on some rare occurence, because of this "hard trigger push" the hammer would go into half decock mode.
When I tighten the screw on the blowback housing, the slide would stuck. So What I did was untighten the screw until a certain point where its not tight enough and the cycling would go smoothly. Is this OK to do?
My gun was chronoed 2276-280 FPS using guarder gas and .2 bb. Is this
normal?
Gas usage was quite high, I could only shoot 20 bbs using hi capa 4.3 mag
Thats all guys, Any help would be appreciated. Thanks

2276fps w/0.20g bbs is NOT normal...
just kidding around.
Torquing the the blowback unit out of alignment is "normal" I suppose...because it's happened on two of my pistols as well. The harder I tighten, the stickier the slide is. Both are SD slides. The front two rails of the blow back housing are rubbing the tops of the rear frame/rails. Don't even bother troubleshooting gas usage until that is sorted out. On mine...the housing was being tilted "down" at the front (i.e. the rear of the housing was clear from contacting the frame, but the front wasn't)
I did the following to get the slide moving smoothly.
- i used a set of honing stones to sand down the areas of the blow back housing that were contacting the frame. I used a sharpie marker to "blacken" the areas so the spots that were wearing would show up silver
- i inspected the rear area of the frame to see what was rubbing and lightly leveled those areas as well
I can now properly tighten up the screw and the action is pretty slick. A little grease on the rails and parts that ride on each other helps.
It took more than a few assemblies...I didn't want to take off any more material than I absolutely had to and I was using pretty fine honing stones. It's obviously a permanent modification...but that pistol is staying as is...so I'm not concerned with that.
So far as the trigger pull goes...I'd also examine the clearances around the opening for the trigger and trigger bar/loop to ensure that it's not binding or hanging up on the frame.
Best of luck.
