Ruger SR1911 jumping quite high??

[saxsaxsax]

Hi all,

Just bought a Ruger SR1911, I also have a Norinco Government one. What I realized is that the Ruger is heavier (don't have the exact weights but feels much heavier than Norinco). Otherwise they are essentially identical parts-wise with some embellishments on the Ruger.

When I shot the two I also realized that the ruger has a much higher muzzle rise and jumps all over the place comparing to the Norinco, even though it's heavier...Can some one please offer an explaination?

Different recoil springs maybe?

The spring on the Ruger is actually heavier than the Norinco........

The heavier spring might just do it.

The heavier spring might just do it.

Really? I always thought that the heavier the recoil spring the more force it absorbs and thus reduces recoil?

The heavier spring resists the recoil more forcefully from an earlier point in the cycle, that means a longer, sustained push being transferred back to the user, but less frame battering at the end of the cycle.

hmm that makes sense. Longer push time translates to more energy delivered to my hands. Highschool Physics coming to good use! =D

Thanks for the explanation! Now I can sleep at night =)

Someone can correct me, but I believe the Ruger has a 24lbs spring vs. Norinco's 16lbs spring. That = hold on to her!

I run 14lbs springs in my 45's.

^ do you run handloads or factory? With factory loads I would think the pistol is taking a bit of a beating, I could be wrong...it's happened before?

The 5" SR1911 have a 18lbs. recoil spring.

The heavier mass of the Ruger's slide as it cycles will also contribute to felt recoil.
