Will2K Posted March 22, 2017 Share Posted March 22, 2017 I'm hoping to lighten some springs on a stock shadow. Thinking about going with 15 or 13 lb main spring and same for the recoil spring. Do I also need a lighter firing pin spring or an extended firing pin or will the stock ones work? I just started reloading for 9mm as well and have 2000 federal blue box primers on hand. Would also still like to retain possibility to reliably shoot factory... what do do you all think? Link to comment Share on other sites More sharing options...
bsand Posted March 22, 2017 Share Posted March 22, 2017 I have a shadow custom from Czc. It came with 11lb recoil and 13lb mainspring along with a reduced power firing pin spring and extended firing pin. It was flawless with factory ammo (Speer lawman was flawless, uses CCI primers I think). But was having issues with other reloads mostly CCI and Winchester. I've recently switched to federal primers only and even small rifle ones go bang all the time. Not a single malfunction in 1000 primers.

Will2K Posted March 22, 2017 Author Share Posted March 22, 2017 Cool thanks very much! I'll try something similar. Link to comment Share on other sites More sharing options...
gixxerjunky Posted March 22, 2017 Share Posted March 22, 2017 All I load is WSP and my CZ shadow from CZ Custom lights them all off. I also have about 20k through it and have never changed any of the springs. I really need to go in and replace them all just haven't been paying attention.

BeerBaron Posted March 24, 2017 Share Posted March 24, 2017 I would go to Cajun gun works and buy their recoil spring pack. From memory 10 or 11lb was what I settled on. For the main spring their 8.5lb combined with their extended firing pin and light firing pin spring will light off federal. The 11lb main spring with the same extended fp and light fp spring will light off factory too. Link to comment Share on other sites More sharing options...
bsand Posted March 24, 2017 Share Posted March 24, 2017 Oh if your changing springs get the floating trigger pin and reduced power trigger return spring from cgw. Sent from my Pixel using Tapatalk Link to comment Share on other sites More sharing options...

Prerunnertrd Posted April 4, 2017 Share Posted April 4, 2017 I'm running 8.5# mainspring and federals light them off. Occasionally I do get light strikes but that's operator error on not seating the primer deap enough Link to comment Share on other sites More sharing options...
CTD_P2A Posted June 24, 2017 Share Posted June 24, 2017 What is the benefit to switching to the floating trigger pin? I'm planning on buying the tuner's pack from CGW along with the extended firing pin/spring and just wondering if I should consider adding this to my cart.

Focker Posted June 24, 2017 Share Posted June 24, 2017 The floating trigger pin makes it a lot easier to change out the trs when it breaks. Or if your smart it makes it easier to change it out before it breaks. I'm not smart. Link to comment Share on other sites More sharing options...
CTD_P2A Posted June 24, 2017 Share Posted June 24, 2017 Copy, thanks Focker! I'll try and get my smarts up. Link to comment Share on other sites More sharing options...
gtaylor07 Posted July 15, 2017 Share Posted July 15, 2017 Went with the 13lb in my SP01 before, but just recently changed to 11lb and really enjoy how it shoots. Brass definitely elects further, but seems to be within 10ft.Sent from my Moto G (4) using Tapatalk Link to comment Share on other sites More sharing options...
jripper Posted October 15, 2018 Share Posted October 15, 2018 I run 8.5 Cajun hammer with extended firing pin/reduced spring for federal only. 11lb hammer will set off everything else I"ve tried in it. Link to comment Share on other sites More sharing options...
