Tarus-Light Hammer Stike????
9/17/2010 8:53:46 AM
Have a Tarus 24/7 45acp, love the gun but with my reloads with silver win primers it will fail to fire about 1/3 of the time. Never had a failure with factory win brass color primers. Hammer strike seems realy soft. All misfires run through my 1911s easily go bang. Does it need to go back to factory???? I know what they will say "if it fires factory, its good for us" Help & Thanks––Hayboy

If factory works, you're probably not seating the primers enough in my experience. Some pistols may not like the harder primers either, but Win primers are supposed to be pretty soft. Try CCI and then Federal primers to make sure, but seating would be the number 1 suspect to me. For all we know it's Amerc brass too ;)

My geuss is a "weak" mainspring" or striker / firing pin spring. I have heard this alot with Taurus and i am having this issue with my 454 raging bull as well. I am using CCI 450 's and they almost always misfire, but will fire the 2nd time. I AM seating them deep enough as i use the lee auto prime hand primer and i can feel when they stop against the primer pocket then give it another push.
I feel the CCI's are hard and sometimes make "weak" springs work to hard. Check out the site below, and i don't know how to hotlink

Update––
New firing pin and mainspring was the answer. The FP was .0001" wider and .0002" longer and was designed with a round head instead of the older flat head. Total cost from Taurus was $15 shipped and took about 2 weeks. They would not ship the parts for free, but if i sent in my gun they said it would or been free, but i would of had to pay $40 shipping to get it to them
Anyone having misfires should try a new FP and/ or mainspring.

I had the exact same thing with my PT1911. Light strikes on about half of my reloads with magtech primers. The reloads fired with out problem in other firearms. It also fired all factory ammo perfectly. I replaced the mainspring with a $1.00 one from DPMS. Problem solved. 3000 rounds and no issues. There was also no perceived increase in trigger pull.
