Signal7 Posted November 18, 2023 Share Posted November 18, 2023 @WxGuy Thank you for that, definitely a difference here and doing it side by side really shows the difference. Any idea of those plunger parts are interchangeable? Link to comment Share on other sites More sharing options...
WxGuy Posted November 19, 2023 Share Posted November 19, 2023 They look like they could be swapped out. Link to comment Share on other sites More sharing options...
Signal7 Posted November 25, 2023 Share Posted November 25, 2023 (edited) I sent both barrels (Rival and Rival-S) out to PD to have them reamed, so we'll see how it goes once they return and I get back to testing. As an FYI, patriotdefense.com is having a sale right now (Black Friday) for 30% off their reaming service using code: PD30 ($17.99 savings, so definitely worth it) https://patriotdefense.com/patriot-defense-9mm-barrel-reaming-hard-coating-melonite-dlc/ Edited November 26, 2023 by Signal7 Spelling and grammar.

Signal7 Posted December 21, 2023 Share Posted December 21, 2023 (edited) So both barrels have been back for a while now and I've shot the Rival a little and Rival-S quite a bit. The Rival-S needed a new extractor spring (CZ spring with one coil but down) to eject reliably and it's still hit or miss on syntech ammo. Mostly runs the syntech 150 ammo, but will occasionally jam up and fail to go in to battery. All 147 copper jacketed round nose run fine, rarely does it choke on anything now. The Rival is good to go now, I did add a tungsten guide rod and glock return spring, it's not quite as picky on ammo, but I've only shot it a few times. Has anyone polish their feed ramps and/or had the barrel mouth "customized" to allow truncated cone / flat point ammo? (My apologies in advance if some of my nomenclature is incorrect).

Signal7 Posted July 29 Share Posted July 29 (edited) As a follow up to this and the Rival-S, I did away with the tungsten guide rod, and found that it'll cycle and shoot any round nose bullet just fine. It will get a bit picky on truncated cone rounds, so I just stick to 147 RN (copper AND coated run fine) and it's good to go.
