This report covers:

  • Correction
  • Sig wonders why we want to disassemble the gun
  • The test
  • Sig Match Ballistic Alloy
  • Rifled barrel
  • Magazine gas loss
  • Air Arms Falcon pellets
  • Crux Ballistic Alloy
  • Blowback
  • Trigger pull
  • Daisy BBs
  • Smart Shot a no go
  • Beeman Perfect Rounds
  • Shot count
  • Discussion
  • Summary

Today we look at the velocity of the Sig P320 M17 pellet pistol. But there will be more to this test than just three pellets. Because readers wondered if it could also shoot BBs and I learned that it can, I will test them, as well. As long as I’m testing BBs, I will test lead balls of differing sizes, because when we get to the accuracy test I’ll want to test them as well.

Correction

I told you in the last part that the magazine cap has to be removed to insert a CO2 cartridge. That was incorrect. Just remove the mag from the gun and insert the cartridge by following the directions in the manual. Leave the cap alone. read more

This report covers:

  • The test
  • The trigger
  • Sight-in
  • RWS R10 Match Pistol pellets
  • Sig Match Ballistic Alloy pellets
  • Strange sound
  • RWS Meisterkugeln
  • H&N Finale Match Light
  • Qiang Yuan pellet
  • Summary

Today I shoot the Air Venturi V10 Match pistol for accuracy. Let’s get started.

The test

I shot from 10 meters off a sandbag rest that has no influence over this pistol because it is a pneumatic. I shot 5-shot groups because a target gun usually puts them so close together that 10 are hard to see.

The trigger

In Part 3 I tuned and adjusted the trigger on this pistol and I nailed it! This is the nicest Gamo Compact (the base gun) trigger I have ever used and I think my trick with relieving the wood around the adjustment screw is the difference. I could shoot a trigger like this in competition! read more

This report covers:

  • Trigger adjustment
  • Whiskey3 4-12X44 scope
  • Today’s test
  • Velocity with the lead Crux Pb
  • JSB Exact Jumbo
  • JSB Exact Jumbo Heavy
  • How fast will she go?
  • Easy cocking!
  • Barrel loose when cocked
  • Trigger pull
  • First stage?
  • Summary

Today we will find out about the velocity of the .22-caliber Sig ASP20 breakbarrel rifle that I’m testing. Before we get into that, though, I have a couple things to address.

Trigger adjustment

First, reader Siraniko asked this:

“You will have to show us a picture how the trigger is adjusted while in the gun. The only picture I could find of how to adjust the trigger showed it while separated from the gun (https://www.pyramydair.com/blog/2018/08/my-day-at-sig-sauer-part-2/).”

That’s a good question. He asked because I showed the bent Phillips screwdriver that’s used to adjust the trigger pull weight. So let’s discuss the trigger adjustments now. read more

  • Summary

Best-laid schemes…

…o’ mice an’ men gang aft agley! The poet, Robert Burns, was right when he said that. I told you that I was going to show you how to lighten the trigger of the Air Venturi V10 Match pistol today, and I am. But in the past this has always been a simple 15-minute job. It should take me maybe 30 minutes with pictures. I had planned to do the accuracy test today, after finishing with the trigger. Nope! Instead I struggled for some time, and in the struggle I learned something valuable that I will now pass on to all of you.

Straightforward

The job I’m going to show you is straightforward. It should be easy for everybody, as long as you don’t stray past where I’m taking you. In Part 2 we left the trigger at between 2 lbs. 2 oz. and 2 lbs. 9 oz. pull. A 10 meter pistol trigger can be as light as 500 grams, which is 17.64 oz. or 1 lb. 1.64 oz. So, where we left the trigger was more than one pound too heavy. read more

  • Back to the M17 pellet pistol
  • Operation

  • Summary

To all our American readers I want to wish a very happy Thanksgiving. Now, on to today’s report.

On January 19, 2017 it was announced that the U.S. Army had selected the Sig Sauer P320 pistol for their new Modular Handgun System. The full-sized gun is called the M17 and the carry-sized weapon is the M18. The rest of the U.S. armed forces also have or will have this sidearm. The nominal caliber for the U.S. military is the 9X19mm pistol cartridge that is best-known as the 9mm Luger.

M17 differences

The M17 is not just a P320 by a different name. The Army specified certain performance requirements for their pistol and they require Sig to maintain a strict separation in their plants between Army contract guns and similar civilian guns. This not only covers the finished guns but also all parts. read more

    The Johnson Indoor Target Gun is a catapult BB gun that was made in the late 1940s for youth target practice.

Part 1

A history of airguns

This report covers:

  • Operation
  • Cocking
  • Trigger
  • Serendipity
  • Pat is not pending
  • Adjustable sights
  • Repeater
  • Summary

I was going to write about something else today, but the response to Friday’s report convinced me to stick with the Johnson. Several of you said that you enjoyed the detailed photos. Today I will tell you about how the gun is constructed and how it operates, plus some special features. Grab your coffee cup and let’s go!

Operation

The Johnson gun is a catapult gun, and in Part one I showed you the broken surgical tubing in my new gun. Now, take a look at a gun with tubing in working condition.

Johnson rubber working
This is how the rubber is supposed to look when it’s properly installed. The ends of this surgical tubing are held together with small cable ties. We are looking at the inside of the top cover of the gun. read more

Air Venturi V10 Match pistol: Part 1

This report covers:

  • Why test the V10?
  • Description
  • Effort
  • Accuracy
  • Grip
  • Trigger
  • Dry fire
  • Sights
  • Construction
  • Left hand grips available
  • Summary

I had planned to start the accuracy test of the Air Venturi Seneca Aspen today, but I ran into too many issues while attempting to mount the scope. II will tell you everything that happened when that report runs.

So today a new airgun that was on my list was moved up. It’s the Air Venturi Match pistol. It’s a single stroke pneumatic that’s based on the Gamo Compact that I have tested in the past. But why test a target pistol at all?

Why test the V10?

Glad you asked. A couple years ago the Russian IZH 46M stopped coming into the U.S. and many airgunners regarded that as a major loss. Ten meter target pistols are on very few airgunners’ short lists, but whenever something is no longer available people do take notice. Most shooters consider a target pistol to be an expensive plinker with a good trigger. read more
