I have a 4013 tsw, with a hogue grip. I ordered a factory grip from midway, but the spring on my 4013 does not fit the lower part of the grip that was sent me. The spring on my pistol is square, and sets at the but of the grip frame, while the grip sent me has some fitting there that would be round and must be cut away from the grip to fit my gun. The part is marked 4013 TSW, 4053 TSW 4056 TSW. Is it made for a later model gun, or are they made to be cut to fit?

If you had a Hogue grip on it, be sure to remove the black plastic spacer from the bottom of your frame, exposing the silver spring cap. The spring cap fits directly into the factory grip.

I didnt realize that was a spacer . I have been carrying it with that fat hogue grip in a shoulder rig.
