Light Pin Strikes, Timney 3lb & SlideFire

[sharkbit]

I've noticed quite a few fail to fires from light pin strikes using the timney 3lb trigger and slidefire stock. Is there anyone else who has experienced this same problem running this kind of setup? They tend to occur more frequently after a few hundred rounds at the range(while bumpfiring), so I am thinking it might be due to the gun getting dirty.

I have the non-rotating pins and the timney trigger is securely mounted with a 22 guage steel shim piece underneath it to prevent set screw damage to the plastic. I am running fed bulk ammo.

Anyone else have these light strikes and find a way to fix the issue?

Thanks,
Sharkbit

I would suggest you search and read all the previous threads on this light strike situation.....then after you are confused, simply remedy the situation by lighting the fireing pin rebound spring. This is easily accomplished by shortening the fireing pin spring (clipping it) to a length about 1/8" to 3/16" longer than the end of the pin..........best regards Plum

I also trimmed my Spring.... seemed to help Some

I have also Noticed that an issue can occur with the Rounds I use... Meaning... I have had some Federal that are a bit off and jamb in the Mag....
Since you use federal... Try another box and compare results... That was my issue last Time out... so use that box on my .22 pistols ...

Be sure the mags are stacking perfect......
Be sure the Rounds are clean and not Gritty...
Dont Have Bolt to WET when cleaned and Lubed...
A Quick Clean in the field may help...
be sure Trigger set screws stay Tight.. If Trigger loosens (mine did) trigger wobbles and will cause FTF...happened to me 2x


Anyways... some food for thought

I have the same setup and am having the same problem. I noticed that I have a lot less problems when I really watch how I load my mags. I pull the finger-assist thing just enough to slide one round in than release it for a second before loading the next round. This helps set it in place correctly. When my friends just pull the finger-assist down and drop a few at a time in, it jams up. When you look at the window down the side, the bullet heads must alternate back and forth. One towards you, one away and do forth. Don't know why, but this helps me a lot. I'm guessing it's causing just enough resistance while loading, and the trigger is being pressed so closely to when the bolt is returning to battery, that the hammer is following the bolt and hitting it it just before it's back in place because that tiny hang-up is slowing down the bolt just enough. This is just the theory me and the range buddies concluded. Might try the spring clip though.
Ya there's a lot of things happening in a very short amount of time and everything has to go just right 25 times in a row for a full mag dump. I keep getting asked why I do it and it's not worth it for how picky it is, but once they do it once they say "Ok...now I see"

the bullet heads must alternate back and forth.

Bullet heads? What's that? I don't know where this term originated, but it's incorrect.

The projectile in the end of the case IS the bullet; the complete round is called a round or a cartridge.

Only Hollywood and the news media call cartridges "bullets".

How fast are you guys emptying the mags with the slidefire?

The projectile in the end of the case IS the bullet;

Dictionary-
Head:
8. Adj. the foremost part or front end of anything or a forward projecting part

I was talking about the front or the round, by definition the head. Head of the bullet=bullet head. I grew up calling them bullets, and was never in the military so I never was taught correct terminology. sorry if I offended anyone.

25 round mags in just under 2 seconds. Stav can do a 50 rounder in around 3.5

and just so you know, loading 1 round at a time in the magazine is the method recommended by s&w in the manual. the only 2 problems ive had in over 3k rounds have been feeding issues due to damage bullets.

You didn't offend. It's just important we use correct terminology.

 

[Dikinalaska]

My terminology was by definition correct terminology, it just wasn't the preferred terminology. But dually noted, they are rounds from now on

I load every magazine I own 1 round at a time
