Troubleshooting X5 Legion

Recommended Posts

Posted (edited)

Bought a new X5 Legion and am sorely disappointed with reliability after the first range session. Gun has been stripped down and lubed before the shot.  Shooting a mix of Fiocchi 115gr and Browning 147gr resulted in several FTEs with multiple stovepipes per magazine. The 115gr was definitely more trouble prone but the 147gr suffered at least two stovepipes per 10rd mag.  In general, extraction seemed weak with rounds ejecting straight up and landing on my arms or back on the pistol.  This is the first SIG I’ve purchased, coming from Glocks but liking the overall grip on the X5 given a hand injury which prevents full use of my right hand. While I was very impressed with the accuracy, the reliability has me questioning the purchase.   I’ll be contacting SIG on Monday but in the meantime is there anything I should check/change if I can get to the range again today?

Sorry to hear the trouble. When you stripped it down and re-assembled it, did you align the notch of the extractor rod correctly? When you move the extractor manually by, say, a screw driver, do you feel a tension? Just my thought.

Put in the 12# recoil spring and try again.

Range update: installed 12# spring and that seemed to solve it although perceived recoil increased (which could be more mental than anything).  Still exceedingly impressed with the accuracy of the gun, which was shooting as well or better than my 1911.  

 

Thanks to all that offered help and look forward to getting more into different pistol events this year.  My background in handguns is only from the military so the learning curve is very steep.

The X5 can behave as you described for the first several hundred rounds. After that they run like a clock. Most likely nothing to worry about.

I have two “Standard” P320 XFives and just received my TXG grip module that I will use to replace one standard grip module. 

Shooting a standard XFive with the standard grip module, I agree with a perceived increase in recoil with lighter recoil spring, Jtmilne. I have a Grey Guns Fat Guide Rod and 15, 14, and 12 lb rated recoil springs along with the stock SIG recoil spring & guide rod assembly. I have not yet shot the 12 lb spring because of my experience with the stock, 15 and 14 lb springs. The sights settle back to proper position best with the 15 lb spring that came with the GG Fat Guide Rod. Going up to the stock Sig recoil spring assembly or down to the 14 lb spring makes the pistol recoil more AND the sight picture more unstable and slower to recover.

- I’m shooting factory Federal 115 gr AMMO at 129 Power Factor until I can get my Dillon press set up.  

- My casings eject 3 feet to my right. The last one ejects differently on the empty mag.

- I am going to weigh both pistols in Standard XFive form and then with the TXG grip module.

- I will be shooting the heavy TXG module this weekend under both of my Standard XFive slide assemblies - one has iron sights and one has a Romeo1 on top of it.

I found the13# Wolfe 1911 spring to be the sweet spot for me.  This is in a non legion X5 with the TXG grip mod and a Spring Precision tungsten guide rod.  With my loads, the 12# would not eject the spent brass all the way.  The 14# spring is not hateful, just like the 13.
