These three frames are different as night and day in some respects and identical in others. So how do you know which is which?
Hang on tight.....Here we go......
Basic Differences
Frame Sizes: Encore is bigger than G2 or Contender,
Barrel diameters where they seat in the frame: Contender/G2 13/16," Encore 1" so they do not interchange, thus,
Scope Bases: Encores have the larger radius on the bottom,
Internal mechanism: Contender has a hammer block, Encore and G2 sears lock the hammer at half cock,
Trigger Mechanisms: Two different types of Contender trigger groups both of which are removeable while Encore and G2 trigger mechanisms are not removeable,
Firing Pins: Encore is center fire only, Contender and G2 have a selector on the hammer to fire either centerfire or rimfire,
Hinge Pin Hole Diameters: Encore is 7/16" (.4375"), and Contender and G2 are 3/8" (.375"),
Internal Frame Mechanism Springs: No Springs in the Contender frame interchange with Encores & G2s,
Forend Screws: Contenders & G2s use No. 10x32, and Encores use No. 8x40 screws,
Hammer Extensions: Two different sizes for Contenders--vintage with the selector lever on top of the hammer is the same size as on Encore and G2,
Dry Firing: Encores and G2s should not be dry fired unless the firing pin bushing is removed and the fall of the hammer cushioned while Contenders can be dry fired continuously with no harm at all to the frame SO LONG AS THE HAMMER IS NOT COCKED (Dry firing simply releases the striker in the trigger group and gives the full effect of the trigger pull, independent of the hammer being cocked. Opening and closing the barrel resets the striker),
Forend Screw Hole Spacing: Hole spacings for handgun barrels is different carbine hole spacings in both Contender/G2 barrels and Encore barrels.
Grips/Buttstocks: Contenders, G2s, and Encores all take different grips, buttstocks, and forends.
Basic Things in Common
Hammer Springs: Encore and G2 use the same spring,
Trigger/Sear Springs: Encores and G2s use the same springs, none of which work in Contenders,
Locking Bolt Springs in the Barrel Lug: ALL barrels for all three frames use the same Locking Bolt Spring,
Hammer Extensions: Encores and G2s use the same hammer extension,
Scope Base Mounting: Barrels for all three have the same hole spacing and use No. 6x48 screws, but the holes in Encore barrels are about .050" deeper,
Retaining pins in the barrel lug: All use 1/16" diameter roll pins for the extractor and 3/32" diameter for the locking bolts, but retaining pins for the Encore are longer for the wider lug it uses,
Trigger Overtravel Screw: Same No. 4x40 screw size for all three, but length actually required for any given frame varies from 3/16" more common to Contenders to 1/4" which is more common to Encores and G2s,
Interlock Mechanism: All three frames have an interlock to prevent the frame from firing a round unless the barrel's locking bolts safely engage the frame far enough and thus push the interlock back far enough to permit the frame to fire a round,
Grips/Buttstocks/Forends: All vintages of Contenders are the same,
Trigger/Sear Spring Pliers: Use for both G2 and Encore,

Good luck and good shooting...

Here is what I found. The barrels are the same. The difference is the locking lugs or bolts as TC calls them. I have a pre 150,000 serial frame in 35 rem and a G2 with a new 7-30 bbl. The 7-30 bbl will work on the old frame, but it is hard to open sometimes. I took the bolts off of the 35 rem and put on the 7-30, voila, worked perfectly on the old frame. Got the new G2 frame, tried the 35 rem with then new bolts, worked perfectly. Tried the new 7-30 bbl with the old bolts, wouldn't even lock up. Summing up, what I have found on my 2 frames and barrels, if you can get some frame correct bolts and install on you bbl that you plan on using on that frame, modification by you or TC isn't required.
