Tm 5.1 Hi Capa Hammer Spring

[Nicayu]

Hi All

 

I'm upgrading my recoil spring to 140%, should I change my hammer spring at the same time or is it ok to continue with the stock?

 

Many thanks in advance.

Only reason to replace the hammer spring is if its light striking. Will only decrease efficiency. Also placing a bb under the stock spring can help if it is rather than buying a new spring.  Personally I wouldn't replace any of the stock springs unless essential but that.s just me.

Hi

I asked because the recoil spring comes with a hammer spring.

I am changing the recoil spring due to a new metal slide.

Thanks for your help.

NP. Not even essential with a metal slide tbh, especially a good aluminium one .I'd see how it runs on both.

I've been doing some testing.

I've had all sorts of problems since fitting both springs.

1st I noticed the pistol didnt shoot a BB every time.

2nd The slide stopped just short of fully forward, this is due to the BBU seal/O ring becoming faulty somehow.

3rd The slide won't lock open when the mag is empty.

 

So, I have a new CCT seal on the way and have removed all of the new springs replacing them with the stock.

 

Heroshark, you were right.
