I'm a little unclear what you mean by your "sports shooter" (since bullseye target pistols are classed as "sports pistols"), but am going to assume that you don't intend to compete in bullseye shooting with it. In case I'm wrong, keep in mind that most (not all, just most) bullseye shooting in Canada is ISSF, and .45 is not allowed. Scoring is based on .38 in the centrefire portion.
I shoot both NRA and ISSF style bullseye, generally with my Hammerli SP-20, but my favourite gun is my Colt Series 70 Gold Cup National Match in .45. In NRA shooting in the States, .45 is required for the 2700 matches and so there's a big following down there for extremely accurate 1911's, since the precision targets are shot at 50 yards one-handed. Up here, not so much at all. If you think you might get into bullseye, keep calibre in mind.
