A design change lengthening the elastic gussetting was made because of this and the best fitting leather swivel holster (OEM) is ACC-08582-001. Again, the 72XX one will fit but it is very tight.
For the 7520 model, look for items designed for the 7250/7290 models. Profile differentials are virtually the same.
The design change you're talking about is also a style change (more squared)... The Acc-05150-001 has proven to be a very versatile case and does fit the 7290 as NJ points out. the very very tight you mention only lasts about 2 weeks - would you agree NJ? The 08582, when it gets into distribution will replace the 05150 and again be the generic 62xx/72xx series case.
Let me add that all of these leather cases from RIM require a break-in period to get the leather portion to "glove" the device. These cases rely on surface tension between the leather and your device to hold them.
There is a specific 6510/7510/7520 solution now... RAC5524/ACC-05505-024.
