[Set] F1 Firearms BSF-19B - Black [EMG] + 34rd Green Gas Magazine for Combat Master, XTP, SHARK, SCORPION, F1 BSF [EMG]

I've acquired this pistol solely because of it's looks. It has an interesting design. To be honest I was really impressed by the it's overall build quality, the finishes are superb.
The first thing I've done to it out of the box was a good clean of it's internals and just the right amount and type of lube to make it cycle flawlessly. This is because the gun was really greasy, probably for storage on the shelf purposes.

I already got around 500 rounds through it, around 300 without the RMR and the rest with it. Thus my first impressions are really positive. For such a tiny platform, it's really accurate. I've used G&G 0.25G for all my shooting, this being what I generally use in my pistols. I was extremely impressed by the trigger, it's really crisp, tactile and "loud" so to speak. When dry firing you can really hear it both on the 1st press but also after you reset it.
The gun's frame is made out of metal, but surprisingly, it doesn't feel heavier than a regular Glock.

Now, on to the RMR shooting experience, GBB Pistols tend to be affected by their slide weight, and this pistol is no exception, even with 30 degrees Celsius outside, on regular gas, it tend to used slightly more gas, that wouldn't be a problem, but I've noticed that on rare occasions the slide didn't lock after the last round, so, my solution was easy, I've switched to a higher pressure gas to Nimrod Black, which solved the issue and also made the gun cycle faster with the RMR on top.

For now, the only issue I could find is the slight low tolerance between the slide and the frame. It has quite some play, not sure if it affects much of it's accuracy on short distances, and for long shots, I didn't test it because I tend to switch to pistol mainly as an emergency when the primary rouns out of ammo.

To conclude, after 500 rounds and more to come, the run runs and performs exceptionally well, and I really recommend getting one.
