I got the LCS SK 19 in .22 caliber and it can shoot slugs. Right now I'm running the Javelin 23 grain .218's at 950 fps and I have no problem with accuracy picking off starlings, pigeons and other pest birds at 100 yards plus. The trigger pull  long and rolling but it has never been a problem for me shooting. In fact for whatever reason is easier to stay on target during trigger up take. I rarely shoot the rifle in full auto but instead like the semi-auto feature for quick follow up shots at multiple pest birds. I always make it a habit when loading to countersink ammo, so rounds don't come loose during the magazine cycling.  will  be offering separate barrel kits for the LCS SK 19 . I bought an FX barrel kit so you can use the FX liners for Leshiy 2 it has more flexibility to shoot slugs and other pellets.
