If your barrel drops open easily and has any side to side movement when opened, that "play" at the hinge does not go away when the barrel is closed, and it permits the barrel to move in an inconsistent manner while the bullet is traveling through it. To reach a barrels accuracy potential, this play at the hinge area must be removed. Stop wasting ammo trying to get your barrel to shoot, just oversize the hinge pin.
The hinge pin holes in Encore barrels and frames vary much more than the holes in Contenders, so much so that in some instances the hinge pin must be at least .003" larger than "stock" in order to get the same degree of precision fit common to the Bellm Oversize Contender Hinge Pins. Stainless steel frames are prone to accept the 2x pin, a result of galling and/or lack of lubrication.
The hinge pin holes in Encore barrels and frames vary much more than the holes in Contenders, so much so that in some instances the hinge pin must be at least .003" larger than "stock" in order to get the same degree of precision fit common to the Bellm Oversize Contender Hinge Pins. Reaming for these 1x pins is virtually never necessary. At .4377" they fit most all factory and custom barrel hinge pin holes. Testing the fit of the 1x pin in each hole gives an indication as to whether the next larger pin is needed to get the optimum fit desired, that of a bank vault door opening and closing. I know, you never had the privilege, but you get the idea. It does not shake and rattle all over the place. Use the 1x pin as a gauge pin. If it is not tight enough, consider it as a gauging tool to determine if a larger pin is called for. Taking accurate measurements of pins and holes is common among machinists, but not in the realm most folks are familiar with. Thus, the best solution I have found to bridge this technology gap is to simply use a process of elimination by going from one size pin to the next. Anyone can tell if a pin is loose or tight, right? The Encore hinge pin system is a well proven system. "Trial and error" is working very well, and groups are tightening. That is what counts. So, start with the 1x pin unless you have a means of accurately measuring your hinge pin holes in your barrels and frames. By the way, calipers are not accurate enough to give more than a rough idea. Trying a pin is still the best method available to most shooters. Add a 1x pin to your cart and get started toward better shooting Encore barrels.
Test fitting the hinge pin fit is as Simple as lubricate the hinge pin, frame and barrel hole with a common cutting/tapping or heavy viscosity oil, the key is ANTI binding/bearing lube. Center the hinge pin on a given hole checking for axial play and resistance. If it is not tight enough, consider it as a gauging tool to determine if a larger pin is called for. When installing the oversized hinge pin, always install the stock hinge pin first, then tap out of the way with the oversized pin. Always remember the lube.

Authorized T/C Dealer/Retailer
Why buy from us?
Our T/C parts business was founded by my father in 1979 after an apprentice under P.O Ackley, creator of the Ackley Improved rounds. A customer shooting matches in SLC Utah stopped by my fathers shop shortly after opening his doors with a Contender that had a number of issues affecting it’s accuracy. We simply fell in love with the veratility of the weapon but after multiple attempts of obtaining custom made parts from the factory to correct the issues he started making his own. We design and produce hundreds of custom made products for the T/C single shots with an emphasis on improving function and accuracy. We are a FFL dealer and full time custom shop business open for orders and technical support 5 days a week and currently shipping 6 days a week.
