Para-Ordnance, the originator of the first high capacity .45 ACP with its P13.45 frame kit, has developed a double action P14.45 [14+1] in their LDS [light double action] design. It has all the strengths of the original M1911 plus the double action mode for firing the first shot.
Personally, the DA option is a bit over rated. The first shot trigger DA pull is long and heavy, while second and subsequent shots are single action and light in comparison. This requires much practice to get a first round hit because of the differences in trigger pulls. The double action only [DAO] is the absolute worst of all actions because it ALWATS has long and heavy pull that does nothing for accuracy.
With a M1911 style pistol, the fastest and most accurate way us from Condition One [cocked and locked] and the trigger pulls are consistent from start to finish. Glocks are the same in this regard, though they have no thumb safety to manipulate.
The 1911 has more parts then a Glock thus more complicated.
I owned and shot both taken both apart and put them back together.
1911 is a more complicated design.
Link less vs linked, barrel bushing vs no barrel bushing and could on.
