorts, longs and long rifle ammo at will.

              Thanks John. I am sure every short shooter I ever had is on the newer side of 819,000.

            Hello Jack, I will need to get some guns out and look. I'm pretty sure they were still using 1 in 16 at the end of the 101 series. John Stimson
