Does the spring kit improve both DA and SA trigger pull, or just the DA?

Many thanks.


As others have stated above, the spring kit improved the DA pull considerably (it is at least 40-50% lighter as CGW states on their website) and there was a noticeable improvement in the SA pull. With just the spring swap, the SA pull on the Shark-C I was working on dropped to just a hair below 5 pounds. I have not polished up any of the internal parts so it will be a bit better after that. The CGW spring kit is definitely worth the $17 they charge for it. I would expect about the same results in a C100 -- I may have to pick one of those up next week and find out. :)

Does anyone know if an SRS-1 kit will work in a Jericho 941 frame safety pistol?

well I broke it! I was installing the kit but the Mag leaf spring just wouldn't go back to its ordinal position and with very little encouragement it snapped at the bend on the bottom nearest the slide. Now the gun still works properly and I cant see what the leaf spring was supposed to have done. I have a whole bunch of similar thickness spring steel so I can fabricate a new one but ... what is it for and yes I know they put it in for a reason but do I need it? Any advice would be greatly appreciated. I am hoping to take this out to the range on friday.

The Magazine Retention Spring, which is what I believe you are talking about, can be removed to allow Magazines to drop more freely during a Reload.  I removed them from my old late pre-B Cz75 and pre-Series 88 Tz75's and ran them without issue.  Never put them back in, even prior to sale.

For some Pistols it's just a mechanism cover plate.  It would be helpful to know just what handgun you are working on.

Alright I fixed it!!
So I bought this kit
https://cajungunworks.com/product/39250/

For my nifty new T 100

It is not a very complicated install right up until I had to reinstall the mag brake. It is seemingly fabricated of pringles potato chips except it might be a bit more brittle. I DID NOT apply a lot of force and the hook where it goes around the upper pin just broke off. It was way long so I thought I could bend another hook into it but ... it snapped. I found a wonderful video online of a drop free mod for anyone that wants to see it is here



From what I could gather it is designed in such a way so that the mag does NOT drop free. It puts tension in the form of a leaf spring on the back of the mag. You can certainly run the gun without it but then there is a danger I guess of damaging the hammer spring if you are speed loading mags since there is nothing between the mag and the hammer strut. In my other guns including my P 07 the hammer spring and strut are at least somewhat protected. I kind of like that little bit of tension so I designed my brake with just a bit of flex instead of going completely flat but you can certainly pull that crappy mag brake out and use flat steel of the proper thickness.

Years ago a friend gave me a giant spool of thin spring steel that he uses in his industry and I have been happily cutting out my thumb breaks from it for the few holsters with thumb breaks I get asked to do. It is 3 inches wide and the spool will get passed down to grandkids and was used in industrial garage doors. It is very tough, very springy, easy to grind on with a dremel wheel but not easily bent into tight radius's. Its really nice steel and kills anything I can buy as ready made thumb breaks.

I managed with some real effort to get a nice tight bend for the pin at the bottom and I am calling this an upgrade ... especially since its gold!  :)





Other than that  .. double action is AWESOME and trigger pull from half cock is just amazing now compared to what it was. Without overselling it ... from the half cock feels as good as MANY guns I have had shooting in single action. I dont have a scale but it really does almost feel single action from the half cock. $24 shipped priority and some fumbling around in the gun was well worth it.

You need a 1/8 punch for the slide to get the firing pin out and the 3/32 for the pin that holds the break. The pin that holds the hammer spring is near irrelevant since once you unweighted it the pin pushes out readily. The only other thing I would add if you can is a 3/16 in wood dowel to depress the Hammer spring.

Now here is to fingers crossed for no light primer strikes when I go out friday !!!
