Light primer strikes.

[firefighter1635]

Are they common on a pistol that has had a trigger job? I was out shooting my CZ 75 Compact (9mm) this morning and out of a box of 100 Winchester White Box I had one light primer strike. Total 150 rounds through it since the trigger job was done with just that one light primmer strike.

Yes. IF the person that did the trigger job clipped the mainspring. It is easy to go overboard on the clipping.

I did a Taurus PT809 and I clipped 3 coils out of the mainspring in addition to stoning the engagements. which made for a freakin nice DA pull and a crisp 3 pound SA break but it wouldnt shoot WWB. Light strikes like crazy. SO I got a new mainspring and clipped only 2 coils, DA pull increased marginally and no more light strikes. Still has a sweet 3 pound SA break.

Part of a trigger job on a 75 were they either clip or insert a reduced power mainspring is to also replace the firing pin spring with a reduced power spring. Also a good fix is to shoot only federal ammo. Those primers are soft compared to WWB

OK Josh, the first thing I do on all of my SA revolvers is cut two coils to start with and it sure helps the trigger pull. So I told a gunsmith that I did that and he chewed me out. I know it is a poor mans trigger job but my revolvers aren't too shabby. I have one revolver (Vaquero) that is tricked out completely. I took the Wolf spring out of it and put it into another Vaquero that I have and switched it back and fourth between the spring that I had cut down and out of all honesty my spring feels better. The Wolf spring is a nice spring but IMO if you can cut it down without messing it up (like I just did on my GP100, oops) then I say order the Wolf spring at that point. But if you cut it down and it works, IMO that is fine.

What is your opinion Josh.

Yes, by cutting the mainspring down too far you can have a "Light primer Strike."

First thing i'm going to have to do is shoot my SD ammo and see how it reacts. If I get light primer strikes on that i'll be taking it back to my gunsmith. Afterall, $150.00 for a tactical trigger job specifically for being used as a carry concieled and having issues is unacceptable.

WWB was the culprit. Shot many different brands today. No light strikes. Even spoke with my gunsmith, he concures.

If it works it works.. Clipping a mainspring is no different than installing a reduced power one. The 'smith' you talked to is probably an armorer.. Armorers are instructed to NEVER alter any part of the fire control system of any weapon they service as it voids the warranty and can make them misfire..

Ya, 10-4. So that revolver I was working on, I cut the mainspring. You know the action is smoother since I cut the spring and polished the action, but I think I need to take about 3/4 coil off, and then we will see. It sure was fun working on it. I APPRECIATE YOUR HELP ON IT JLA. Thanks.

Yessir! Fixin guns is fun and gains you knowledge and experience. HEck i did a 'counter repair' to today at the gunshop. A Taurus Millenioum .45. Dadgum slidestop gept popping out to the outside of the slide. Turns out Taurus and thier wonderful QC dept sent it out with a bent slidestop lever. So now I know how to fix yet another Tarus POS in order to keep the customers guns in thier holsters, not at Taurus for more shoddy repair work..

That's why my favorite trigger to work on is on Mosin Nagant Rifles...


Any trigger job that starts with...

Step 1..."Take an empty beer can and...." is for ME


Also I too have worked on MANY guns, and have screwed up more than several along the way. BUT EXPERIENCE you always PAY for, one way or the other....


But the cardinal rule I have learned working on guns, or cars, or anything mechanical, that is the BIGGEST one for me to remember EVERY time I putz around with ANYTHING....



"It is always a HELLUVA lot easier to remove just a LITTLE metal at a time multiple times and keep checking until you are ALMOST where you need to be, than it is to put the metal BACK if you remove or cut off too much the first time, or ever!"

Violating THAT rule has cost me more time and money and heartburn than just about ANY other....

Oh yes. In five years when my home is paid for I will do a frame up resto on it. Until then everyone has to put up with the dent. Look at the bright side though, it makes an ideal hunting rig.
