Hi all. Just got a brand new gen 2 sub2k. I got the S & W 9mm model that has the multi-mag capability. I tried to convert the mag catch to the P320, but it doesn't seem to be working. After putting on the P320 catch, my standard size P320 mags are not catching. And ironically, the S&W mag still catches with the P320 converter. Anybody face this issue? Any advice? Thanks.
