I have been wanting a Ruger SP101 with a 3 1/16 barrell for quite sometime. Well I have finally gotten one. It is used but the lock up is tight as a bank vault and the cylinder gap is impressive. I wont be able to try it out untill this weekend. I am just wondering if there is anything I should do? I would like to smooth it out the trigger is a little sharp on the edges so I would like to round all the sharp edges the entire gun. What is the best way to smooth the edges?I know there are places and points that can be smoothed out to improve things. I know there is "IBOK" treatment but I dont remember where I have heard of that. I am open to suggestions. Thanks guys
