Overview
Received the Pinty Buster .177 a few days ago.
All my pistols are in .177 since I am a target shooter.
It is accurate up to the 18 yards I tried with a dot sight.
If I had a better sight it would have been even more accurate.
I can say I really like it for the $230-$250 I paid for it.
Build
Build quality is really good, at least as good as the PP700 or PP750.
One thing the build I do not like too much is the synthetic (TPU ?) grip, but I can change that easily.
Magazines are good, but I need to gently push the pellets in (use a toothpick) since they don't just drop in.
It feels hefty, around 2.5 lbs, but is manageable with 2 hands.
It is heavier than the PP700/PP750 and slighly longer.
Trigger
The trigger may need more work.
After using only the 2 adjustment screws, I got it to under 3lb.
It is single stage and has almost no travel length , you pull, trigger barely moves and then it shoots.
The safety has a screw that needed to be tightened on mine.
Hammer spring
The hammer spring has about 3-3.5 turns from flush to max in.
The grip will stop it from going out of the receiver.
Stock hammer spring dimensions: OD: 8.5mm, Wire diameter: 1.25-1.3mm, Length: 43.7mm.
The stock hammer spring is way too strong.
With the stock spring I got a max of 850-860 FPS with Crosman Field Point 7.4 grains for all the hammer spring positions.
I replaced the hammer spring with a different one I made.
The new hammer spring was cut from a spring with a 8mm OD, 1.2mm wire.
WARNING: A spring with 9mm OD did not fit in the hammer hole.
I actually cut 2 of those springs, both shorter than the stock one.
One of the new hammer springs gives me a range of 420-720 FPS with the 7.4 grain pellets.
The other one 540-800 FPS with same pellets.
Shot string
With the stock spring I got about 850-860 FPS consitently for 20-30 shots (did not shoot much at this power).
With the lowest powered spring, I get 415-430 FPS cosistently for 120+ shots (got bored and stopped counting).
Perfect for target shooting up to 10 yards.
Noise
It comes with a 1/2-20 threaded barrel.
With the moderators I 3D print it become very quiet.
Some companies give you a permanently glued poorly performing moderator.
I am not buying the AIr Venturi Alpha because of that.
Conclusion
This and the PP700/PP750 are the best budget PCP pistols around.
Unfortunately the PP700/PP750 are not sold in the US.
The 250 bar fill pressure and larger air tank gives you way more shots than the PP700/PP750.
Lower price than what I paid for the PP700/PP750 5 years ago, including the thread adapter.
