With the same spring setup: 14lb recoil,29N striker, I have had a good number of failure to chamber situations on unloaded starts. Manually racking the slide, it sometimes doesn't have the oomph to close all the way or sometimes even fully strip the round off the mag. Never had this problem with the polymer. I talked to another guy running the same setup with the Rival-S and he reported similar things happening. Haven't any problem when the gun is cycling itself, but when I need to, it's happened a few times. Not exactly sure what would cause this, but worth monitoring.

So far the only thing on the slide I have noticed being different is the extractor spring seems like it is at least double the strength of the polymer Rival and SFX. Not sure why that change was made.

One other thing: you know when reassembling after a field strip, you place the slide on the frame and essentially rack it and it goes into position. My S has a resistance to that rack that my polymer doesn’t. Requires a good bit of force to get it to move from that initial alignment position. Not sure what is causing that either.

When pointing the Steel gun barrel vertically into the air, I could pull the slide back to unlock the barrel and watch if the slide went back into battery. 14 and under did not go into battery. I put in a 15lbs spring and it goes into battery. Maybe the new S slide has a tighter tolerance on the rails than the ploy frame allows. My FP spring is stock. I'm going to order 16-17 and 18lbs springs. A mounted optic may need a higher spring weight.

My SFX has the FS Zombie Pro shoe too. Both guns are shooting the same ammo which is Freedom 147g HP and NC Shooters 125g RN Blue. PF is 128 and 133. Next will be a benchrest test to determine which is primary ammo for matches.
The original 10 pull average on the stock Rival S trigger was 3.2 and it's good for me. The 125g Blue had the best grouping freestyle at 30' with .75-1 second splits to feel the gun and monitor the muzzle dip. I think this is where I'm going to shoot the gun for a while before thinking about other spring changes.

Is your Rival holster a poly Rival RHT or something else? I got around to putting my Rival S factory holster on a Boss hanger today. Had to get the rubber shims just right to pull straight out of the holster. My modified SMC poly Rival holster (thanks again Chef1 from Enos) works great. The steel Rival is 1.1mm taller and it's all in the picatinny rail. A little wood file does quick work on Kydex.
