Well its not hard to do the math here on this survey. its 25% here on this survey with problems and 75% without. That seems like to much for me. Im kind of wishing I went with the sig 522 instead. That thing shoots anything 22lr. And about the same price as the 1522. Watch nutnfancys review. This is how the 1522 should be for the money...

if somebody has a 1522 that shoots this reliably please post a movie proving it.
