Stribog SP9A3G
I live in California, reason for that specific model.

Looking for opinions on the Stribog. I've watched a ton of vids on Utube about this PCC.Does it NEED any parts changed or is it good out of the box? Obviously I will add a dot and light, but besides that, does anything else need to be upgraded?

I already have a Magpul edition CZ Scorpion 3+ that I love. I just love the PCC platform and want another. I really want to compare the roller delayed system to the blowback and apparently the Stribog is lighter which is a plus.

You don't need much depending on what you intend to do with it. Suppressed you probably want some specific changes.
But head over to the suppressed weapons section of SIGforum and look under a post called Home defense suppressed-9mm and see the changes that 1lowlife documented in that thread as a start of the kinds of things that are available.

I have the factory mag SP9A3, and don’t know if there are any other differences beside the lower for Glock mags, but I’d say the minimum upgrades are the HBI short stroke buffer, extended bolt release, and reduced weight trigger springs. Also, different locking blocks can give softer recoil, especially if running suppressed.

Stribogs are great!

I have an SP9A3s(5" barrel, stribog mags) and it scratches my MP5K itch nicely.

I ended up ordering it today. Got the one that uses Glock mags. Also purchased a couple parts from HB for it.

Going to wait to see what the trigger is like, but I have a Timney waiting. Also in the works is a Holosun with a riser just like my Scorpion.

Congrats! Post a pic when you bring her home!
These things are like the old DSM cars from the 90s, so many mods.

You can buy a lower that lets it use your scorpion mags too.

Have you done anything with the factory trigger?

I posted about the Timney, but upon further research, I'm not so sure it will fit without replacing the lower to accommodate an AR15 trigger. It does say it fits Stribog, but I've also read that the trigger is a bit too narrow to fit and needs shims to fit correctly.

I should have ordered the spring kit from HB when I placed my order the other day. Now sadly, I'll probably pay more for shipping than the actual kit for $9.00. Roll Eyes

For me, the stock trigger with the HBI spring kit is fine. The flat faced skeleton trigger in the newer Stribogs seems to be improved from earlier ones. Aside from finding a trigger that fits, you have to worry about the trigger working with the safety. The Lingle lower that takes an AR trigger and uses Scorpion mags is over $300.

I like my Stribog enough that I invested heavily in mods as soon as I shot it. Mine has a pretty decent factory trigger but I now have a binary trigger(installed before SB-003 took effect) in the stock lower and I bit the bullet for a lingle lower so I could put a geiselle in it.

This was all a knee-jerk response over the summer, to legislation that I took offense to, so I emptied my wallet. You can probably mod your gun more deliberately.

Get one of those fancy H&K braces from HBI when you order the trigger spring :-P
