Not a real real useful comparison. Glocks are a different type of sidearm. They are great Kodak guns, just point and shoot. Glock has amazing quality and reliability for the Price, but they are not for those who shoot 'Bullseye Competition' or +P+ ammo as their barrels do not have the strength (no Buffalo Bore Ammo for them).
The 1911s are not for those new to sidearms. Proficiency takes much work and practice. Also, manual safeties are never to be considered a bad thing.
I remember being issued my first ("plastic") Duty Glock, it wasn't a 'pretty thing' for sure, however, Glocks proved their inherent advantage of Point & Shoot reliably in LE.
There were NDs almost daily with Glocks in the U.S., when they became the choice of LE in the early 90s (much due to deep discounts).
Due to the emerging Crack/Meth epidemic, which caught U.S. LE agencies off guard, it was quickly learned LEOs were severly "Out-gunned"... the Cartels had an endless supply of semi & FA weapons while LEOs had revolvers & shotguns.... IT WAS A MESS!!
The Glock was the first Semi-auto sidearm with an increased capacity considered reliable/accurate/versatile/affordable/easy maint/easy conversion training/ and a remarkable 5.5 lb trigger + very affordable.
The early S&W 1st Gens were available to us, but they still had issues. Glocks were the first to offer the 'whole package' at a great price, the Sigs were their best competitor, but were more expensive with too many parts.
During my 40 year career in LE, I was issued many different Glocks, they were lightweight & extremely reliable and the beat my S&W 586 Revolver, so I loved Glocks for many years.
Once, I was transitioned to a G21 and even with my XXL (but thick) hands, that fat grip never really worked for me. (The better S&W M&P .45 was still in the future.)
Now, Glocks have endless competition..., And I did get the manageable S&W M&P .45acp 4.2 in bbl as I'm a 45 guy at heart.
I have always had 1911s in .45acp, but they are not the best choice for a Duty sidearm.
Being retired, my favorite carry is my Colt Defender .45acp at less than 0.99 inch wide and 22 ozs (my maximum allowances for any carry sidearms, nowdays) + the belt-clip ($20) requires no holster and keeps it "thin".
Glocks are not the 'BEST' sidearm out there, but for those who are comfortable carrying a sidearm over 0.99 inches wide, and want a true "Kodak", they are a fantastic value for all you get. I think their best attribute is the trigger, once you are trained to "bump" the 5.5 lb trigger, it can fire near as fast as a full auto.
(I once got DQ'd during a re-qual for 'bumping' a full mag from a Glock) Could never do it with any other make. (??)
