Today I remove the lawyer spring from the trigger of the Umarex Markpoint air pistol so we can see what affect, if any, it has on the accuracy on the pistol.

shootski

Before I do that I have a special test that was requested by reader shootski. He asked me, “Could you try shooting it unrested using your two hand extra finger technique before any modifications. PLEASE.You have an enviable pistol shooting track record so no chance of embarrassment; just the comparative FACTS.”

“I for one would be interested to see how much the dispersion increases in the hands of a good shooter. This is at best a PLINKER pistol in my opinion and most owners won’t shoot feral soda cans rested.”

Just a word, here. I shoot the pistol rested to eliminate myself from the equation. You want to know how accurate the airgun is—not how well I can shoot it.

Okay, he asked for a test with me shooting unsupported. I read that as standing and shooting offhand with no brace for my arms. I say arms, plural, because I have not yet removed the lawyer trigger spring and I still need to use two fingers to pull the trigger. It was an uncomfortable hold, to say the least!

I seldom shoot a handgun with two hands. I have forced my self to learn to do it over the years because so many people shoot that way now, and I will admit that with a gun that has a good trigger I can do pretty well. But the Markpoint trigger isn’t good as it comes, so this was extremely uncomfortable. I was shaking  like a leaf in a hurricane!

Best pellet

I selected the most accurate pellet from the test in Part 3. That was the Chinese Qiang Yuan Training pellet, but only by one-hundredth of an inch. The error in measurement is greater than that, so I could have used the H&N Finale Match Light pellets, as well.

Results

I shot low with all five shots. I had to measure the group with the target still attached to the pellet box trap. As best I can tell I put five pellets into a 3.611-inch/ 91.72mm group at 10 meters. I will say that the fixed open sights are ideal for shooting offhand!

Five Qiang Yuan Training pellets made a group measuring 3.611-inches/91.72mm between centers, when fired offhand from 10 meters.

I could hit a tin can at 10 meters most of the time shooting this way, but it isn’t pleasant. I shake like a leaf. And of course I would have to hold over the target to hit it.

Remove the lawyer trigger spring

I removed the 10 screws and the one pivot bolt that hold the plastic sides of the receiver together. Yes, the pivot bolt must come out, but you won’t cock the pistol when it’s apart, so it’s okay.

No one has mentioned this anywhere but there are two different screw sizes used to hold the Markpoint together. The three in front (the three closest to the muzzle) are thinner and longer. The other seven are slightly shorter, larger and are all the same size. I found this out during assembly after the spring was removed, and I’m trying to save you from doing the same.

There are three screws like the one on the left and seven like the one on the right. They look different in this closeup, but not as much when you see them in real life!

Spring removal

Fortunately, old BB is a pro. He doesn’t need to carefully remove the trigger spring. It just pops out as he examines the mechanism. Perhaps I’ll even find it someday. It’s probably turned into a sock somewhere inside my clothes dryer! That’s a word to the wise, guys. Be careful with that spring if you ever want to see it again!

The Markpoint action. The trigger spring has conveniently hopped out of the gun before this picture was taken.

Assembly

Assembly was the reverse of disassembly, except for the trigger spring popping out. 

Trigger pull

Is the trigger pull any better after that spring is removed? Yes, it is. It’s a one-hand trigger now. I do feel considerable creep in the pull, so perhaps some lubrication is in order. You readers would ask me to do it anyway, so I did. I used SLIP 2000 EWL that is proving to be the best slippery lubricant I’ve ever seen.

After the trigger spring removal but before lubrication the trigger pull measured 6 pounds 4 ounces. There was one spot of hesitation (creep) in the trigger as it was pulled.

I lubed all pivot points and contact point with SLIP 2000. Then, after assembly, I shot the pistol 8 times to work the lube in.

After lubrication the trigger pull measured 6 pounds 4 ounces, so there was no change. The hesitation in the pull might have gotten better, but it’s difficult to say. In my opinion, lubing the Markpoint trigger mechanism does nothing. (I’ll come back to that in the next report.)

Summary

This report is getting long, so I will do the next accuracy test on Monday. Stay tuned.
