My Top 3 in the 45 Auto arena, though there are many great platforms outside of these:
HK45 Compact Tactical: my favorite handgun on the market (regardless of cartridge) and the single handgun platform I'm most invested in.
DW Specialist: every collection needs a 1911 in 45 Auto (and 10mm... and 9mm... maybe even 38 Super ).
Ruger New Vaquero: allows me to shoot 45 Colt for fun, and gives me a platform that eats some of the oddball 45 Auto loads that I hand-roll that don't get along with autoloaders.
