Narrative:
Was cleared for the visual approach for runway 23L on downwind. I turned toward the FAF as per company procedures; when it looked like I was going to have a 90 degree intercept I turned the aircraft to intercept the localizer just inside the FAF. Thinking that I was going to be high when I finally intercepted the GS; I used the vertical speed mode to start descending to 2200 ft at 200 FPM. When the GS indicator came in view; it showed the aircraft approximately 1.5 dots below the GS. First officer stated the fact that we were low on the GS; I then disconnected the autoplt and leveled off until we reached the GS. The aircraft was configured and on GS by 1000 ft AGL and we landed without incident. I should have flown another mi or two outside the FAF and given myself more room to maneuver for the localizer and GS intercept.

Title: AN ACR PILOT FLYING A VISUAL APCH WAS LOW ON GS BECAUSE OF A DESCENT DURING A TURN TO FINAL INSIDE THE FAF. A STABILIZED APCH WAS COMPLETED.
Narrative: WAS CLRED FOR THE VISUAL APCH FOR RWY 23L ON DOWNWIND. I TURNED TOWARD THE FAF AS PER COMPANY PROCS; WHEN IT LOOKED LIKE I WAS GOING TO HAVE A 90 DEG INTERCEPT I TURNED THE ACFT TO INTERCEPT THE LOC JUST INSIDE THE FAF. THINKING THAT I WAS GOING TO BE HIGH WHEN I FINALLY INTERCEPTED THE GS; I USED THE VERT SPD MODE TO START DSNDING TO 2200 FT AT 200 FPM. WHEN THE GS INDICATOR CAME IN VIEW; IT SHOWED THE ACFT APPROX 1.5 DOTS BELOW THE GS. FO STATED THE FACT THAT WE WERE LOW ON THE GS; I THEN DISCONNECTED THE AUTOPLT AND LEVELED OFF UNTIL WE REACHED THE GS. THE ACFT WAS CONFIGURED AND ON GS BY 1000 FT AGL AND WE LANDED WITHOUT INCIDENT. I SHOULD HAVE FLOWN ANOTHER MI OR TWO OUTSIDE THE FAF AND GIVEN MYSELF MORE ROOM TO MANEUVER FOR THE LOC AND GS INTERCEPT.
