I own two Beretta 92FS pistols (full size) and three Glock 19 GEN3 pistols (soon to own a fourth - had the high bid on one this morning). I don't think I have any other firearms for which I have more than one of the exact same model. I come close with two shotguns, but close only counts in horseshoes and nuclear weapons. Those other two are both Remington 870 Express shotguns but one has a 3" chamber, the other has a 2.75" chamber; so technically, they are not the same exact model. Same thing more or less as with the 870s for a couple of Ruger Mark II pistols I own but they have different barrel lengths.
