My Zenith Z5P is a great gun, but it is picky about magazines that fit easily in the magwell. Once they seat, all my mags function perfectly in the gun.
HK (German) magazines don't insert easily, and the US made 15rd mag I bought off HKParts is REALLY difficult to insert.
However, the MKE 30rd mags fit perfectly and easily insert into the magwell.
So, I'm looking to stock up on a few mags but I want to find MKE mags to make sure they fit well. Problem is, MKE mags are about as hard to find as Zenith guns right now! (HKParts has them for $65, but I've seen them for a lot less and was looking for a better price).
I'm thinking about trying out a KCI mag. Does anyone know if KCI mags will fit in a tight magwell?
I might recommend that you send it back to Zenith under warranty so you can properly use real HK magazines, because other companies' magazines are similar specs.
I already sent it back to Zenith for warranty work once (extraction/ejection issues as well as the magazine well). They performed the following work:
Polished bolt face
Tuned and polished extractor
Extractor spring replaced
Magazine well adjusted
However, the magazine well still won't easily accept the HK mags I have or the USA magazine. They asked me to send in the HK mags for them to inspect, etc., but I passed up on this as they stated they had already "adjusted" the magwell. I expected this to fix any issues I had.
As the HK mags work (just a bit stiff getting in), I will just buy MKE mags as they are very high quality in my opinion.
