    PT 145 light strikes

    To start off, I have gone through the 6 pages of topics that came up on a search for light strikes. Some are similar to my incident - I am just posting for general info.

    I have 200-300 rounds through this GEN3 145. yesterday at the range I had 4 light strikes that did not fire on the first hit OR on the second (double strike feature) attempt, either.

    They were from 3 different brands of ammo, one type was reloaded. they did not occur in sequence. Some went, then another light strike, followed by a few more successes and another light one.

    All light strikes looked the same - an obviously small dimple in the primer. All fired successfully in a different gun.

    These failures occurred within the first two mags I attempted to fire. After trying the different mags and ammo, I did a quick field strip and put a drop of oil on the striker channel area. From there on out I fired another 50 or so rounds from 3 different magazines without any further incident.

    I assume there was either a small chunk of crud, or it was a bit dry and the lube either moved out the crud or something.

    I am considering removing the striker for a look, but now it seems to be fine. Should I go deeper with the apparent fluke/problem now gone?

    On a positive note, I have had a few minor magazine problems early on. These were non-existent yesterday on 3 mags (one has a clipped spring).

    Re: PT 145 light strikes

    I had the same kind of issue recently. I tore down the striker assembly and was amazed at how much crud was in there. Definately enough to cause light strikes. Also had a broken firing pin lock that was the main cause of my issues. I do think though that a dirty striker/channel would cause light hits and it is worth inspection if nothing else...

    Thanks, that is good enough for me - I'm going to have a look.

    Re: PT 145 light strikes

    The vast majority of these light strikes are caused by not properly cleaning out the striker/firing pin channel in the first place.

    You need to squirt GunScrubber into the channel until it runs out the other end - and then reverse it and do it again from the opposite direction.

    Then lube with a dry lube such as dry graphite. It you must use a wet lube, then one SMALL drop of lube into the channel is more than sufficient. FWIW, wet lube attracts dirt, line and other debris while dry lube doesn't.

    Re: PT 145 light strikes

    I had the same experience with mine on reloads. Light strikes with small dimpling, subsequently fired the same rounds in my PT1911 on the same visit. I took my firing pin assembly down and cleaned it, although I did no see much dirt/debris in there. No problams with the last outing and about 80 rounds through. No FTF with hardball 230 grain, still haven't tried pumping up the volume on my 185gr SWC plated reloads to see if they will feed/cycle better. I just read the thread on the blown up PT145 and have bigger things to wonder about it seems.

    I took it out and cleaned it, that was easy - I still had some issues with reloads, but WWB ran fine. I might need to try a dry lube on it next.

    Personally, I don't quite buy the story on the blown-up gun. It's virtually impossible for the major ammo maker's machines to double-charge a case.

    Anything mechanical can fail and at the rate they are running ammo it doesn't surprise me.
