finally took my new security six to the range today and had a bit of an issue. out of 50 .38 special (mag tech) i had 2 failures to fire. it looked like the had a bit of a light primer strike but i restruck them in single action and got a solid hit but no bang.

i fired another box of 50 blazer .38s without a hitch.

should i cough it up to magtech being cheap ammo?
 
2 failures out of 50 is no good for me. My revolver needs 100% fire reliability. Try a different batch of ammo because it could be an ammo problem instead of the revolver. If it continues then check the hammer spring (main spring). Years ago some folks would cut some coils out to lighten the trigger pull. The problem is if you cut one too many you get failures to fire. Any good gunsmith should be able to change the spring with a new one if this is the problem.
 
Note that when a primer fails to fire, there will be no cratering and metal flow of the kind we associate with a normal "fired primer", causing some shooters to believe the primer strike is too light. If the other primers fired DA ignited properly and had a normal appearance, I suspect you had some dead primers in that box of ammo.

I would avoid that ammo unless you get it cheap and want to shoot it up on the range, but don't use it for serious purposes.

For a quick fix on one of mine I added a little nut nude the hammer spring just above the bulge on the strut. Then I replaced the spring when I got one. I believe the 10-22 inspiring is interchangeable. I carry a couple in my kit.
 
ammo related not firearm related at least I don't believe so. For some reason my Ruger Security Six hates magtech ammo, but it shoot everything else 100%.

Federal
Remington
Blazer
reloads
winchester

all has been 100% on the misfires from magtech if I fire a second time they go off. And my Security six is factory.
 
My security Sixes

I have a few Security Sixes (Sixes, to identify the Security- Service- and Speed Six product line from Ruger), bought through the years since thr mid-seventies. None have had difficulty igniting primers in a wide variety of brands of brass.

Weak (either cut or just old, though age is not usually an issue with the Sixes) as Black Knight mentioned is probably the most likely, two other candidates for the cause of light strikes are:

problem with the transfer bar, either foreign material, thinning from peening or being out of position due to parts wear

The firing pin (f.p.) being slowed by gummed lubricant or other problem or the f.p. being too short.

For an expedient test, try this:

Open the cylinder, put your finger on the firing pin hole and pull the trigger. (You will have to manipulate the cylinder latch to free the firing mechanism.) You should feel the firing pin distinctly. Now do the same with another revolver. Do they feel equally intense? If the Sec. Six feels less intense, that would be a clue that points to the gun as a cause.

I suspect a bad batch of ammo which is probably rare and would be apologized for by the factory and rectified somehow as well.

Good luck

p.s. Since Bikerdoc and Mr.Revolverguy have had similar issues with Magtech ammo, checking rim thickness would be a good idea. If the cartridge is not held close enough to the breechface. the f.p. may not deliver sufficient impact to the primer. This brings another thought. Is there excessive fore-aft play of your cylinder within the frame?

Fortunately, I've never had an issue with Magtech in my Security Six (1982)

Re acronyms: I think context is needed to decide what is meant. FWIW, I assumed the OP meant failure to fire since this is a revolver subforum.
 
Lost Sheep's post is worth revisiting. He covered what caused my LPS (Light Primer Strike) issue with a GP100. I had some dirt on the back side of one edge of my transfer bar. Didn't happen all the time, most frequently on CCI primered handloads. I spent lots of time examining my reloading process, and even changed springs before I found the issue.
 
A friend of mine was having intermittent FTFire issuse with his .45 caliber Blackhawk.

He brung it with him when he visited from NC's capitol city.

The firing pin tip had been flattened, and was only protruding from the recoil shield about 2/3rds of the normal distance as observed in my Blackhawks.

He said he was gonna send it back to Ruger for a replacement. No word on whether he did or not.

Might be worth a look-see.
 
Could be the ammo. But probably a good idea to check for gunk or junk. Checking with your finger that the firing pin goes in an out freely is also a great idea.
 
There's a lot of good advice here. Allow me to add another thought.

The mainspring of the Security-Six is secured by a strut. Some folks lightened the spring by filing down the struts' shoulders. This is something you should also check.

If your other ammo is working fine, I wouldn't worry about it.
