You guys have given me some great ideas for the upgrades. Right now I'm thinking:

1. HBI - trigger spring kit and safety delete

2. HK parts - tri lug for my suppressor - look like this one is a better fit and goes well with the spring retainer clip

3. Burris Fastfire and American Defense mount - I have a springfield XDM 5.25 with mount so can use the same optics and save some $$$.

4. Only thing pending is figuring out which suppressor - likely will just get a dedicated 9 mm rather than hybrid - so confusing looking around for reviews, etc....

Currently there are only triggers that only change how it looks and feels, they don't do anything for the pull? It's just the spring kit? Is anyone polishing the triggers and getting good good results?

you have to replace the springs or you'll be stuck with a 12+lb pull.
When I had my Scorpion I asked and found out that Bill Springfield was willing to do his polishing work on these parts.

I did a simple polishing job on the contact points along with trigger spring kit.

The spring kit drops my trigger weight to about 5lbs.

Polishing made it smoother but still a bit creepy (nothing like a crsip AR15 glass rod break). I'd say closer to a smooth AK trigger.

Hope that makes sense.

Given the popularity of the scorpion, I'm sure we will see aftermarket products soon.

The spring kit worked wonders for me. Currently I am just running a Magpul vertical grip and Aimpoint Pro on my approved Form 1 :) If any of you are on the Eastern side of the state, you are welcome to try out the scorpion in it's true form!

The spring kit gives it a decent trigger pull, but for me it's also really slowing down the trigger reset.

I'm going to do some polishing and see if that helps.
