I use a 1911 on duty, not a 2011 (yet). I’ve had two catastrophic (part breakage) failures of my Glock 34.3 I carry on duty when not with the 1911, extraction issues on my off duty 19.4, firing pin started to seize on a 34.5 I use for training. Countless mag related failures with worn/dirty OEM and Magpul mags in competition with my 34.3. Triggers/connector components wearing into a gritty mess on multiple guns. And so on. Point being, guns break, regardless of Glock or STI. Proper maintenance helps, and yes Glock’s CAN be more reliable out of the box, but I don’t see them as some perfect holy grail of reliability and shooting ability. Just another tool that’ll break like everything else.
My 1911 is getting some upgrades (no, I don’t have a second duplicate gun, I’m a broke dumbass and looking to correct that very soon) so I’m carrying my 34.3 again. With proper maintenance, and good mags I’m confident in the gun’s reliability, same as I am with a properly setup 1911, but I shoot the 1911 better.
