Improve Accuracy by tightening the barrel to frame fit at the hinge with Bellm Oversize Hinge Pins. Used by thousands of shooters with proven results for nearly 45 years.
Bellm Oversize Hinge Pins for Contenders, and now G2s, were first introduced in the mid-1980s when it became quite apparent that hinge pin hole tolerances in barrels and frames varied a lot, usually on the loose side of tolerances. These pins are meant to be an interference fit, meaning they are a force fit and must be tapped in with a hammer. The result is a barrel that opens and closes like a bank vault door instead of rattling around like a pea in a boxcar. With the barrel held securely and consistently from shot to shot, accuracy is improved, often VERY dramatically.Bellm Oversize Hinge Pins are not approved by Thompson/Center Arms or any other barrel maker. They are a custom application tailored to give you a precision fit and the best performance possible, which is something others do not address.Approved or not, I invite you to join the thousands of others who are enjoying the optimum accuracy a precision hinge pin fit provides. It is one of the best investments you can make in a Contender at any price and does absolutely no harm to either barrel or frame hinge pin holes if you follow the test for fit described on this site and in the instructions packed with the pins. At least 80% of factory barrels and frames accept the Bellm Oversize Hinge Pins, perhaps more. They also fit the majority of custom or "after market" barrels.They remove both the side to side and vertical play at the hinge and help equalize the side to side differences in frame hinge pin hole diameters.Do the simple wiggle test with the stock pin in each of the three holes, barrel lug and the two frame holes. If you can feel ANY movement at all on the pin when you try to wiggle it in each hole, it indicates you need a larger pin to take the play out of that hole.You will be able to feel any relative difference in fit from one hole to the next and will often find that one side of the frame hole is larger than the other. The oversize pin helps to equalize the fit side to side and eliminate side to side movement of the barrel.The oversize pin will also take out vertical movement at the hinge and tend to tighten lockup at the locking bolts.With the shake and rattle removed, as would be expected, any inaccuracy due to a loose fit is corrected.If you have opened and closed a high dollar break open trap or skeet gun, you know what a good fit feels like. Quite a bargain."Do I need an oversize hinge pin?" is a common question, to which I have to answer, "It's a no brainer."Tighten things up at the hinge like they should be with a Bellm Oversize Hinge Pin and watch groups tighten.
