Well I bought the 3.5 springs and some Flitz to help out with the trigger. I also added a match grade front sight blade with a drop of glow in the dark paint. I put the OEM next to it so you could see the difference. Money has been super tight, but these are very affordable.
First it the pic of the springs installed

Next is the Flitz

and last but not least are the front sights, what a major difference this has made.

Something to watch for, with the lighter Yellow spring you installed, watch for FTF (Failure To Fire), the lighter stricks on the 22LR primer on some ammo will not fire unless it is a solid hard strike. And the second item, painting the tip of the front sights is great, I also did that with white nail polish, really helps in fast aiming of the front.

Well I kept the blue springs if it doesn't work out. $9 isn't hitting the pocket too hard.

Nice ive actually been planning on painting the tip of my sight green

Was it easy to install the spring? I've been thinking of doing the same.

Very easy, just push out the two pins with a mallet and drift pin. and the hammer and trigger come right out. The instructions from JP tactical performance gear was pretty straight forward. I was new to this so I took pics as I went through it. Take your time if it is your first time. This was my first time and it was very easy. just make sure that when you put the pins back in for reassembly that everything is lined up straight before you start whacking things with a mallet. Here are the pins that you need to drift.
