1: Guns go 'click' as well.

2: That 1911 is comically oversized, scaled wrong.

That size of a 1911 is as large or possibly larger than a full size, 50 AE Desert Eagle.

... there are a few upscaled 1911 designs, blown up to use a 50 cal, marketed toward defending yourself against bears... but they usually have a longer barrel/extended compensator.

This thing in the image is just giving me 'babies first custom CS gun model' vibes, lol.

If the 1911 was scaled smaller, such that Sandler was doing good trigger discipline with his first finger knuckle about where the trigger guard is... that would be about the right scale for a typical .45 1911, or at least closer.
