Interesting. I need to do more work with my 11lb and 12lb spring and see. It didn't change my velocity and shockingly it seemed my brass throw may have been shorter. I need a spotter or camera to see what is going on.

I've noticed accuracy differences in my 1911's with different spring weights too.

Although, keep in mind the guy in the video appears to be running a 9mm, so the spring weights he's using won't be the same as what you'd need in a 10mm or 45. The general concept is good though.

I'm not so sure about that being a 9mm.   He said he runs Major power factor of 170.


Thanks for the video Shadow, good information.  :)

I think you can just barely make major 170 with 147 gr +p+ 9mm.  The Buffalo Bore load would work out to 172, as would the Underwood load.

Plenty of guys run Major with 9mm. It's a lot easier to do in a 1911, since you can load to a much longer OAL. Look at the brass when he's shooting. Looks like 9mm to me.

This is info for 1911 clones or simular style, I think the Glocks, S&W10xx and even the EAA Witness lines are different as far as lock up and recoil are concerned and how the recoil springs work to help maintain lock-up as compared to the 1911's.

Everything becomes relevent to a certain extent so we just have to study what works and what doesn't!  ???

Awesome video!  Thanks for posting it.
Gun Control?  Oh yes, the theory that becoming a victim is somehow morally superior to defending yourself & your family.  Makes perfect sense.

Interesting video.

He does say he is shooting a 40 cal several places in the film.

Excellent video ....

I might add ... notice that while the rearward slide speed DOES seem a bit reduced with heavier springs, the VERY SMALL but crucial BARREL UNLOCKING SPEED seems **NEARLY** unaffected by the heavier spring. 

Like I've postulated before, the best way to affect ACTUAL unlock speed is with slide mass (and, in a 1911 only, the firing pin stop geometry).  The recoil spring doesn't make a big enough difference SOON ENOUGH to change the outcome of what we might call an "early unlock".  At least, that's how it *SEEMS*.
