I upgraded to a set of Hogue wrap around grips on my Sig P238 to improve the grip and the Hogue grips make a huge difference in the feel of the pistol. SIG Sauer P238 Rubber Grip with Finger Grooves  - $24.95 : Hogue Inc., The Best Value In Handgun Grips, Rifle Stocks and Accessories - Bar None! But the stock Sig grip screws while functional just didn't look right on my Duotone 238. So I ordered a set of 1911 Slim stainless steel grip screws to give them a try. They looked great but were still a bit too long for the 238. So rather than file or grind them down I just added a small O ring (1/8" hole, 1/4" dia) to each screw and that did the trick.
