I recently purchased a used model 38-1, I think a late 80's or early 90's vintage. I did a brief inspection at the time of purchase and besides some minor wear on the frame it looked alright to me. Once I got it home I looked closer and noticed that there is a gap between the frame and yoke when pressure is applied to the right side of the cylinder when it is closed. When the trigger is pulled and held to the rear the cylinder seems to lock up pretty tightly. How bad off am I?
