I took my PT 1911 to the range Saturday. I ran one magazine through it and put a loaded one back in it. Handed it to my father in law and his first trigger pull was a missfire!! We ejected the shell and the primer had a dent in it. I put it back in and it fired fine. Every round after that fired fine. I was using Winchester White Box ammo. Is it normal to have light primer strikes from time to time with .45s? Is it the ammo? This is the first I've had with a pistol. Most of the time I use WWB for the range.

i have had one ftf and it was a light primer strike as well. it was with a reload, but i was using winchester primers. i dont know if this is just a coincident or if win uses a little tougher metal in thier primer cups. just my .02 worth.

Thanks. Winchester is the only ammo I've used in my .45. I'll try others but I like the WWB because of it's price.

I've fired thousands of WWB in .45ACP without incident, though that doesn't mean you didn't happen to get one round with a hard cup. Normally I'd ask if the FP channel was clean, but the PT's are a bit loose in this area from what I've seen so that probably isn't the issue.

I have had a couple of hard Winchester primers in my reloads. Hard enough that the FP dent didn't change nor would the round go off after multiple tries... Tough primers. ;D

The whole gun was fairly clean. Like I said, I had only one mag, 8 rounds through it before it happened.

I had some what looked like light fireing pin strikes in some 357 Ammo, the first thing my gun smith asked was it winchester white box I said yes and he said that winchester uses harder primers compared to other company's I told him I use it all the time and he said it runs in batches and can be any cal.
I have fired thousands of WWB in almost every caliber and other then 2 misfires I've never had any problems. Mine also fired on the second strike. I figure 2 out of several thousand is not bad so will continue to use winchester ammo.

I have never had this happen to my .40 or my 9mm when using WWB. I thought maybe something was wrong with the gun. Glad to hear it is an ammo thing. I appreciate all the info. Thanks guys.

The weight of the firing pin is the fall of the hammer and that is determined the mainspring The normal weight of the PT1911 should be completely capable. Not only is there the issue of the hard primer, but a deep seated primer can mimic the light primer strike.

I just purchased a new PT 1911 in 38 auto. The gun shop had 2 identical pistols. I experienced light primer strikes in both pistols whenever I rested my thumb on the safety. Pistols seemed to work great when not using a grip with my thumb on the safety. I plann to call Tauras to see if this is an issue.

My wife has a Colt gold cup .45 and of course thumb on safety works just fine.

I've only had opportunity to shoot 40 rounds of the 38 super (factory ammo).

Anyone else use a thumb on safety grip?

Good morning Mike and welcome to the forum. Although I have a PT 1911 in .45 ACP I am not much of a 1911 smith. I don't even know if the mechanics are different on the .38 Special. If my PT 1911 started having light strikes (like my PT 145 did) I would detail strip the slide and look at the FP and channel for any dirt/grit/grease and/or any changes to the FP itself. It almost seems that the fire control group will need adjustment as the safety mechanism is inhibiting the full movement/force of the FP moving forward.

Just sounds like a hard primer, the 1911 by design is pretty reliable when it comes to primer strikes in general. If it starts to happen again on a regular basis, i would pull the firing pin out and inspect it. Also check to make sure nothing it inside of the channels that may block the pin from striking with full force.

Mike, some of the PT 1911's come with a real stiff grip safety and when you choke the gun with a high grip enough to rest your thumb on the safety you might not be disengaging the grip safety enough, try and bend the safety spring forward to decrease the tension and see if that will fix it.

Yes Winchester primers are harder than some other brands. Yet the only place that has been a problem for me and many others is in a competition gun with a very light strike (the reasons for that are a subject for a different thread), every stock gun should have a heavy enough mainspring that the brand of primer should not be an issue.
A far bigger issue is primer seating. My attitude, backed up only by personal research, is that if the primer goes off on the second hit - it was seated by the first strike.
And finally - one FTF is not enough to indict either the gun or the ammo. This is not a pattern of failure. At this point, if I were you, I'd shrug my shoulders and proceed to shoot more.

that would be chambered in the 38 Super!
the Pt1911 has never been chambered in the 38 Auto, Just FYI.
The 38 Auto was discontinued some time ago in favor of the 38 Super.
In any regards I honestly can see no reason that having the thumb on the safety would cause a misfire?
My Pt1911 in 38 super (or even the 45 acps ) will fire upside down, right side up, gangster style on their sides., thumbs anf fingers about anywhere except in front of the barrel.

How do you know it won't fire with your finger in front of the barrel? Have you done the experiment? :D

I was having the same problem only with Speer ammo. Was advised by "Olfarhors" to take a look at the FP and its channel. I throughtly cleaned the FP and channel, also extractor while in the area, and all has worked fine since.

And I am betting that they were pretty gunky. I was amazed when I disassembled and cleaned mine. Many say to use a dry lubricant like teflon, if any, as a wet oil will collect carbon and unburnt powder. Or oil it and clean more frequently.

He-He-He, yea thats their real names~!
We affectionately refer to them as Twiddle Dumb and Twiddle dumber!
I am one that basically only uses a squirt of Rem Dri lube (teflon solution) in the firing pin and extractor holes, I flush them out pretty godd with Gunscrubber than relube with Rem Drilube, I clean them out maybe once a year and so far have had no problems with any as to firing pin/spring related issues?
The Rem drilube also works wonders on magazines and no catching all that nasty debris from firing.
Anyway works for me.
