Need & want ... are two different things entirely !
The Browning Citori " XS Special" , "XS Sporting" and "525 (type)Sporters"
all come in 32" ... if it's the "parallel target" type you seem to like, have a look at the XS Special with adjustable comb.
The 682 Gold E is a more convential "flat rib" sporter, as is ther XS Sporting and various 525's. Fewer & fewer "high rib" sporters out there these days.
32" barrels seemingly come into their own on the longer targets ... the only ones that seem to really need 32" barrels are those that don't already have them

!!
Gun fit, as I'm sure you know, is paramount to good Sporting scores, as is balance ( right at the hinge pin for most ) beyond which exposure to every imagineable type of target presentation & a pant load of practice. 2 " of extra barrel length, in and onto itself, won't make a lot of difference in your score. I'd far prefer to shoot a good fitting, well balanced 30" gun to one of 32" with all the bells & whistles which was not well-fitted and well-balanced !
But then again, IF you really want one .... ( just make sure it fits & is balanced properly, if not, you will not likely shoot it well ! )
