Ill second Marc's comments. I own three. TAN Witness and Swiss Arms versions. I do use them for "target" shooting into Plumbers mate putty at up to 6yds and challenge myself to stay in 1inch groups (or smaller on a good day). Some inner or outer barrels need some slop removing and others are fine out the box. Have a look at Marc's site for fixes & maintenance. I'm still running my T/W after 5yrs so they can last too. ATB.
