Fail to fire malfunction

Good afternoon, hope everyone is doing well.

While at the range on Friday, my SA Ronin, 4.25 9mm had a lot of malfunctions.
Springfield/Mec-Gar 8/10 rounds, was not isolated, happened with all mags, every mag.
115 gr JHP Fiocchi Target Max

Everything seemed to feed correctly, felt and look like it was locked up, hammer would fall, no fire.
Thumb the hammer back, pull trigger, fired.

Not sure if this was a limp wrist issue, or something else, any insights would be great.

Thank you

Nope , Limp Wrist not a potential factor . I'm going to go out on a limb that it doesn't have 1/4 thick crud built up in the chamber .

That narrows it do one set of circumstances :

The Firing Pin Strike doesn't have just quite enough smack on the Primer to consistently ignite it .

Could be firing pin not striking hard enough . Could be that brand & lot of ammo needing harder than typical impact to ignite . Could be a little of both coming together.

Check that everything in the lock work of the pistol is clean and properly lubricated , especially the firing pin channel .

Inspect the ammo , make sure all the primers are consistently seated , and fully seated .

Ideally test other ( major band name , made in USA ) ammo in your gun , and test that ammo in other guns , known to be reliable .
 
Agree with @Biggfoot44, a common culprit is the firing pin channel. It starts when lube seeps in or cleaning solvent is introduced while scrubbing breech face during cleaning process. That moisture attracts carbon buildup on firing pin spring coils as well as firing pin and wall of said chamber, limting the travel of the firing pin. It does not take much buildup to retard the strike enuff to cause a light strike on primer.every so often, I run a .22 cal brush through the chamber, followed by a few acetone soaked swabs and then a good blast of canned air. I Do the same with extractor channel. Firing pin and spring, as well as extractor get reassembled CLEAN AND DRY.
The Ronin is an awesome gun, hope this helps.

Yes , on the gun side of things , cruded up FP channel, followed by toss up between broken FP tip , and " custom trigger jobs , that took lighter springs a half step too far .

On the ammo side , could be a Lot of slightly harder Primer Cups .

My druthers are l like a hefty firing pin smack , even at the expense of couple oz heavier trigger . I want a big margin of error to have it Go Bang, Every Time , with virtually any ammunition.
 
I had the same pistol except mine brand new would not return to battery using 115gr. It required a strong smack to the slide to get into battery and it was like slow motion when it did. It occurred on all 12 of my magazines. I called SA and they suggested I return it...and wait 6 weeks for its return. I have no doubt they could figure it out, but I wasn't willing to wait.

I had a local well known 1911 shop check it out. The gunsmith said the pistol should never have passed QC. First, there were burrs on the slide and frame which were addressed. Second, the raised electro pencil markings on the bottom of the slide caused to much friction and and were addressed. Third, the recoil spring was only 9#, if I remember correctly. The shop suggested using no less than 124gr ammo, and installing a 12# (?) spring. It ran fine after those improvements. A few weeks later I noticed the bluing was degraded down to bare metal on the grip. SA did fix that for me for which I was grateful.
 
Do the #2 pencil with eraser end check. Make sure the weapon is unloaded with no magazine in.
Let the slide go forward fully into battery.
Turn the weapon skyward so the barrel end is facing up.
Insert the pencil eraser end first
Pull the trigger. The pencil should be launched out and away from the weapon.
It’ll go up a good distance.
If it doesn’t. Try it again. If it still doesn’t then you’ll need to clean the firing pin chamber, spring, and pin.
 
The going on the restrike sounds like it’s not fully cocking, or slipping to half-cock when the slide cycles…which could be weak ammo.

Have you used this ammo before, and was it reliable then?

Either that, or have you cleaned the firing pin channel recently, and if so…did you lube them? This can be an issue…try to keep lube to a minimum on the firing pin & firing pin spring.
 
Thank you everyone for all the advise, I will start working through the issues and corrective actions this weekend.

to answer some questions,
I have used this and other 115gr ammo without issue in the past.
Currently do not have another 9mm to fire the ammo with
Do not have spent casing to inspect primer strike.

I did, which I forgot to mention, replace the trigger with an aftermarket solid trigger, so I will reinstall the OEM trigger before I go to the range again. Just the trigger was replaced, none of the other fire control parts

nah, we get paid in Snickers, or Milky Way, or Mr. Goodbars from the person asking for help

they get a "bill" in the mail, and if they do not pay up....

we make a call to ICE and report them as illegals.

I suspect that’s your issue. Sounds like the mainspring wasn’t reinstalled correctly.
