Ruger P89, .45 1911, both heavy guns.
Yeah...those are both some very weighty pistols. 1911 is my all time favorite for Winter carry (off the bike), but no way could I lug one around in a jersey pocket. Even my little Walther PPK/S was too heavy for riding with. The new compact and sub-compact polymer pistols are much better for CCW and riding...not that I'm in love with plastic pistols for anything else than their weigh savings. Similar to a carbon fiber frame I would think...not a lifetime investment, but a device with a purpose.
