Dumb 3 vs 3+ Question
« on: December 21, 2023, 02:01:13 PM »
I've been living under a rock (focusing on NV, bullpups and cans) for a few years and wasn't paying attention on the Scorpion line.  Now the PCC bug is back.

I have a 3 S1 and a bunch of mags for it.  I want to get a second and the 3+ isn't backwards compatible with the old mags, boo!  Am I too late to get a second standard 3?  Is there a magwell swap on the 3+ to get it to accept the old 3 style?

The 3+ is definitely a step up, ergonomically, from the 3 Evo. So I would be going the opposite direction and putting a 3+ lower on my old Evo 3. Problem is, no such 3+ parts seem to be available yet.

According to HBI, the 3+ lower is compatible with the EVO 3 Upper, so I would assume vice versa. The problem is finding the parts to make the change. Though the Evo 3 lower is listed on the CZ USA Webstore for $69 it is out of stock, as per usual.Also, a lot of the other internal parts are not listed or out of stock.They don’t seem to be available anywhere else. The EVO 3 is no longer listed on the CZ USA website, but I’m sure you can find them on gunwatcher.

An alternative would be to modify existing Evo 3 mags to work in the 3+. I believe Yeti Works has a free program to 3D print a jig to root out a divot on the Evo 3 mag so it will lock into the 3+ lower.

Good luck!

I don't think there is any viable way YET to convert the mags to 3 plus.  Even then - I have an old 20 rd Evo S1 that came with 20 rders that have the 3 plus cut, but they DON'T lock - figure that.

While the 3 plus is more "American" in its manual of arms, I like the paddle release.  Also, they went from a HUGE weirdly angled grip to a much better angled but tiny grip.  The one I just sent back to Cz as it has canted sights, it will not drop free with MP mags or ETS, so the easier mag button is pointless.
