Just got back from the Houston Gun Show. I picked up 2ea 20rd PMI mags, I noticed at the show they looked short like 15 rd mags, but 3 different venders, all had the same factory sealed 20 rd mags that looked short. 2 of th venders wanted $49.95 ea.

I just got out my PMI 30 rd, and my 20 & 30 rd Western mags to compare lengths. The PMI 30 rd is 3/8" longer than the 30 rd Western, But the PMI 20 rd is 7/8" shorter than the Western 20 rd mag!:confused:

They load up ok, and latch in the mini fine with the bolt closed, but since I paid $42.95 each, and drove for 2 1/2 hrs each way, paid $7 parking, and $6 for a ticket, you think they work? Of course not! You think I'm :mad: ? No I'm :cool: .

I will TWEEK em, till they work!

I believe it to be the old Mag latch length problem. Ref: http://www.perfectunion.com/forums/showthr...=&threadid=1540

Fixed already! It wasn't the mags, it was a mod I had done to the forestock liner. Ref: http://www.perfectunion.com/forums/showthr...27475#post27475

My 5 rd Ruger mags, measure exactly the same as the PMI's. Both of my new PMI 20 rd mags passed the manual feed/ejection test after I removed the screw. Will replace the button head screw with a flush head screw.

So far the 20 rd PMI's have passed all tests. I will report on the range test upcomming.

Would you please explain the "manual feed/ejection test"?:

("Both of my new PMI 20 rd mags passed the manual feed/ejection test after I removed the screw.")

I have 4 I would like to "test" without jamming the rifle by testing with live fire.

Thanks!

Hey azroaddust. When I get a new mag, I first load it up, then see if it locks up with all the rounds, and bolt closed, or if not then with bolt open. I next manually cycle the slide rod manually with safety on, to see if the mag has any problem feeding, or ejecting, as I empty it at least 2 mag's full. IF it hangs up manually it will shurly jam when firing. If it dosen't pass these tests, tweeking is in order, before I go the the range, for live fire testing.

By doing it in this order it cuts down on frustration, embarrasement, and ridicule of other thoughtless shooters.

Thanks cajungeo. Makes sense.

By "tweaking" I assume some gentle bending or grinding on the mag will be required and it may be obvious where the rounds are hanging up, huh?

Geez, wish I had you for a neighbor or at least within driving distance. It would be nice to have someone show me some tricks of the trade so to speak!

Once again, thanks for your input.

Being in aircraft, we don't bend parts, only reform them. The tweaking areas include the feed lips, and either trimming or adding material to the mags latch pad.

Just about everything I know about the mini, is contained in the collective wisdom of this forum. I have read every post, and have learned a bunch.
