light primer strikes

[asphaltcowboychip]

I recently purchased a Les Baer from the market place in GREAT condition. It's a premier II. The round count is or was at 300 and me and my buddies put another 80 through her. Well one of 5 people who shot it (I like to share at the range) had 2 light primer strikes he was the only one who experienced this. Guys before and after did not experience any issues. My question is can this be due to the shooter having a limp wrist ?

No.

Ammo is the likely source.

Ammo being shot was winchester white box. Could it of been 2 random primers?

Any other possible issues. Firing pin is not broke.

It could be an anomaly. I personally have never seen LPS from limp wristing.

Likely just random luck that the LPS occurred with the same guy. Primers not fully seated will fail to fire first go round and then fire on subsequent hits.

If the gun fails to return to battery, slightly out of battery, the pin can strike off center and fail to fire. The anvil of the primer has gaps (the anvil kind of looks like a radiation symbol in plan view), off center strikes can land in the gap. It is possible the one shooter was riding the slide and that can lead to the gun failing to return fully to battery and off center strikes.

You can also check the gun for return to battery, a very tired recoil spring can cause this, but is a real long shot. You can lookup the return to battery test on goggle.

It is easy to detect the return to battery issue as the LPS rounds will have an off center hit.

Again, likely the ammo though.

Thanks for the info gentlemen. I'm going to take it to the range here in the near future and see if I can induce the LPS again by riding the slide. Thanks again for the help.

It's amazing how that problem just manifested from one specific shooter. Is there a physical difference with this particular person? Does he have an unorthodox way of doing things such as, trigger slapping, trigger finger placement. His grip on the gun, did you notice if he push and pull instead of pull and push? Well to prevent the LPS I suggest omitting this particular person from your range trips - problem solved.

Sorry couldn't help it. . Did the ammo with LPS ended up going off with a second trip to the chamber? If by chance you still have some ammo from this same lot inspect it for high primer seating. He may have been the lucky one to pickup the problem ammo.

Hahaha JTROKS I'll let him know it may have been because he's a pansy.

Check to see if the firing pin can protrude through the firing pin hole without any resistance.

asphalpcowboychip,
Take the barrel out of the gun and do a plunk test with a box full of the WWB rounds. Are they a snug fit? Do any of them fail the plunk test?

If the rounds are fitting the chamber with resistance and the shooter limp wrists a little more than the other shooters, it may be that he's absorbing the slam of the slide just enough to prevent the round from going 100% in. You can ride the slide and see that you can pull the trigger when the slide is 99% closed, but not 100%. You'll also see that when the hammer falls, it will move the slide forward so you won't be able to tell that the slide was not closed after pulling the trigger.

If your gun has really snug chamber and throat dimensions and the rounds are slightly big, you might run into resistance as they are loaded into the chamber. That can lead to failure to go into battery or more frustratingly, light primer strikes. I say LPS' are more frustrating because it's intermittent and it seems that everything should have led to a normal shot.

The plunk test will find any problem rounds if that's the case.

If that Les Baer is under the 500 round mark it's still not broken in. If the barrel is still hanging up at 1/8" to full battery maybe your friend limp wristing failed to close lock up at full battery. The lower part of firing pin stop will receive most of the impact of the hammer and may just send enough energy to the firing pin causing a light strike on the primer. I've seen it on my 1911s that are hand fit even when the shooter is not limp wristing.
