Ever replace a trigger return spring?

[Cinny]

Bought a used MP9 Shield that I'm picking up today. I knew beforehand it had this bad spring so I ordered one from Brownell's. Per the schematic, it looks like you pop out the two pins and replace it. Anyone ever replace one? If so, easy...difficult?

Relatively easy. I think you need a hooked pick to make it easier, but I can't remember for sure.

I replaced one in my M&P 45 and my Glock.

If it is like other guns, be prepared for it to go flying away so wear glasses and maybe work on it in a bag

Watch a few videos. There is a specific way to hook the spring on the trigger bar.

What wrong with the spring?

HelPs if you get the little plastic slave pin from apex or make your own with the trigger return springs in m&p.

There is a spring under the sear that can help with trigger pull as well as with the striker block spring. Where are you located?

I made this tool from a small screw driver and Dremel. It helps to mount and un-mount the springs.

All, thanks for the suggestions.....much appreciated.

Picked up the gun (the lower actually) today from LC Action and when I got home, I put the slide on. Now, I can't get the slide to lock back nor can I remove it...arghhhh.

Checked out some YouTube vids and I guess this problem happens on occasion. Problem is there's a spring near the take down lever that gets out of place and prevents removal of the slide. As per the video (link below), I tried depressing that spring with a flathead screwdriver but to no avail. Looks like a trip to a gunsmith is in order. Check out at the 4:28 mark of this video. That is the issue I have now.

I bought a pair of HK trigger return spring pliers ($12 - $14) that make the job much easier to do. Others have just made their own pair by grinding a notch in the tip of an old pair of nn pliers with a dremel tool. I'm an electrician so $14 for a pair of pliers to do a specific job is more than reasonable, imo.
