Range report and slow-mo video!
*spoiler* I quite enjoy mine, no buyers remorse this time.
Re-reading what I wrote before posting, it looks like a pretty negative take, but please keep in mind that every little aspect I DIDN'T mention was skipped over because it worked perfectly.
First things first, here's the video. As you will see, this thing is quite small and snappy. You can slow down the video even more by hitting the settings cog in the bottom right of the player.
This is with a moderately tight grip, no conscious effort to get back on target quickly.
Yep those are full power loads, nope I don't recommend them. Shot my first mag with leather gloves, a thick jacket, and face covered to avoid getting Kentucky Ballistics'd.
Hornady Custom 10mm 180gr. XTP HP, 1275 fps, 650 ft.lbs.
As others have commented, the recoil spring is much weaker than expected. I personally wouldn't fire real 10mm loads without a buffer, but good news regarding that:
Found that a *thin* CZ Shadow recoil buffer can be cut to fit the guide rod, close enough hole diameter, but needs to be cut around the perimeter to fit within the dust cover. Forgive my ugly, rushed hack job of that part... The pic below is how it looked after 20rds of the above full-power, and 20rds of (mild) Sellier & Bellot. That alone should give you a pretty good idea of how hard that slide is slamming back...
You'll also notice the internal finish on the slide rails is very rough. I'm actually going to keep this as a practical positive as anything slowing that slide down can't hurt.
No failure to feeds or fire using flat tip or hollow point bullets. Full-power loads ejected brass ~9 meters at 150 degrees rightwards from point of aim. Mild loads were ejected ~7 meters at around 120 degrees.
No signs of case-bulging in either load, seems to be staying locked tight long enough.
Ejection was indoobitably quite violent, see the pic below showing the extractor-marks left on the rims.**Dents were probably caused by the shorter stroke length due to the buffer, no confirmation on that**
Initial impression has me thinking alu cased ammo might be a best bet. That ejector is working overtime, so plan on damaging brass rims or *possibly* sending your extractor claw to snap-city if using steel case. That last part is just speculation, I'm no gunsmith.
That's all I got for ya, happy tootin'
