I really like this sound, the base is beefy, powerful and Realistic and it's so clear -- no bad filters or any distortions of any kind, plus i love how you made it to be powerful yet at the same time clear and realistic. This is very hard to do, even for experts so i'm very impressed at how you did it. I think it's more powerful than Realistic but nevertheless, it's a great sound.

Despite being a great sound, it's nothing new and if this wasn't the first sound like this i'd actually call it spam because all you did was speed up the default Glock sound. But since you were lucky and you were the first to submit it first, i'll let it go. It also lacks echo, the default Glock sound never even had any echo so i don't think you can do anything to fix this other than using a reverb plugin for it.

Not much you can do to improve this though but i'd suggest adding more bass, amnplifying it for immersivity then some reverb. And equalizing it would never hurt to try too.

Overall it's a great sound but not a new idea and it's not really unique and you probably rushed on it but still i like it, good job.
