New SPA Artemis PP750
- Thread starter RJGTA
- Start date
Trimming/replacing the spring reduced force, but didn't bring a light consistent break.
The trigger grub screw that adjusts the final stage break has a sharp point and was digging into the sear blade scarring it. Rounding and polishing that point, wet sanding and polishing the sear and sear blade where it contacts the trigger set screw really smoothed things out.
Also shimming the trigger and sear pivots took out some wobble that was causing the break point to change.

Thane, thanks for the information, the screw on the trigger blade to adjust the final stage is the one closest to the muzzle. I was able to achieve a light predictable break. A fun little plinker for sure!!

PP750 is a lot of fun to shoot and tinker with!
Did a bit of shooting at 25 yards settling on the JSB 8.4 gr pellets at 760 FPS making sub 3/8" five shot groups (even a few 1/4" groups). Huma LDC assisted in groupings as well as swallowing up most of the report, with red LED for some night-work.

Thanks,
I machined some aluminum rod on a lathe, 1/2-20 for LDC and 20-1.0mm for the barrel shroud matching taper to keep OEM baffles in compression. Single chucking for all cuts to keep it concentric.

So far the PP750 is more compact. Also the magazine is more compact than the Marauder Pistol mag. Out of the box in 177 it is quieter. The single shot tray is well designed. Just some initial impressions.
Not sure why they swapped it from left side clocking to right.
Would've preferred left cocking as originally designed.

Shooting off hand with the open sights I was more accurate with it as a pistol than with the stock extended. Very comfortable shooter as a pistola. Nice!
Stock extended is very stable. I don't like how the scope rail slides so freely.

That's a great pair of pistols!
The front rail should be removed if not in use, otherwise it grips down on the shroud in a firm fashion with a scope ring attached. Better than I expected.
Your PP750 has is bright metal behind the fill port cap that mine does not. Is this a mod, or did it ship this way?

Thanks. I just took off the front rail. Pretty slick idea actually. I just put my venom red dot on and will now see how she shoots.
My silver fill port is oem. I noticed you may have a Gen 2 lol. Who knows?i will chrony this little pistola and see what she is putting out. Some more pics.
Anyone else have their barrel off to the right sort of uncentered? Just curious....

My barrel does not have that spanner flat.
Maybe a .22 thing, spanner flat and alum fill port cap. .177 Black no flat...
Need more PP750 shooters, testing the waters... so far mine has been a lot of fun, handles were a bit of bling project.

Wow this is really just wow. I want it, yes I do. It's like an PCP PDW. lol
It'll be very handy when camping or during hunting season for small game because it's so compact and light compared to your full blown pcp rifles. I bet it costs close to $1000 tho.

Really sorry for the wait on the PP750, bummer this virus slowed things down. Makes a guy anxious to get them seeing all these great posts on them!

Nothing you can do Wes! I'll subtly try to avoid this thread until they come haha. I'm sure we all have other guns to enjoy in the interim.

Doing a little tuning this morning and thus far the PP750 been easier to work on than I was expecting.
1st off, I took a couple dB sound tests and it was 80 dB with no ldc and 69 dB with a donnyfl Tanto ldc. BTW, I found out the Gauntlet adapter through donnyfl works perfectly fine on it. I know some were wondering if it works with baffle spacing etc, so I took a gamble to confirm. Confirmed.
Hammer spring adjustment was easily accessible at the rear. A little surprised by the handle built around it. It limits how far you can back it out somewhat.
A really slick surprise was the magnets on the single shot tray and magazine and the magnetic function while placing the sst in.
So far at 11 yards with my 177 it has been stacking in 1 hole.
I am lightning up the triggers 2nd stage which came a little heavy imo.
So far.... I have to say the PP750 is the best indoor plinker I've owned and shot to date.
It is very comparable to when I had my Ataman AP16. (very very similar in features - only the AP16 was 3 times as much 2 times as loud it seemed and didn't have the awesome collapsible and fully adjustable butt stock of the pp750)
Off hand it is very very nice to shoot as a pistol.
Hope we can all start getting out and shooting these soon so the real tuning masters can chime in. This has been my short experience thus far.

I don't plan to shoot my pp750 passed 50 yards but If any are interested what the 22 cal does at 50....
Here you go.
Taken from the Urdu spoken pp750 review below. (also, if anyone can figure out what the differences are if any between the pp750 with a silver fill port VS the black ones like the one used in the video please let us know...)

I got one of Donny's Gauntlet adapters after reading a post that it would fit. Screws in fine, but I put a thick o-ring behind it as I noticed it wasn't quite deep enough to be flush with the baffle spacers. Just a little bit of tension as I tightened down the adapter. I agree the PP750 is not very loud stock, but with a Tatsu on it's very quiet.

That is some nice shooting!
I haven't had the chance to take mine past 25yds, but at that distance 1/4" groups is nice.
