I just had some fun and created this short little vfx shot using only Hitfilm (color grading too:)
It looks very good. I see you did attention to detail. I have only two remarks:
1. The fire coming out of the muzzle, you don't have to attach it to the movement of the gun. For example frame 57.
2. The smoke coming out of the gun on the last shot doesn't look natural.It should appear after the flash effect, not along with it, and be more diffused, over a larger area.
I would recommend using a CO2 or green gas gun with blowback. In this case the blowback is much more realistic. The wrist work on one hand and the slide back movement on the other.
Nice, well executed shots had me hooked the entire scene.
It looks real enough to my untrained eye. Certainly a safer way to film than using a gun with blanks.
p.s. It looks like you've disabled embedding. The video only plays directly on YouTube.
Looked good to me.
Looks good to me. Particular kudos on you added cast lighting. It's subtle, and often added cast lighting is way too bright.
Regarding @assensy 's notes. The smoke probably only needs to move one frame later. The size of the amoke didn't bother me, but consider using keyframe animation to scale the smoke up over a few frames. This would help give it a little more spread and diffusion.
If you don't have a gas blowback gun, you can animate the slide, although it's a bit of a pain. I won't go into it here.
This is an older Ae tutorial on animating gun slides, and it should basically translate into Hitfilm. It's going to be masking, duplicating of layers, and a little keyframe animation. Maybe a simple point track. With your shot it's harder because the camera and actor are both moving through a shifting background, which will make it harder to patch the BG around the slide.
Here's a clone stamp tutorial. Clone stamping might be the way to fill in your BG if you choose to animate the slide.
Thanks @Triem23! I'll check those out!
