P226 vs NP22 the maths show down.

[NavyCuda]

The winner: TIE!

Both the P226 and the NP22 are chambered in the same caliber, 9x19mm. Firing both pistols through the same chronograph, with the same ammunition these are the results:

Norinco NP22:

Sig Sauer Germany P226:

It is my opinion that the sample groups are too small to really make an opinion but it was very interesting to see that both pistols using the same ammunition netted the same average velocity and force.

Another interesting thing, is that the 9mm plinking ammo was ~2 ft/lbs more powerful than our plinking .45 ACP(avg. 767ft/sec, 300.4ft/lbs Fired from Sig 1911)

As far as accuracy is concerned I did not collect my targets as I was shooting for velocity but I will say that the P226 did group noticeably tighter than the NP22. I have no evidence to back up this claim but the next range visit will be more thought out.

Wouldn't the velocity be a function of the ammunition, not the gun? Shouldn't the same ammo fly at the same velocity regardless of the gun?

I have an NP22 and really enjoy shooting it. I'd really like to see an accuracy comparison between the two guns (especially since you've now shown that velocity is constant).

- Thank you for the post. It is nice to see something tangible towards the properties of the NP22 vrs a SIG rather than hearing "Chinese pistols suck" by some bitter no-it-all.

Great info. Thanks

Well I think about it this way, the NP22 must be a damn near identical match to the P226 to produce such close results. The barrel, rifling, timing, weight of the slide, etc, everything must be very close to the P226.

Velocity is based on a number of variables, projectile weight, charge weight, barrel length, barrel twist and probably other factors I don't know of. I'm too inexperienced with reloading to be an accurate point of information, but mechanically speaking the two must be very close.

Actually looking at the information some more, the P226 had a greater span in projectile speeds, and in other series the NP22 was edging out the P226 for velocity and consistency. Though my P226 is probably around 10k rounds, and the NP22 is around 2k or less.
