OH, AND ME PERSONALY I AM A BIG JUNKIE FOR THE SQUARE TRIGGERGUARDS. I HAVE BOTH, BUT I PREFFER BY A LOT THE SQ.TR. I KINDA SEE THE ROUNDED AS IF IT WAS "COST NEUTERED". HOWEVER, ONE HAS MORE CHOICES IN HOLSTERS WITH THE RND TRIGERRGUARD THAN THE SQ. FOR YEARS I HAVE USED A LEATHER BIANCHI S3 IWB FOR A BERETTA F92, AND HAS WORKED FINE. KEEP IN MIND, LEATHER CAN BE PLIABLE, AND A HOLSTER THAT FITS A SIMILAR SIZE GUN, MAY BE MADE TO FIT.
