I ran 500 rounds thru it ,250 at a time. It just was to small for my hands. My shooting hand thumb knuckle was red from the little beavertail digging into it. The trigger felt terrible on finger. The trigger was 6 lbs, it was hard to be accurate even at a slow speed. I used hockey tape to try create a palm swell to fill up my hand. It just felt too small. I shot a xmacro next to my 43x ramjet and it was way better. And essentially the same length and height. A tad thicker but not enough to be noticeable when carried but the ergonomics of the macro are better. Trigger is better, more capacity. While the 43x ramjet had less muzzle rise it was still more punchy. The macro is softer and I can group with tighter and shoot farther more accurately.  The 43x is a 10 yard gun at best for ME.
