I recently bought a used CZ SP-01 Tactical 9mm on-line (Internet sale). When I picked up the gun at my local pawn shop (use them for FFL transfers), first thing I did was try to drop the mag and that's when I noticed that the mag catch was reversed for a left handed person (I'm right handed). I haven't gotten a chance to remove the grip panels yet to see what's involved in trying to reverse the mag catch back to right hand mode. Is this something fairly easy to perform without too much trouble, or is this something I should have a competent gunsmith perform. Thanks.
