Mod 41 Eject fails - an observation on ammo variability

[armorer951]

Another variable is the recoil spring. Be sure if you have a cut or aftermarket (non-factory) recoil spring in your gun that the cut end of the spring is to the back, inside the frame cavity.
If the recoil spring has a cut end and this "ubfinished" end is facing forward, the spring can hinder the slide's movement enough to cause reliability issues. Even worse, the tail on the cut end, if facing forward can get caught in the space between the hole in the slide and the guide rod, and tie the gun up.

I don’t want to jinx myself and say that the proof is in the pudding, but since polishing my breech I’ve not had any more ejection failures.

In fact the gun has done so well that I’ve won the last two Steel Challenge comp’s at my club with it - including some reasonably decent string times around the mid 10s with a best run time of 2.4.

Prior to polishing the breech I would suffer at least one and up to three or four ejection failures in about 100 rounds, despite having employed all of the usual mitigation ideas for ejection failures on the M41 (as I have mentioned here previously), upgraded to a Volquartson extractor, meticulously cleaned after every shoot, lightly lubed my brass, use CCI Standard Velocity ammo (and tested countless other types) and so on.

At this stage I’m not sure that I want to call this “solved” but I’m very happy with the outcome so far and will hold off having the breech actually reamed by a gun smith....... for the moment at least.

If I live long enough, I may own a Model 41, some good observations above on maybe why they may seem so finicky on ammo and why some run flawlessly and others not so much. Thank ya'll!
