Yes you can, there are two different models available ,one is a powerful vintage collectors item that shoots .22 lead pellets called the Schimel, here.. http://www.gunstar.co.uk/Air-Pistols...-gs155734.aspx and the other is a currently available new replica that fires steel .177 BB's by Umarex.A review of it here.. http://www.youtube.com/watch?v=6XkqURQ8Oh4
As an alternative and inspired by the Luger, though a Co2 rendition of a Ruger pistol is the Crosman MK1 in .22 and MK2 in .177 these are vintage pistols and like the Schimel command a higher price. Link here, http://my.tbaytel.net/coopers/CrosMkI/review.html
