Very nice upgrade. Have you tried the mags with the hollow floor plate for an extra round? Wilson Combat makes some good ones. But they may not work without modifying the magwell. I installed one on my Ruger. It worked fine with all my 7 round mags. But none of my 8 rounders would work. That was when I realized that a little gun smithing is needed. I used a dremel to blend it to the magwell on my gun. Here is a pic. Now all of my mags work.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
