DeepFried Posted September 3, 2023 Share Posted September 3, 2023 11 hours ago, hlsccsfa said: All of my 3 S2s have CGW extended FP and reduced power FP spring and CGW reach reduction kit. #10 hammer spring would pop Federal and Genix SPP (provide that your press has adjustable primer seating depth to seat it deep enough) 100%. For any other primers, I would switch to 11.5# hammer spring. arent Ginex on the opposite end of the ‘hardness spectrum’ from Federal? I don’t have experience with them, thought they were really hard. Link to comment Share on other sites More sharing options...

I don’t have experience with them, thought they were really hard. Ginex primers are very hard to seat properly, especially on Dillon 650/750 (doesn’t have primer seating depth adjustment). Not a problem on a 1050/1100, Mark 7 or X-10. Once seat to 10/1000”, an S2 with 10lbs hammer spring or a Stock 2 with Extreme light weight hammer spring and Titan hammer would make it pop every time.

FALAR Posted September 7, 2023 Share Posted September 7, 2023 (edited) I settled on CZC 12lb. It brings the DA to 5.5-6.25lbs and with extended firing pin and reduced power firing pin spring I've tested it with the hardest primers I know of----IMI and M882 and have had 100% ignition.

PA_USPSA Posted September 11, 2023 Share Posted September 11, 2023 I have a CZC 13 lb. hammer spring with a stock firing pin and reduced power firing pin spring. The trigger pulls are 7.5 lbs. DA and 3.25 lbs. SA. I had 100% ignition with multiple makes of primer. All of the primers were domestic (CCI, Winchester, etc.) Link to comment Share on other sites More sharing options...
Runswithwood1 Posted September 20, 2023 Share Posted September 20, 2023 I've got a 13 pound in my s2o, along with reduced firing pin spring, so far it's working alright Link to comment Share on other sites More sharing options...
fireman1776 Posted November 10, 2023 Share Posted November 10, 2023 Using supervel ammo the 11lb had about 15-20% light strikes. 13lb saw improvement but still around 5% light strikes. Way too many for me. Link to comment Share on other sites More sharing options...
WxGuy Posted November 10, 2023 Share Posted November 10, 2023 11.5 hammer spring, ex firing pin, reduced firing pin spring. This combo has been in my 75s and Shadow 2s without any hiccups. Keep your firing pin channel clean and I use Wilson Combat Universal grease/oil on the rails. Link to comment Share on other sites More sharing options...

PA_USPSA Posted November 10, 2023 Share Posted November 10, 2023 I agree it's the ammo. I shot over 1000 rounds using CCI and Winchester primers with a CZC 13 pound hammer spring, 11 pound recoil spring, stock firing pin, and reduced (RAMI) firing pin spring. I haven't had any malfunctions whatsoever. Link to comment Share on other sites More sharing options...

ES13Raven Posted November 15, 2023 Share Posted November 15, 2023 (edited) My question is: Why would you NOT want to install the Extended Firing Pin & Spring? It's one of the least expensive things you can do to improve reliability. Edited November 15, 2023 by ES13Raven Link to comment Share on other sites More sharing options...

At least much less drop safe than factory Since this forum is based on competition shooting as opposed to CCW or home defense, that’s not much of a concern. If you are that worried about it, run it cocked & locked, or half cocked with the safety on. Or better yet, run a gun with a firing pin block like the SP-01.

PA_USPSA Posted November 17, 2023 Share Posted November 17, 2023 USPSA Production division requires the hammer to be down at the start of the stage. Cocked and locked or half cocked is not an option. I replaced my extended firing pin with a stock firing pin to make the gun drop safe. I've never had a malfunction using the stock firing pin, so there is no disadvantage to using it.

Many shooters have shot Production with a Shadow, including myself and have never been worried about dropping it from the time it takes to manually lower the hammer to taking the first shot.

While thousands of shooters have used Shadows with extended firing pins without anything bad happening, I replaced my extended firing pin with the stock firing pin after the RO was killed when the Shadow 2 with extended firing pin was dropped, went off, and killed him. Even a 1 in a million chance is too high for me. YMMV. Link to comment Share on other sites More sharing options...
slavex Posted November 21, 2023 Share Posted November 21, 2023 (edited) I used an extended firing pin as a sponsor sent me one with a bunch of other parts, took it out after finding it didn't make any difference and at the time it not being legal to use in competition. Never bothered with one after that. I think they are a waste of money. Super light firing pin spring, yes. I just stay at 10lb for main spring and it lights off everything, Ginex, CCI, Federal, S&B, Fiocchi, Armscor, Remington, Winchester, I've never had an issue with a regular firing pin. I used to run an 8lb main and did suffer the odd light strike, same with 9lb with some of my practice ammo, so I just went with a 10lb and stayed there. The extended firing pin didn't help, only spring weight did. Edited November 21, 2023 by slavex Link to comment Share on other sites More sharing options...
Yoseppy Posted November 25, 2023 Share Posted November 25, 2023 I'm using a 12# czc hammer spring with the cajun extended firing pin and spring. Ive yet to have a light strike with this combo I'm getting about a 4.5# DA pull on my Lyman trigger gauge. Link to comment Share on other sites More sharing options...

Also, all other brand of primers run perfectly. P.S. I run single stage press. Link to comment Share on other sites More sharing options...
