Umarex P-08 BB pistol
The new Umarex P-08 BB pistol is a stunning copy of the firearm.

Time to learn gun terms
Before I start today’s report, I must make a comment. It deals directly with the subject air pistol, but it also deals with many others. The trigger on the Walther P-08 BB pistol is double-action. It is therefore harder to pull than a single-action trigger. I have read several overseas reports of this gun that complain about the “hard trigger pull.” The trigger-pull of this pistol is not hard — it’s double-action, which means that your trigger finger is first cocking either a striker or a hammer before bringing it to the point that the sear releases it to fire the gun.

My own brother-in-law shocked me this past Christmas when I took him to the range and let him fire my Makarov pistol. I told him that it’s a double-action and single-action handgun, so expect the first shot to have a heavier trigger pull. He did and of course the gun’s trigger-pull was heavy. Then, it fired again before he was ready and he remarked, “Wow, this trigger sure gets lighter after the first shot!”

Well, of course it does! It shifts from being double-action to single action, which would be the reason the trigger-pull goes from 10 lbs. down to 3 lbs. On the second and all subsequent shots, you don’t have to pull the hammer back with your finger — the slide does it for you. But it still shocked him.

To me, not understanding this is as absurd as complaining that you can’t find the clutch pedal in a car that has an automatic transmission. But people don’t do that, do they? They “get” that an automatic transmission does away with the need for a clutch pedal.

But new shooters and some that aren’t so new are still not understanding the meaning of a double-action trigger-pull. So, here’s a photo that I’d like you to internalize (if this is something you’re having difficulty understanding).

Umarex P-08 BB pistol double action trigger pull
This is what you are doing every time you pull a double-action trigger — whether you can see it or not.

Back to the test
Okay — rant is over. Today is velocity day, when we test the P-08 pistol with Umarex Precision steel BBs. I noticed when I pierced the CO2 cartridge that the gas leaked more than usual. It caught me by surprise, and I had to tighten the piercing screw several more turns before the face seal finally stopped the gas flow. And, yes, I did have a drop of Crosman Pellgunoil on the tip of the cartridge.

Then, it was a simple matter of loading 21 BBs into the stick magazine, and the gun was ready for testing. You may remember that the advertised velocity of this pistol is 410 f.p.s., so let’s see what it really does.

The first 10 shots averaged 384 f.p.s. They ranged from a low of 378 to a high of 393 f.p.s. The pistol started slow and sped up as the string was shot. I rested a minimum of 10 seconds between all shots.

The second 11 shots (21 in the mag) averaged 394 f.p.s. The low was 391 and the high was 399 f.p.s. The slowest shot in this string was faster than the average of the first 10 shots. The gun seems to be breaking in.

Next, I shot 10 blanks, just to use up some gas because I suspected the next magazine would be all there was. I was wrong about that.

Shots 32 to 42 averaged 382 f.p.s. with a low of 377 and a high of 385 f.p.s. The pistol seems to be settling down.

Shots 43 to 52 averaged 386 f.p.s. The low was 382 and the high was 398 f.p.s. The gun had more shots remaining after this second magazine.

Now, I decided to just shoot the entire 21-shot magazine and record the average. Shots 53 to 74 averaged 381 f.p.s. The low was 358 f.p.s., and it occurred at the start of the string. The high was 388, which occurred at shot 71. Go figure!

The next magazine started at shot 75 and ended at shot 96. The average was 371 f.p.s. At shot 88, the velocity started to fall rapidly. The cartridge was out of liquid and was just putting out residual gas pressure at this point.

How many shots?
I believe this gun will be good for at least 4 full magazines before its time to replace the cartridge. If you don’t replace it then, you could get a BB stuck in the barrel when the pressure drops too low.

I do believe this gun needs to break in a little, and you can expect to see velocities climb a little after several hundred shots have passed through.

Trigger-pull
I measured the weight of the trigger-pull for you. It’s a light 9 lbs., 2 oz. to 9 lbs., 5 oz. Compared to a Colt or Ruger revolver, that’s very light. There’s a definite stack at the end of the pull; so once you learn this trigger, it should be very easy to control.

Opinions thus far
I still like this pistol. There were no surprises in this test except for the greater number of shots. I’d estimated about 60 good shots and there are really over 84. Watch that piercing screw, as this one seems to need more movement than many CO2 guns on the market. I might have lost another 10 shots just by losing the gas in the beginning.

Can’t wait for the accuracy test!
