STI DVC Limited Stovepiping

[adamastergunner]

I reload my own ammo  and wanted to know if my STI DVC is stovepiping does that mean my recoil spring is too heavy or too light. Thanks.

Need some more info.  Is it the last round of a mag, random or every round?

[adamastergunner]

It happens every few rounds when firing through a full mag.

What caliber/bullet/velocity?  The ones that don't stovepipe, do they just dribble out?  If so you need more powder or a lighter spring.

 

[adamastergunner]

It is a dribble.

Then you need more powder or less spring.  What caliber/bullet/velocity?

9mm 124gn 130pf

Weak grip, dirty or dry gun can contribute.  My new STI 3 gun had an issue with the extractor I think. I was a new shooter  at the Tim and sent it back to get fixed.

As @shredstated, you need more powder or a lower weight recoil spring!

 

IMO, 130pf is on the "weak" side of the 124g power curve.  Grab a lower weight recoil spring calibration pack and find out what gives you correct function with ~3-4' ejection at 4:00 o'clock of your spent brass.

Of course, this all depends on the extractor and ejector functioning correctly along with the pistol being clean and properly lubed.

This.  Start with a well cleaned and oiled pistol and an 8 or 9 lb spring and work from there. 

 

If somebody has been mucking with shaped firing pin stops and heavier mainsprings, then undo that too.
