Hey everyone! I am looking into getting the AEK Trigger from Apex. (https://apextactical.com/store/product-info.php?pid60.html) I know a lot of you recommend Apex kits. Is there any other part/mod needed besides the AEK Kit to replace the stock trigger. I have seen their competition kits, but they do not recommend them for carry or self-defense use, which is what this pistol is for. I'd love to know if any of you bought the AEK kit, then found yourself needing to buy other parts as well?
