nope not yet, i will be taking it off over the end of this month
let you know how it goes.
few people have told me to take it off now, and some of them are very well versed with the sw20
the reason im having issues is due to not runnign the adjustable toe arms as well, totenkoph has some adjustable arms for the front but now cbf with it and am just going to remove and see what happens.
