Well mine arrived, and out of the box it was utter rubbish. I had the same issue with BBs hooking to the left. It also wouldn’t get though a mag without venting gas and the mag dropped out every other shot.
Taking apart the hop and putting it back together seemed to have fixed the hooking to the left issue (there was also way too much hop out of the box, it was over hopping .3g BBs) The mag catch screw was loose and tightening that seems to have fixed the random mag drops. A spray of silicone into the BBU seems to have improved the gas efficiency so it will at least finish a mag. (I also expect this to get better with more use as the piston head swells to a better seal).
Is it the best airsoft pistol I have ever had, no it’s a long long way short. Even a bog standard WE Glock will out perform it in every way, however I can’t help but like it, because it is a skirmishable MK3 hi-power and it feels just right. I even like the trigger as it really does feel like a real HP (which is the first RS pistol I learned to shoot with) it has the same slightly long and ‘grindy’ take up which releases the mag safety and then a break like a glass rod.
I don’t think it is fair to crono it or test accuracy until it’s broken in a bit, but I expect both to be no more than ok, but fine for a skirmish back-up, that will go awesomely with my MP5 GBBR for that full SAS vibe.
As noted above The hop is beyond primitive, so the only replacements are going to be OEM WE Parts. The brass grub screw that applies the hop is also comically tiny, I can see that working its way lose and disappearing into thin air at a skirmish so once the hop is set right I’ll use a pin to dab a tiny blob of thread lock into the edge of the tread in the hope that it will work it’s way down a bit and it is enough to stop it vanishing.
