I first took it out about a month ago and fired 197 rounds through it without one single hiccup. Last month I fired 17 Gold Dot 124 grain +P and 180 reloads using Berry's 124 Grain plated round nose. I am pretty sure last month it was a combo of W231 and due to the shortage...Unique.
Fast-forward to yesterday and all I had was reloads with 124 grain Berry's plated round nose over 4.7 grains of Unique and CCI SP primers. No crimps.
I was shooting from three 17 round magazines and a 10 round magazine.
I went through 350 rounds yesterday and had at least 10 malfunctions. It started out with 2 or 3 stovepipes, or spent rounds getting caught on those two ears on the barrel hood. It progressed to mostly double feeds....and to clear most of those double feeds I had to drop the magazine. On one instance the slide was in full battery with an empty in the chamber.
I didn't think to track magazines until I had already gone through 3 boxes of ammo. The last malfunction I had, I put that magazine(a 17 rounder) aside and didn't use it anymore. I then fired 2 entire boxes through the remaining two 17 rounder and the ten rounder and the only malfunction from those boxes was one time the slide did not lock back on an empty magazine.
I am almost sure I had malfunctions with more than that single magazine which I set aside, because I load them all at once and shoot them one by one, and I am sure I had malfunctions in every magazine for at least 2 boxes of ammo.
What is the most likely cause?
1) Bad Magazine? (springs are stiffer than any other auto mag I have dealt with, and the gun has only ~550 rounds through it spread across 4 magazines)
2)Under powered ammo...4.7 grains of Unique is actually below the starting load from Alliant's website and I have only fired this load through a Glock 19 (no malfunctions) and this SR9c
3) Need to crimp
4) Bad extractor, or not enough tension on extractor.
5)????
This gun is the most accurate, or at least the best autoloader I have shot other than a 1911. I'd like to have it as reliable as all the polymer wonders I have shot as well.
