[FARRIER]

  not even one person have any advice! pinning 19 round spo1 mags to 10 rounds, do's anybody have any advice so I could do it my self.
thanks in advance.

I have seen an acrylic block shaped & placed into the mag & trimmed to allow 10 rounds only to fit. Grub screw to fix.
STI/SVI mags have an aftermarket follower available with a plastic pyramid that comes up through the mag spring & is trimmed to suit.

Cheers, Ando.

I think it would be easier to try and trade your 19 round mags with someone who has the 10 round mags or just buy the 10 round mags instead.

The reason for the spo1 mags, is that I want the mag bases,the 10 rounders have a plastic base that breaks when it hits concrete floor.
I heard from Angus that CZ UB has come out with some alum mag base for the 10 rounders but when will they be available

[Walt Sherrill]

In IDPA you're limited to 10-round mags, and I've shot thousands of rounds indoors in matches, with empty mag drops,  where the mags hit concrete or tiled floors -- and have never seen a plastic base on a CZ mag break.  (Not that they won't, but my experience says its not likely to be a big problem.) 

Have you seen this a lot, or is this just something you're concerned about?

[FARRIER]

I was just a little concerned, and you know I heard from a guy that heard from a guy!about mags breaking?

Here are the aluminum bases that you were talking about on the CZ-USA online store:

I have two of the 10 rounders. If you want to trade or work out a deal let me know. John

I havn't got any of the 19 rounders just the 10 rounders but I was thinking about getting some because I like the mag bases.
But thanks for your offer!
