1. Your own handloads? or a count of commercial rounds fired ?out of a batch of 200
Stovepipe usually occurs when slide does not go back fully to eject spent case.200 9MM I had one stovepipe. First ever with my S & W Equalizer.
Trying to figure out why. Light load?
I appreciate all the comments. The limp wristing is possible but I doubt it. While practicing, I did shoot a few rounds with my off hand and a few single handed but as best that I recollect that was not the stove pipe.1. Your own handloads? or a count of commercial rounds fired ?
2. Could be light load, limp-wristing, or lube exhausted/needed on the rails.
3. Light-lube the rails as first option.

Another variable is new/newer recoil spring rate could be more than a pound over well worn/broken-in recoil spring.RMR 124's Round nose ... HP 38 4.2 Grains ... 1.112 LOA
Labradar showed an average of 1015 FPS ... Factory Hornady showed 1131 FPS a week ago.

The 200 rounds in the new Equalizer were for familiarization.
30 Rounds of RMR 124's Round nose
HP 38 4.2 Grains
1.112 LOA

Factory Hornady showed 1131 FPS a week ago.
A week ago, same loading in a standard M & P 9 with 4.2 Grains of HP 38, and OAL of 1.112 gave me 1038FPS. CORRECTION
Lube - I cleaned it today and thought that saw a lot of lube on the slide and made a note that I over lubed it when I cleaned it.
Will have to go with a mystery unless you guys can analyze my data better.
Yes, there are many reloading and shooting variables at play.Nobody, nobody can tell you why one round stovepiped. To many possibilities. Especially with handloads
The next round in the magazine is sitting higner then normal. It bumps the fired brass off the bolt face, as its moving back.
I regularly shoot 9mm at under 950 fps in several pistols.Seems i remember 9mm clocking a bit higher then your #s. I think you might be on the threshold of functionality, load wise. Perhaps bump it up a few 10ths.
As the slide moves back with the fired case, the magazine allows the nose of the next round to pop up higher then normal.What do you mean by 'higher than normal'?

The fired case is knocked off the slide/bolt face & out from under the extractor.
Not necessarily.So all stovepipes are caused by this?
Recoil springs are consumable part that gets replaced when worn/weak but many shooters never replace the original factory springs.I regularly shoot 9mm at under 950 fps in several pistols ... A few Star pistols; a 30M, a Model BM. An SCCY. A Tisas, and several other list Ww2 Euro pistols.Seems i remember 9mm clocking a bit higher then your #s.

Only a Shield gives me problems; it won't cycle.
