Narrative:

We were operating from frg; as a crew of two. I was the pilot not flying; in the right seat handling checklist duties and communications. I copied our instrument clearance and ATIS and briefed the pilot flying in the left seat. We were cleared to taxi frg to runway 19. Both of us were unfamiliar with frg. Ground control asked if we could accept an intersection departure from golf 4; which we declined and requested full length. Ground control cleared us across runway 19 with a right turn on bravo taxiway full length. We turned on bravo and taxied to the intersection of taxiway bravo and mike; and held at the 19-approach hold-short line. We called tower; who said that full length from mike was not available and to make a hard right turn back onto bravo. I replied that we could make the turn. I had seen pavement to the right and a clear path back to taxiway bravo. At no point would we be off the pavement; but it required taxiing between two blue taxiway lights. I believed ground control intended us to do this; as taxiway mike was narrow and it would have been impossible to make a hard right turn and remain on this taxiway. Also there was no way to accomplish this turn without crossing the 19 hold-short line on taxiway bravo. We continued; reversed direction at the intersection of taxiways bravo and charlie; and departed uneventfully.reviewing this event; I find a disparity between the NOAA and jeppesen airport taxi diagrams. The former shows pavement from taxiway mike to runway 19 and the latter does not. The pilot flying and I looked at the diagram on the aircraft's multifunction display and I believe it showed the former. I suspect the primary cause of this incursion was my misunderstanding the taxi instructions. The ground controller may have assumed we were familiar with the airport and I did not ask enough questions. The fact that taxiway mike has a 19-approach hold-short line (visible on google earth) can lure you down that taxiway; instead of bravo. I believe this hold-short line is misleading as it implies a direct path to a runway 19 departure. Also I wonder if this area should be labeled as a hot spot on the airport diagram.

Title: A corporate jet flight crew reported the FRG Jeppesen and NOAA charts depict the FRG Runway 19 approach end overrun differently. NOAA correctly depicts the overrun on either side of Taxiway M.
