Here my thought process regarding PCC’s.
1: EXTAR, AZ company out of Lake Havasu.

EP9, $420-ish, polymer AR pattern(4lbs), Glock mag with LRBHO. Comes with pistol brace.
EP10 and EP45 models due out later this year, slightly heavier(.50-1.0lb) and more expensive($50-100 more). Both have NP3 plated bolt and chamber, otherwise identical to EP9.
2: STRIBOG, Slovak company(same as Grand Power pistols)

SP9-A1, looks similar to B&T APC9. Key-mod or M-LOK, full Ambi controls with ability to swap charging handle side to side. Metal BUIS integrated into top rail. Cheap $20 mags/retrofit UZI mags possible. MSRP of $800, street price being around $700. AR pattern trigger, unsure which triggers will work though.
The SP9-A3 version is a delayed roller blowback, non-reciprocating charging handle, and if it comes in at the same price it’s a complete Scorpion EVO killer. All the features(and more) of a $1900 B&T APC9, for less than half the cost. It has yet to be imported though. Currently #1 on my buy list when it’s available.
Have also seen mention of a 9x21mm model, but unsure of any real details.
